Description
本発明は、洗濯後の衣類の肌触りを向上させることができる粉末洗剤組成物及びその製造方法に関する。 The present invention relates to a powder detergent composition capable of improving the touch of clothes after washing and a method for producing the same.
一般に、マグネシウムやカルシウムイオンを多量含む硬水より軟水での洗濯効果がさらに良く、このような理由から粉末洗剤はゼオライトなどの硬水軟化剤を通常含有している。従来、主に使われてきたゼオライトなどの硬水軟化剤は、水に不溶性であってすすぎの後にも衣類に残留する問題があるだけではなく、イオンの封入に比較的長時間がかかるため、硬水の軟化効果が比較的遅い。このため、洗濯時に残留するカルシウムイオンがアルカリビルダーなどからイオン化された炭酸イオンと結合して炭酸カルシウムを形成し、この炭酸カルシウムが衣類に残留する問題点がある。これを改善するために粒子の大きさを微細化させたゼオライトを使ってはいるものの、前述した問題点は解決されなかった。 Generally, the washing effect in soft water is better than hard water containing a large amount of magnesium and calcium ions. For this reason, powder detergents usually contain a hard water softener such as zeolite. Conventionally, hard water softeners such as zeolite, which have been mainly used, are not only water-insoluble and not only remain in clothing after rinsing but also take a relatively long time to enclose ions. The softening effect is relatively slow. For this reason, there is a problem that calcium ions remaining at the time of washing combine with carbonate ions ionized from an alkali builder to form calcium carbonate, and this calcium carbonate remains in clothing. In order to improve this, zeolite having a reduced particle size is used, but the above-mentioned problems have not been solved.
米国特許第６,７７０,６１１号明細書(特許文献１)においては、α−スルホ脂肪酸エステル界面活性剤とシリケートを使ってこのような問題点を減らそうとした。また、米国特許第５,９７７,０５３号明細書(特許文献２)においては、イミノジコハク酸塩を使って洗濯に悪影響を及ぼす重金属イオンを除去し、カルシウム塩の衣類付着を防止して洗濯後に衣類の色が薄くなる問題を減らそうとした。しかし、前述した問題点が完全に解決できてはいない。 In US Pat. No. 6,770,611 (Patent Document 1), an attempt was made to reduce such problems by using an α-sulfo fatty acid ester surfactant and a silicate. Further, in US Pat. No. 5,977,053 (Patent Document 2), iminodisuccinate is used to remove heavy metal ions that adversely affect washing, preventing the calcium salt from adhering to clothing and washing after washing Tried to reduce the problem of color fade. However, the above-mentioned problems are not completely solved.
一方、韓国特許第１９９３−０００３１５２号明細書(特許文献３)は、計量容易性を考慮して粉末洗剤ではなく錠剤型の洗剤を開示したが、アルカリビルダーと水溶性の多価カルボン酸を使って洗濯時に発泡させることで、錠剤型の洗剤が速く溶けるようにした。しかし、硬水軟化剤としてゼオライトなどを使って前述した問題点を解決することができなかっただけでなく、錠剤を製造するための打錠時にアルカリビルダーなどのアルカリ性物質とカルボン酸などの酸性物質とが接触する機会が多くなり、保管中に空気中の水気と反応し合って中和反応を起こすことでケーキングが形成されるなど、保管中の安定性が低下する恐れがある。 On the other hand, Korean Patent No. 1993-0003152 (Patent Document 3) has disclosed a tablet-type detergent instead of a powder detergent in consideration of ease of measurement, but it uses an alkali builder and a water-soluble polyvalent carboxylic acid. By making it foam during washing, the tablet-type detergent was dissolved quickly. However, not only the above-mentioned problems could not be solved by using zeolite as a water softener, but also alkaline substances such as alkali builder and acidic substances such as carboxylic acid during tableting to produce tablets. There is a risk that the stability during storage may be reduced, for example, caking is formed by reacting with moisture in the air and causing a neutralization reaction during storage.
前述した錠剤型の洗剤組成物だけではなくアルカリビルダーなど塩基性物質を多量含んだ粉末型の洗剤組成物においても、様々な理由で酸性物質を使う場合、中和反応によってケーキングが形成されるなど保管中の安定性が低下する恐れがあり、製造過程中においても酸性物質と塩基性物質とが接触して中和される可能性が非常に高い。 Not only in the tablet-type detergent composition described above, but also in a powder-type detergent composition containing a large amount of basic substances such as alkali builder, when acidic substances are used for various reasons, caking is formed by neutralization reaction, etc. There is a possibility that stability during storage may be lowered, and it is highly possible that an acidic substance and a basic substance are brought into contact and neutralized even during the production process.
一方、粉末洗剤は、一般的に酸性形態の高分子を用いてまずスラリーを製造し、これを乾燥して製造されるが、低密度粉末洗剤は高密度粉末洗剤に比べて冷水での溶解性に優れ、洗濯時に残留物が残らないという長所があって洗濯用として望ましい。特開昭６１−６９９００号公報(特許文献４)及び特開昭６１−６９８９８号公報(特許文献５)においては、密度が０．６ｇ／ｍｌ以下である低密度粉末洗剤を向流式噴霧乾燥装置を使って製造した。このような方法の場合、必ず乾燥過程を経なければならず、このため製品の溶解性が減少する恐れがあって、粉末洗剤製品の品質を維持し難い。また、複雑な過程を経なければならないため、製造工程コストが高く、向流式噴霧乾燥装置の使用による施設費及びメンテナンス費が高いという短所がある。このような短所を改善するためにヨーロッパ特許第３９０２５１号明細書(特許文献６)及び第５４４３６５号明細書(特許文献７)においては、ミキサー内でアルキルベンゼンスルホン酸を直接中和して低密度洗剤を作る方法が開示されている。これらの方法は、アルキルベンゼンスルホン酸塩を生成してから表面改質
剤を使う粒子化を行って粉末洗剤を製造するが、脂肪酸やアルキルベンゼンスルホン酸が完全に中和し難く、未反応物が残留して最終製品の品質が低下する恐れがあるだけではなく、しかも密度が高くて見掛け密度０．６ｇ／ｍｌ以下の低密度洗剤は製造し難いという問題点がある。
On the other hand, a powder detergent is generally produced by first producing a slurry using an acidic polymer and then drying the slurry. A low-density powder detergent is more soluble in cold water than a high-density powder detergent. It has a merit that it is excellent in that no residue remains during washing, which is desirable for washing. In JP-A-61-69900 (Patent Document 4) and JP-A-61-69898 (Patent Document 5), a low-density powder detergent having a density of 0.6 g / ml or less is countercurrent spray-dried. Manufactured using equipment. In such a method, a drying process must be performed, which may reduce the solubility of the product, and it is difficult to maintain the quality of the powder detergent product. In addition, since a complicated process has to be performed, the manufacturing process costs are high, and the facility costs and maintenance costs due to the use of the countercurrent spray dryer are high. In order to improve such disadvantages, in European Patent Nos. 390251 (Patent Document 6) and 544365 (Patent Document 7), a low density detergent is obtained by directly neutralizing alkylbenzene sulfonic acid in a mixer. A method of making is disclosed. These methods produce alkylbenzene sulfonate and then granulate with a surface modifier to produce a powder detergent. However, fatty acids and alkylbenzene sulfonic acids are difficult to neutralize completely, leaving unreacted substances remaining. In addition, there is a problem that not only the quality of the final product may be deteriorated, but also a low-density detergent having a high density and an apparent density of 0.6 g / ml or less is difficult to produce.
また、韓国公開特許第２０００−００４６６２９号明細書(特許文献８)においては、前述した問題点を解決するため、従来の向流式噴霧乾燥装置を用いた製造工程を使わずスチーム噴射ミキサー機を使った。すなわち、ミキサー内部にスチームと水を噴射してアルカリビルダー、アルキルベンゼンスルホン酸、及び脂肪酸を直接中和させ、粉末洗剤の粒子化、表面改質及び移送などの工程を連続的に短縮された工程時間内に行った。しかし、この方法はスチームと水を噴射する設備を必ず必要とするだけでなく、製造コストが高いという短所がある。
本発明は、硬水を軟水化する速度が速く、洗濯後の衣類への残存が少なくて衣類の肌触りを向上させることができると共に、保管時のケーキング現象がほとんどなくて安定的であり、かつ洗浄力に優れる粉末洗剤組成物及びその製造方法を提供する。 The present invention has a high rate of softening hard water, has little residue on clothes after washing, can improve the feel of clothes, is stable with almost no caking phenomenon during storage, and washing Provided are a powder detergent composition having excellent strength and a method for producing the same.
より具体的に、本発明は（ａ）酸性形態の水溶性高分子０．１ないし１５重量部、（ｂ）陰イオン性界面活性剤５ないし２０重量部、（ｃ）アルカリビルダー１０ないし７０重量部、及び（ｄ）アルカリ性物質との接触を防止するためにコーティングされた有機酸０．５ないし２０重量部を含むことを特徴とする粉末洗剤組成物を提供する。 More specifically, the present invention relates to (a) 0.1 to 15 parts by weight of a water-soluble polymer in an acidic form, (b) 5 to 20 parts by weight of an anionic surfactant, and (c) 10 to 70 parts by weight of an alkali builder. And (d) 0.5 to 20 parts by weight of an organic acid coated to prevent contact with an alkaline substance.
さらに、本発明は、酸成分と塩基成分との中和反応で発生する熱によって乾燥される粉末洗剤組成物の製造方法であって、別の乾燥工程がなく、（Ｓ１）前記酸成分として酸性形態の水溶性高分子及び陰イオン性界面活性剤を、塩基成分としてアルカリビルダーを調製する工程、（Ｓ２）前記酸性形態の水溶性高分子０．１ないし１５重量部及び陰イオン性界面活性剤５ないし２０重量部をアルカリビルダー１０ないし７０重量部と共に混合機に投入する工程、（Ｓ３）前記混合機に投入された（Ｓ２）工程の成分を均一に混合する工程、及び（Ｓ４）予め製造されたコーティングされた有機酸を混合する工程を含むことを特徴とする粉末洗剤組成物の製造方法を提供する。 Furthermore, the present invention is a method for producing a powder detergent composition that is dried by heat generated by a neutralization reaction between an acid component and a base component, and there is no separate drying step. (S1) Acid as the acid component A step of preparing an alkali builder with a water-soluble polymer and an anionic surfactant in the form of a base component, (S2) 0.1 to 15 parts by weight of the water-soluble polymer in the acidic form and an anionic surfactant 5 to 20 parts by weight are charged into the mixer together with 10 to 70 parts by weight of the alkali builder, (S3) the step of uniformly mixing the components of the step (S2) charged into the mixer, and (S4) pre-manufacturing A method for producing a powder detergent composition comprising the step of mixing the coated organic acid prepared.
本発明は、硬水軟化剤として通常使われてきたゼオライトなどの水不溶性物質の代りに硬水に存在するカルシウム及び／またはマグネシウムイオンを封入することができる水溶性の有機酸を使う場合に、硬水の軟水化速度が非常に速くて洗濯後の衣類に炭酸カルシウムなどが付着する可能性が非常に少ないだけでなく、硬水軟化剤そのものが洗濯後の衣類に残存する可能性が少なくて衣類の肌触りを非常に向上させることができるという驚くべき事実に基づく。また、本発明は、有機酸そのものの代りにコーティングされた有機酸を使うことで、洗剤組成物に通常含まれるアルカリビルダーなどのアルカリ性物質との接触を防止して中和反応の発生を遮断し、これによって洗剤組成物の安定性を改善することができると共に、有機酸の軟水化能力、すなわち、イオンを封入する能力を保管中にも維持して、洗濯後の衣類の肌触りを向上させるなどの洗濯効果を維持し続けることができると
いう驚くべき事実に基づく。
In the present invention, when a water-soluble organic acid capable of encapsulating calcium and / or magnesium ions present in hard water is used in place of a water-insoluble substance such as zeolite that has been usually used as a hard water softener, Not only is the water softening rate very fast and the possibility of calcium carbonate etc. adhering to the clothes after washing is very low, but the water softener itself is less likely to remain in the clothes after washing. Based on the surprising fact that it can be greatly improved. In addition, the present invention uses a coated organic acid instead of the organic acid itself, thereby preventing contact with an alkaline substance such as an alkali builder usually contained in the detergent composition, thereby blocking the occurrence of a neutralization reaction. Thus, the stability of the detergent composition can be improved, and the water softening ability of the organic acid, that is, the ability to encapsulate ions is maintained even during storage to improve the touch of clothes after washing, etc. Based on the amazing fact that you can continue to maintain the washing effect.
本発明は、さらに、粉末洗剤を製造するために酸と塩基との中和反応を用いることができるという事実に基づく。所定の中和反応の場合、発生する熱を用いて乾燥させると同時に、中和反応で粒子の内部に形成されたガスが作る空隙によって粉末洗剤、望ましくは低密度粉末洗剤を製造することができる。 The invention is further based on the fact that an acid and base neutralization reaction can be used to produce a powder detergent. In the case of a given neutralization reaction, it is possible to produce a powder detergent, preferably a low-density powder detergent, by drying using heat generated and at the same time by the voids created by the gas formed inside the particles by the neutralization reaction. .
本発明は、（ａ）酸性形態の水溶性高分子０．１ないし１５重量部、（ｂ）陰イオン性界面活性剤５ないし２０重量部、（ｃ）アルカリビルダー１０ないし７０重量部、及び（ｄ）前記アルカリビルダーと隔離されるようにコーティングされた有機酸０．５ないし２０重量部を含むことを特徴とする、洗濯後の衣類の肌触りを向上させ、色相衣類の色が褪せることを防止することができる粉末洗剤組成物を提供する。 The present invention includes (a) 0.1 to 15 parts by weight of a water-soluble polymer in acidic form, (b) 5 to 20 parts by weight of an anionic surfactant, (c) 10 to 70 parts by weight of alkali builder, and ( d) It includes 0.5 to 20 parts by weight of an organic acid coated so as to be isolated from the alkali builder, thereby improving the touch of the clothes after washing and preventing the color of the hue clothes from fading. A powder detergent composition is provided.
本発明の明細書に使われた用語「肌触り」とは、洗濯の後、人が衣類を着たり触る際の感じであって、通常Ｋａｗａｂａｔａ ｓｙｓｔｅｍで測定された値で表すことができる
。この測定値は、人が肌触りを感じるときの満足度と相関性があると知られており、衣類の肌触りを評価する際によく使われる測定システムである。
The term “texture” used in the specification of the present invention is a feeling when a person wears or touches clothes after washing, and can be represented by a value usually measured by Kawabata system. This measurement value is known to have a correlation with satisfaction when a person feels the touch, and is a measurement system often used when evaluating the touch of clothing.
本発明の粉末洗剤組成物は、（ａ）酸性形態の水溶性高分子０．１ないし１５重量部を含む。望ましい酸性形態の水溶性高分子としては、アクリル酸重合体、マレイン酸重合体、メチルメタクリル酸重合体、α−ヒドロキシ酸重合体、テトラメチレン‐１，２‐ジカルボン酸重合体、４‐メトキシテトラメチレン１，２‐ジカルボン酸重合体、及びこれらの共重合体からなる群より選択されたいずれか１つ以上を使うことができる。本発明の望ましい一実施例において、酸性形態の水溶性高分子はカルボン酸などが酸性形態で重合体の側鎖に繋がれているため、塩基性物質と反応して中和されながら粉末洗剤の粒子を形成する長所がある。また、高分子の形態で水分が消失される場合、その高分子の物理的特性によって形態が維持されるため、中和反応によって発生したガスによって生じた空隙の骨格がそのまま維持されることができる。また、酸性形態の水溶性高分子は高分子の０．１％（ｗ／ｗ）水溶液のｐＨが１ないし３であることが望ましい。 The powder detergent composition of the present invention comprises (a) 0.1 to 15 parts by weight of a water-soluble polymer in an acidic form. Desirable acidic water-soluble polymers include acrylic acid polymer, maleic acid polymer, methylmethacrylic acid polymer, α-hydroxy acid polymer, tetramethylene-1,2-dicarboxylic acid polymer, 4-methoxytetra Any one or more selected from the group consisting of a methylene 1,2-dicarboxylic acid polymer and a copolymer thereof can be used. In a preferred embodiment of the present invention, since the water-soluble polymer in the acidic form has a carboxylic acid or the like linked to the side chain of the polymer in the acidic form, it reacts with a basic substance to neutralize the powder detergent. Has the advantage of forming particles. In addition, when water is lost in the form of a polymer, the form is maintained by the physical characteristics of the polymer, so that the void skeleton generated by the gas generated by the neutralization reaction can be maintained as it is. . The acidic form of the water-soluble polymer preferably has a pH of 1 to 3 in a 0.1% (w / w) aqueous solution of the polymer.
さらに、本発明の粉末洗剤組成物は、（ｂ）陰イオン性界面活性剤５ないし２０重量部を含む。この陰イオン性界面活性剤は、洗浄、すなわち、洗剤本来の役割を果たすだけでなく、前記の酸性形態の水溶性高分子と共に、後述するアルカリビルダーと中和反応することにより、粉末洗剤に空隙を形成する役割も果たす。陰イオン性界面活性剤としては、通常洗濯洗剤組成物に使われる陰イオン性界面活性剤を使うことができる。陰イオン性界面活性剤としては、具体的にラウリルベンゼンスルホン酸、α−オレフィンスルホン酸塩、ラウリル硫酸ナトリウム、ラウリルエーテル硫酸ナトリウム、及びこれらの混合物などを使うことができる。望ましくは、陰イオン性界面活性剤として物性が良好であって粉末洗剤の密度を低めることができるラウリルベンゼンスルホン酸が使われる。粉末洗剤組成物の所望の密度に応じて、含まれる含量を前述した範囲内で適切に調節することができる。 Further, the powder detergent composition of the present invention comprises (b) 5 to 20 parts by weight of an anionic surfactant. This anionic surfactant not only functions as a cleaning agent, that is, the detergent itself, but also neutralizes with the alkali builder described later, together with the water-soluble polymer in the acidic form, so that a void is formed in the powder detergent. Also plays the role of forming. As an anionic surfactant, the anionic surfactant normally used for a laundry detergent composition can be used. Specific examples of the anionic surfactant include lauryl benzene sulfonic acid, α-olefin sulfonate, sodium lauryl sulfate, sodium lauryl ether sulfate, and mixtures thereof. Desirably, lauryl benzene sulfonic acid is used as the anionic surfactant because it has good physical properties and can reduce the density of the powder detergent. Depending on the desired density of the powder detergent composition, the content contained can be adjusted appropriately within the aforementioned range.
また、本発明の粉末洗剤組成物は、（ｃ）アルカリビルダー１０ないし７０重量部を含む。アルカリビルダーとしては、炭酸ナトリウム（ソーダ灰）、重炭酸ナトリウム（重炭酸ソーダ）、硫酸ナトリウム（硫酸ソーダ）、及びこれらの混合物を使うことができる。通常粉末洗剤に使われるアルカリビルダーは、適切に組み合わせることで粉末洗剤のｐＨが高くなることを防止することができるため、高いｐＨによって高温洗濯の際に発生し得る衣類の移染が発生する可能性を減らすことができる。本発明においては、前述した役割の他に酸性形態の水溶性高分子及び陰イオン性界面活性剤と中和反応を起こす役割も果た
す。特に、アルカリビルダーの含量によって形成される粉末洗剤組成物の密度に差が生じることがあるため、これらの含量を適切に調節して粉末洗剤の密度を調節することができる。すなわち、前述のように、酸性形態の水溶性高分子および陰イオン性界面活性剤のような酸性物質と、アルカリビルダーのようなアルカリ性物質との間の中和反応により生成される二酸化炭素および水分などのガスにより発生した気泡から空隙が形成され、これら空隙の増大によって粉末洗剤組成物を冷水における溶解性に優れて洗濯時に残留物が残らない低密度に製造することができる。
Moreover, the powder detergent composition of this invention contains (c) 10-70 weight part of alkali builders. As an alkali builder, sodium carbonate (soda ash), sodium bicarbonate (sodium bicarbonate), sodium sulfate (sodium sulfate), and a mixture thereof can be used. Alkaline builder, which is usually used for powder detergents, can prevent the pH of powder detergents from becoming high by combining them appropriately. Therefore, high pH can cause the transfer of clothes that can occur during high-temperature washing. Sex can be reduced. In the present invention, in addition to the above-mentioned role, it also plays a role in causing a neutralization reaction with the water-soluble polymer and the anionic surfactant in the acidic form. In particular, since the density of the powder detergent composition formed may vary depending on the content of the alkali builder, the density of the powder detergent can be adjusted by appropriately adjusting these contents. That is, as described above, carbon dioxide and water generated by a neutralization reaction between an acidic substance such as a water-soluble polymer in an acidic form and an anionic surfactant and an alkaline substance such as an alkali builder. Voids are formed from bubbles generated by gas such as, and by increasing these voids, the powder detergent composition can be manufactured to a low density with excellent solubility in cold water and no residue remaining during washing.
さらに、本発明の粉末洗剤組成物は、（ｄ）前記アルカリビルダーと隔離されるようにコーティングされた有機酸０．５ないし２０重量部を含む。本発明の粉末洗剤組成物は、硬水軟化剤として通常使われる不溶性のゼオライトの代りにイオン封入能力のある、水に溶解され易い有機酸を含む。本発明の組成物において使われた有機酸は、水溶性であるため硬水の軟水化速度が非常に速くて洗濯後の衣類に炭酸カルシウムなどが残存する可能性が非常に少ないだけでなく、硬水軟化剤そのものが洗濯後の衣類に残存する可能性が少なくて洗濯後の衣類の肌触りを非常に向上させ、炭酸カルシウム及びゼオライトが色相衣類に付着して色が褪せることを防止することができる。また、有機酸は洗剤組成物のｐＨを低め、高いｐＨによって高温洗濯の際に発生し得る衣類の移染の可能性を減らすことができる。 Further, the powder detergent composition of the present invention comprises (d) 0.5 to 20 parts by weight of an organic acid coated so as to be isolated from the alkali builder. The powder detergent composition of the present invention contains an organic acid which is easily soluble in water and has an ion encapsulating ability instead of the insoluble zeolite which is usually used as a hard water softener. Since the organic acid used in the composition of the present invention is water-soluble, the water softening speed of hard water is very high, and the possibility that calcium carbonate or the like remains in the clothes after washing is very low. The softening agent itself is less likely to remain in the clothes after washing, and the touch of the clothes after washing is greatly improved, and it is possible to prevent calcium carbonate and zeolite from adhering to the hue clothes and fading the color. Also, the organic acid can lower the pH of the detergent composition and reduce the likelihood of garment transfer that may occur during high temperature washing due to the high pH.
本発明の粉末洗剤組成物に含有された有機酸は、水溶性多価カルボン酸からなる無水クエン酸、含水クエン酸、ＥＤＴＡ、Ｎ‐ヒドロキシエチレンジアミン三酢酸、ニトリロ三酢酸 、１，３‐プロピレンジアミン四酢酸、コハク酸、フマル酸、マレイン酸、１，２
，３，４‐シクロペンタン四酢酸、Ｏ‐カルボキシメチルタルトロン酸、Ｏ‐カルボキシメチルオキシコハク酸、酒石酸、グルタミン酸などのイオン封入力のある物質を使うことができるが、これに限定されない。
The organic acid contained in the powder detergent composition of the present invention is an anhydrous citric acid composed of a water-soluble polyvalent carboxylic acid, hydrous citric acid, EDTA, N-hydroxyethylenediamine triacetic acid, nitrilotriacetic acid, 1,3-propylenediamine. Tetraacetic acid, succinic acid, fumaric acid, maleic acid, 1,2
, 3,4-cyclopentanetetraacetic acid, O-carboxymethyltartronic acid, O-carboxymethyloxysuccinic acid, tartaric acid, glutamic acid, and other substances having an ion-sealing input can be used, but are not limited thereto.
本発明の望ましい一実施例において、粉末洗剤組成物に含有された有機酸は酸性形態であるため、洗剤組成物のアルカリ成分と適切に隔離されなければならない。適切に隔離されない場合、空気中の水分と共に反応してケーキングを形成し、これによって洗浄効果を低下させる恐れがある。したがって、隔離された有機酸を使う場合、粉末洗剤組成物の保管中の安定性を改善することができ、これによって粉末洗剤組成物の洗浄力を保管中にも維持することができる。酸性成分とアルカリ成分とを隔離する方法としては、本発明が属した分野で通常用いられる方法を使用することができる。本発明の粉末洗剤組成物は、アルカリ成分と隔離できるようにコーティングされた有機酸を含む。本明細書で使われた用語「コーティング」とは、前述した有機酸がコーティング物質によって洗剤組成物のアルカリ成分と分離されるようにコーティング物質で包まれているか、または混合されていることを意味する。本発明のコーティングされた有機酸は、望ましくはアルカリ成分との接触を遮断できるように完全にコーティングされるものであるが、本発明の目的を阻害しない範囲内であればアルカリ成分と完全に隔離される必要はない。すなわち、本発明は組成物内のアルカリ成分との接触がより少なくなるように操作または処理された有機酸を含む粉末洗剤組成物を含む。コーティングされた有機酸のコーティング厚さは、粉末洗剤組成物の保管中の安定性及び洗濯時の洗浄力を考慮すれば３ないし５０ｕｍであることがさらに望ましい。 In a preferred embodiment of the present invention, the organic acid contained in the powder detergent composition is in an acidic form and must be adequately separated from the alkaline components of the detergent composition. If not properly sequestered, it can react with moisture in the air to form caking, thereby reducing the cleaning effect. Thus, when using isolated organic acids, the stability of the powder detergent composition during storage can be improved, thereby maintaining the cleaning power of the powder detergent composition during storage. As a method for separating the acidic component from the alkaline component, a method usually used in the field to which the present invention belongs can be used. The powder detergent composition of the present invention comprises an organic acid coated so as to be separable from the alkaline component. As used herein, the term “coating” means that the organic acid described above is wrapped in or mixed with a coating material so that it is separated from the alkaline components of the detergent composition by the coating material. To do. The coated organic acid of the present invention is desirably completely coated so as to be able to block contact with the alkaline component, but is completely separated from the alkaline component as long as it does not interfere with the object of the present invention. There is no need to be done. That is, the present invention includes a powder detergent composition comprising an organic acid that has been manipulated or treated to have less contact with alkaline components in the composition. The coating thickness of the coated organic acid is more preferably 3 to 50 um in consideration of the stability during storage of the powder detergent composition and the detergency during washing.

物を使う場合、比重が０．０５ないし０．５ｇ／ｍｌであるシリカ化合物を使うことが望ましく、ＤＯＰ吸収価が２００ｍｌ／１００ｇ以上であるものを使うことがさらに望ましい。
As a coating material for coating the organic acid of the present invention, silica compounds, porous starch decomposition products, polyvinyl pyrrolidone, carboxymethyl cellulose, and the like can be used. When using a silica compound, there is an advantage that the fluidity of the particles is improved so that the particles do not aggregate even for long-term storage. When using polyvinylpyrrolidone, there is no need to add a dye transfer inhibitor separately. There is. In addition, the porous starch decomposition product has an advantage of being completely dissolved in water and an advantage of having a function of preventing redeposition of dirt. When a silica compound is used as the coating material, it is preferable to use a silica compound having a specific gravity of 0.05 to 0.5 g / ml, and more preferably a DOP absorption value of 200 ml / 100 g or more.
本発明の望ましい一実施例において、有機酸を効果的に隔離するために有機酸をコーティングする前にバインダー物質で予め処理することができる。例えば、有機酸をバインダー物質と十分混合して有機酸の周りが十分コーティングされたとき、これらの外部を前述したシリカ化合物などのコーティング物質でコーティングして本発明のコーティングされた有機酸を製造することができる。 In a preferred embodiment of the invention, it can be pre-treated with a binder material prior to coating the organic acid to effectively sequester the organic acid. For example, when the organic acid is sufficiently mixed with the binder material and the periphery of the organic acid is sufficiently coated, the outside is coated with a coating material such as the above-described silica compound to produce the coated organic acid of the present invention. be able to.
バインダー物質は、非イオン界面活性剤、ポリエチレングリコールなどのような親水性物質及び／またはシリコン化合物、脂肪酸などのような疎水性物質を使うことができる。望ましくは、エチレンオキサイド付加モル数が５ないし２０モルであるアルキルエトキシレート、エチレンオキサイド付加モル数が４００ないし２０，０００であるポリエチレングリコール及びシリコン化合物からなる群より選択されたいずれか１つ以上をバインダー物質として使うことができる。シリコン化合物を使う場合、消泡剤の成分を別に使う必要がないという長所がある。 The binder material may be a nonionic surfactant, a hydrophilic material such as polyethylene glycol, and / or a hydrophobic material such as a silicon compound or a fatty acid. Desirably, at least one selected from the group consisting of alkyl ethoxylates having an ethylene oxide addition mole number of 5 to 20 moles, polyethylene glycol having an ethylene oxide addition mole number of 400 to 20,000, and a silicon compound. Can be used as a binder material. When using a silicon compound, there is an advantage that it is not necessary to use an antifoaming component separately.
また、本発明の粉末洗剤組成物は、非イオン性界面活性剤５ないし２０重量部をさらに含むこともできる。通常使われる非イオン性界面活性剤は液状形態であるため、それらの全体含量によって粉末洗剤の密度に密接な影響を及ぼす。含量が高い場合には製造容易性が低下し、含量が低い場合には洗浄力が減少するため、前述した５ないし２０重量部を含むことが望ましい。非イオン性界面活性剤としては、通常洗濯洗剤組成物に使われる非イオン性界面活性剤を使うことができ、例えばポリオキシエチレンアルキルエーテル、ココナッツジエタノールアミド、脂肪酸アルカノールアミン、アミンオキサイド、アルキルポリグルコシド、メチルポリエチレンアルキルエーテル、糖エーテルなどを使うことができる。 The powder detergent composition of the present invention may further include 5 to 20 parts by weight of a nonionic surfactant. Since commonly used nonionic surfactants are in liquid form, their total content has a close influence on the density of the powder detergent. When the content is high, manufacturability is lowered, and when the content is low, the detergency is reduced. Therefore, it is desirable to include 5 to 20 parts by weight as described above. As the nonionic surfactant, a nonionic surfactant usually used in laundry detergent compositions can be used, for example, polyoxyethylene alkyl ether, coconut diethanolamide, fatty acid alkanolamine, amine oxide, alkylpolyglucoside. , Methyl polyethylene alkyl ether, sugar ether, etc. can be used.
さらに、本発明の粉末洗剤組成物は、本発明の目的を阻害しない範囲内で粉末洗剤粒子の剤形化に役立つように水不溶性硬水軟化剤を含むこともできる。硬水軟化剤としては、通常使われているゼオライトを使うことができ、粒子が小さいＰ型ゼオライトを使うことが衣類残留性の側面から望ましい。但し、ゼオライトの残留を最小化しなければ肌触りの良い結果ができないため、これらゼオライトの含量は最小の量で使うことが望ましい。 Furthermore, the powder detergent composition of the present invention may also contain a water-insoluble hard water softener so as to assist in the formulation of powder detergent particles within the range not impairing the object of the present invention. As the water softener, commonly used zeolite can be used, and it is desirable from the viewpoint of clothing persistence to use P-type zeolite with small particles. However, it is desirable to use these zeolites in the minimum amount, since the result cannot be touched unless the residual zeolite is minimized.
また、本発明の粉末洗剤組成物は、本発明の目的を阻害しない限りその他の種々の添加剤０．３ないし１０重量部をさらに含むこともできる。その他の添加剤としては、タンパク質汚れを除去するためのタンパク質分解酵素（プロテアーゼなど）、脂質汚れを除去するための脂質分解酵素（リパーゼなど）、食べ物汚れを除去するための炭水化物分解酵素（アミラーゼなど）、綿繊維の毛羽を除去するためのセルロース分解酵素（セルラーゼなど）、ビフェニル系、スチルベン系などの蛍光染料及び繊維から染み出る染料が他の繊維に付着することを防止したり、脱離された汚れが再付着することを防止する移染防止剤などの成分を付け加えて含むこともできる。タンパク質分解酵素、脂質分解酵素、炭水化物分解酵素、及びセルロース分解酵素はそれぞれ０．０１ないし１重量部含有することが望ましく、蛍光染料は０．１ないし１重量部含有することが望ましく、移染防止剤は０．５ないし５重量部含有することが望ましい。 Moreover, the powder detergent composition of the present invention may further contain 0.3 to 10 parts by weight of various other additives as long as the object of the present invention is not impaired. Other additives include proteolytic enzymes (proteases, etc.) to remove protein stains, lipolytic enzymes (lipases, etc.) to remove lipid stains, and carbohydrate-degrading enzymes (amylase, etc.) to remove food stains ), Cellulose-degrading enzymes (cellulases, etc.) to remove fluff from cotton fibers, fluorescent dyes such as biphenyl and stilbene, and dyes that exude from fibers are prevented from adhering to other fibers or detached. Ingredients such as a dye transfer inhibitor that prevents the soil from re-adhering can also be included. Proteolytic enzyme, lipolytic enzyme, carbohydrate-degrading enzyme, and cellulose-degrading enzyme are each preferably contained in an amount of 0.01 to 1 part by weight, and the fluorescent dye is preferably contained in an amount of 0.1 to 1 part by weight to prevent dye transfer. It is desirable to contain 0.5 to 5 parts by weight of the agent.
本発明は、さらに、別の乾燥工程を必要とすることなく粉末洗剤組成物を製造することができる製造方法を、望ましくは低密度粉末洗剤組成物を製造することができる製造方法を提供する。本発明の明細書で使われた用語「低密度」とは、粒子間の空隙を含む見掛け密度が０．６ｇ／ｍｌ以下であることを意味する。本発明は、酸成分と塩基成分との中和
反応で発生する熱によって乾燥される粉末洗剤組成物の製造方法であって、別の乾燥工程がなく、（Ｓ１）酸成分として酸性形態の水溶性高分子及び陰イオン性界面活性剤を、塩基成分としてアルカリビルダーを調製する工程と、（Ｓ２）前記酸性形態の水溶性高分子０．１ないし１５重量部及び陰イオン性界面活性剤５ないし２０重量部をアルカリビルダー１０ないし７０重量部と共に混合機に投入する工程と、（Ｓ３）前記混合機に投入された（Ｓ２）工程の成分を均一に混合する工程と、（Ｓ４）予め製造されたコーティングされた有機酸を混合する工程と、を含むことを特徴とする粉末洗剤組成物の製造方法を提供する。
The present invention further provides a production method capable of producing a powder detergent composition without requiring a separate drying step, desirably a production method capable of producing a low density powder detergent composition. The term “low density” used in the specification of the present invention means that the apparent density including voids between particles is 0.6 g / ml or less. The present invention is a method for producing a powder detergent composition that is dried by heat generated by a neutralization reaction between an acid component and a base component, and does not have a separate drying step. A step of preparing an alkali builder with a basic polymer and an anionic surfactant as a base component, and (S2) 0.1 to 15 parts by weight of the water-soluble polymer in the acidic form and an anionic surfactant 5 to A step of adding 20 parts by weight to the mixer together with 10 to 70 parts by weight of the alkali builder, (S3) a step of uniformly mixing the components of the step (S2) input to the mixer, and (S4) pre-manufactured And a step of mixing the coated organic acid, and a method for producing a powder detergent composition.
本発明は、粉末洗剤を製造するために酸と塩基との中和反応を用いて粉末洗剤を粒子化させ、所定の中和反応の場合に発生する熱を用いて乾燥させると同時に中和反応で粒子内部に形成されたガスが作る空隙によって粉末洗剤が製造される原理を用いる。このような空隙は溶解性（特に冷水での溶解性）を改善させ、洗濯時の残留物が残らないようにする長所がある。上述のように、本発明の製造方法は、従来の低密度粉末洗剤組成物の製造方法と異なって、粉末を乾燥させる加熱工程を必要としないので、非常に簡単かつ経済的である。すなわち、低密度粉末洗剤の製造のために、向流式噴霧乾燥装置、スチーム噴射ミキサー機などの装置を使う必要がない。 In the present invention, in order to produce a powder detergent, the powder detergent is made into particles using a neutralization reaction between an acid and a base, and is dried using heat generated in the case of a predetermined neutralization reaction, and at the same time a neutralization reaction The principle that powder detergent is produced by the voids created by the gas formed inside the particle is used. Such voids have the advantage of improving the solubility (especially the solubility in cold water) and leaving no residue during washing. As described above, the production method of the present invention is very simple and economical because it does not require a heating step for drying the powder, unlike the conventional method for producing a low density powder detergent composition. That is, it is not necessary to use a device such as a counter-current spray dryer or a steam spray mixer for the production of a low-density powder detergent.
以下、本発明をより具体的に説明するために実施例などを挙げて説明する。しかし、本発明による実施例は種々の他の形態に変形することができ、本発明の範囲が以下で詳述する実施例に限定されると解釈されてはならない。 Hereinafter, in order to describe the present invention more specifically, examples will be described.

安定性評価
本発明の粉末洗剤組成物において、コーティングされた有機酸は経時後にも安定した状態で存在することができるか否かを評価するため、コーティングされた有機酸をソーダ灰と混合してから、経時後に、ケーキングが発生するか否かを評価した。ソーダ灰は、洗剤成分中の代表的なアルカリ物質であって酸／塩基反応を起こすことができる主要物質である。ソーダ灰と混合しても経時後ケーキングが発生しなければ、ケーキングが防止される安定した物質と判断される。したがって、本発明においては実施例１の予め製造されたコーティングされた有機酸とソーダ灰パウダーとを１：３の割合、すなわち１００ｇのコーティングされた有機酸と３００ｇのソーダ灰とを混合してから、３０℃、相対湿度６０％の恒温恒湿器に１週間放置後、１２ｍｅｓｈ不通過分に対する含量を測定してケーキングの形成程度を確認した。本実験の比較実験のため、コーティングされない有機酸１００ｇとソーダ灰３００ｇとを同じ条件にして投入した。実験結果を表２に示した。
Stability Evaluation In the powder detergent composition of the present invention, in order to evaluate whether the coated organic acid can exist in a stable state even after aging, the coated organic acid is mixed with soda ash. From the above, it was evaluated whether or not caking occurred after lapse of time. Soda ash is a typical alkaline substance in detergent components and is the main substance capable of causing an acid / base reaction. If no caking occurs after aging even when mixed with soda ash, it is judged as a stable substance that prevents caking. Therefore, in the present invention, the previously prepared coated organic acid of Example 1 and soda ash powder are mixed in a ratio of 1: 3, ie, 100 g of coated organic acid and 300 g of soda ash. After standing for 1 week in a constant temperature and humidity chamber at 30 ° C. and 60% relative humidity, the content of the 12 mesh non-passing portion was measured to confirm the degree of caking formation. For comparison experiment of this experiment, 100 g of uncoated organic acid and 300 g of soda ash were added under the same conditions. The experimental results are shown in Table 2.
表２に示されるように、コーティングされない有機酸はソーダ灰と反応し、ケーキングが形成され合って塊が大きくなる現象が発生して１２ｍｅｓｈ不通過分が相対的に多く発
生することが分かる。上記の例において、１２ｍｅｓｈ不通過分が１０％未満に発生する場合には、実際製品に適用された場合に安定したものと判断された。
As shown in Table 2, it can be seen that the uncoated organic acid reacts with soda ash, and a phenomenon in which caking is formed and the lump is enlarged occurs, and a relatively large 12 mesh non-passing portion is generated. In the above example, when the 12 mesh non-passage occurred in less than 10%, it was determined to be stable when applied to an actual product.
肌触り評価
前記実施例２、３及び比較例１、２で製造した粉末洗剤組成物に対して一般に消費者が実施するドラムタイプの洗濯条件（洗濯温度：４０℃、洗濯時間：４０分、すすぎ：３回、洗濯量：３Ｋｇ、洗剤量：３５ｇ、試験布：縦×横＝１２０ｃｍ×９０ｃｍ（韓国衣類試験研究院標準綿布）２枚）で洗濯力を評価した後、試験布をＫａｗａｂａｔａ ｓｙｓ

Touch Evaluation Drum-type washing conditions (washing temperature: 40 ° C., washing time: 40 minutes, rinsing) generally performed by consumers on the powder detergent compositions produced in Examples 2 and 3 and Comparative Examples 1 and 2 Washing capacity: 3 times, washing amount: 3 kg, detergent amount: 35 g, test cloth: length x width = 120 cm x 90 cm (2 pieces of standard cotton cloth of Korea Clothing Research Institute), and then the test cloth is Kawabata sys
Measured items of tem, KOSHI (Stiffness), SHARI (Crispness), FUKURAMI (Fullness and softness), and HARI (Anti-drap stuffness = spreading) are measured and input to summer formulas for men and women. As a result, Total Hand Value shown in Table 3 was obtained.
表３から分かるように、Ｔ．Ｈ．Ｖ．において実施例が比較例より良好な値を示した。一般に、実際に消費者が５点を満点として肌触りを評価して測定した値とＫａｗａｂａｔａ Ｓｙｓｔｅｍの測定結果である Ｔ．Ｈ．Ｖ．は相関性があると認められている。このような肌触りの変化は、本発明の粉末洗剤組成物が、ゼオライトなどの水不溶性物質が衣類に残留したり炭酸カルシウムが衣類に付着することが少なく、組成物のｐＨが低いためであると判断される。 As can be seen from Table 3, T.W. H. V. In Example, the example showed a better value than the comparative example. In general, the values actually measured by consumers by evaluating the touch with 5 points being the perfect score and the measurement results of Kawabata System H. V. Are recognized to be correlated. Such a change in touch is because the powder detergent composition of the present invention has a low pH of the composition because water-insoluble substances such as zeolite hardly remain in clothing or calcium carbonate adheres to clothing. To be judged.
洗浄力評価
洗剤の基本能力である洗浄力を評価した。洗浄力評価は同じ条件の洗濯機を使って評価し、一般水道水を使用した。洗濯時の条件は、肌触り評価と同じ条件（洗濯温度：４０℃、洗濯時間：４０分、すすぎ：３回、洗濯量：３Ｋｇ、洗剤量：３５ｇ、試験布：縦×横＝１２０ｃｍ×９０ｃｍ（韓国衣類試験研究院標準綿布）２枚）にし、洗浄力評価のために使った汚染布は日本洗濯科学協会で製造した人工湿式汚染布を使って５×５ｃｍ大きさの汚染布２０枚に対して評価を実施した。これら汚染布の白色度を示す値であるＷＢ値を洗濯前及び洗濯後に色差計を用いて測定した。前記実施例及び比較例で製造したそれぞれの粉末洗剤組成物３５ｇを洗濯機に入れ、実際の綿Ｔシャツに汚染布を付着させて評価した。洗濯機の標準コースで洗濯した後、脱水された汚染布を恒温恒湿室（２５℃、２０％ＲＨ）に１日間乾燥させてからアイロンをかけて同一色差計でＷＢ値を測定した。下記数式１に表されるクベルカ・ムンク（Ｋｕｂｅｌｋａ−Ｍｕｎｋ）式に代入して洗濯力を計算し、その結果を下記表４に示した。
Detergency evaluation Detergency, which is the basic ability of detergents, was evaluated. Detergency was evaluated using a washing machine under the same conditions, and general tap water was used. The conditions at the time of washing are the same conditions as the touch evaluation (washing temperature: 40 ° C., washing time: 40 minutes, rinsing: 3 times, washing amount: 3 Kg, detergent amount: 35 g, test cloth: length × width = 120 cm × 90 cm ( 2), and the soiled cloth used for the detergency evaluation is 20 artificial fabrics made by the Japan Laundry Science Association. The evaluation was conducted. The WB value, which is a value indicating the whiteness of these contaminated cloths, was measured using a color difference meter before and after washing. 35 g of each powder detergent composition produced in the above Examples and Comparative Examples was put in a washing machine and evaluated by attaching a contaminated cloth to an actual cotton T-shirt. After washing in the standard course of the washing machine, the dehydrated contaminated cloth was dried in a constant temperature and humidity chamber (25 ° C., 20% RH) for 1 day, then ironed, and the WB value was measured with the same color difference meter. The washing power was calculated by substituting into the Kubelka-Munk equation expressed by the following Equation 1, and the results are shown in Table 4 below.
前記数式１において、Ｒsは汚染布の表面反射率であって、Ｒcは汚染除去後の綿布の表面反射率であって、Ｒoは白色綿布の表面反射率である。 In Equation 1, the R s a surface reflectance of stained cloth, and R c a surface reflectance of the cotton fabric after decontamination, R o is the surface reflectance of the white cotton cloth.
表４から分かるように、実施例２、３で製造した粉末洗剤組成物は比較例１、２で製造した粉末洗剤組成物に比べて洗浄力が高く、これは酸性形態の水溶性高分子による汚染再付着防止機能と有機酸によるシナジー効果に因ると判断される。また、有機酸を使った本発明の組成物は、通常のゼオライトなどを用いた粉末洗剤組成物より溶解速度が速く、洗浄力が向上すると考えられる。 As can be seen from Table 4, the powder detergent compositions produced in Examples 2 and 3 have higher detergency than the powder detergent compositions produced in Comparative Examples 1 and 2, and this is due to the water-soluble polymer in the acidic form. It is judged to be due to the anti-contamination function and the synergy effect of organic acids In addition, the composition of the present invention using an organic acid is considered to have a faster dissolution rate and improved detergency than a powder detergent composition using ordinary zeolite or the like.
本発明による粉末洗剤組成物は、通常の水不溶性硬水軟化剤の代りにコーティングされた有機酸を使うことで、硬水の軟水化速度が非常に速くて洗濯後の衣類に炭酸カルシウムなどが付着する可能性が非常に少ないだけでなく、硬水軟化剤そのものが洗濯後の衣類に残存する可能性が少なく、洗濯後の衣類の肌触りを非常に向上させて色相衣類の本来の色を維持することができる。また、本発明による粉末洗剤組成物は、アルカリ成分と有機酸との接触を防止することで、保管中の中和反応を遮断してケーキングが発生する現象を防止することができて安定的であり、洗浄力を保管中にも維持することができる。さらに、本発明の製造方法は、粉末洗剤の製造のために別の乾燥工程を必要としないだけでなく、簡単かつ経済的であって低密度粉末洗剤の製造に容易である。 The powder detergent composition according to the present invention uses a coated organic acid instead of the usual water-insoluble hard water softener, so that the water softening speed of hard water is very fast and calcium carbonate or the like adheres to clothes after washing. Not only is the possibility very low, but the water softener itself is less likely to remain in the clothes after washing, which can greatly improve the feel of the clothes after washing and maintain the original color of the hue clothes it can. In addition, the powder detergent composition according to the present invention is stable because it prevents the occurrence of caking by blocking the neutralization reaction during storage by preventing the contact between the alkali component and the organic acid. Yes, cleaning power can be maintained even during storage. Furthermore, the production method of the present invention does not require a separate drying step for the production of a powder detergent, but is simple and economical and easy to produce a low density powder detergent.
