Description
本発明は、衣料用粉末洗剤組成物に関する。 The present invention relates to a powder detergent composition for clothing.
洗濯に用いられる従来の衣料用粉末洗剤組成物では、主成分である界面活性剤１２〜４０％程度とともに、洗浄補助成分として多価金属イオン捕捉ビルダーが１０〜３０％程度配合されているものが大部分であった。多価金属イオン捕捉ビルダーとしては、アルミノケイ酸塩、結晶性シリケート、リン酸塩等の無機化合物、カルボン酸系高分子化合物等の有機化合物から選ばれるものが用いられるが、それらの中には環境に対する負荷が高いものが多い。 In the conventional powder detergent composition for clothes used for washing, there are those in which about 10 to 30% of a polyvalent metal ion trapping builder is blended as a cleaning auxiliary component together with about 12 to 40% of a surfactant as a main component. Mostly. As the polyvalent metal ion capture builder, those selected from inorganic compounds such as aluminosilicates, crystalline silicates, phosphates, and organic compounds such as carboxylic acid polymer compounds are used. There are many things with high load.
今後ますます深刻化する環境問題に対しては、被洗浄物の汚れの実態をふまえ、これまでにも増して、より環境に配慮した、環境への負荷の低い洗剤を設計することが求められるようになってきている。洗剤による環境への負荷低減といった点については、１９８０年代に湖沼の富栄養化問題から、それまで大量に使用されてきたトリポリリン酸ソーダをゼオライト（結晶性アルミノケイ酸塩）に転換し、リン酸塩を排除してきたことは周知の通りである。しかし、ゼオライトは十分な多価金属イオン捕捉能を得るために、一般に、洗剤組成のかなりの比率を占める量で用いられており、長年の使用による環境中への堆積について懸念する意見があった。 For environmental problems that will become more serious in the future, it will be necessary to design more environmentally friendly and less environmentally friendly detergents based on the actual condition of dirt on the object to be cleaned. It has become like this. In terms of reducing the environmental impact of detergents, in the 1980s, due to the eutrophication problem of lakes, sodium polypolyphosphate that had been used in large quantities until then was converted to zeolite (crystalline aluminosilicate) and phosphates. It is well known that the above has been excluded. However, zeolite is generally used in an amount that accounts for a significant proportion of the detergent composition in order to obtain sufficient multivalent metal ion scavenging capacity, and there have been concerns about deposition in the environment over many years of use. .
アルミノケイ酸塩、リン酸塩を低減した組成物の試みとして、特許文献１〜３の組成物が知られているが、洗浄力、泡立ち、泡切れといった基本性能は何れも満足のいくレベルではない。とりわけ、高硬度の洗濯水を用いる場合には、ビルダー成分を低減すると、優れた洗浄力、泡立ち、泡切れを実現することは困難であった。 As a trial of a composition having reduced aluminosilicate and phosphate, the compositions of Patent Documents 1 to 3 are known, but the basic performances such as detergency, foaming, and foaming are not satisfactory levels. . In particular, when using high-hardness washing water, it has been difficult to achieve excellent detergency, foaming, and foam loss when the builder component is reduced.
一方、洗濯方法としては、大きく分けて手洗い洗濯と洗濯機洗濯の２種類がある。近年では洗濯機の普及により洗濯機洗濯が増加する傾向にあるが、汚れ落ちや経済性の観点から、依然、手洗い洗濯に対するニーズも多い。また、世界的にみても水資源の少ない地域では出来るだけ少ない水で洗濯できるように手洗い洗濯を採用する場合が多い。 On the other hand, there are two types of washing methods: hand washing and washing machine washing. In recent years, there has been a tendency for washing machine washing to increase due to the widespread use of washing machines, but there are still many needs for hand-washing washing from the viewpoint of stain removal and economic efficiency. In addition, hand washing is often employed so that washing can be performed with as little water as possible in regions where water resources are small in the world.
手洗い洗濯及び洗濯機洗濯、中でも手洗い洗濯においては、洗浄力に加え、洗浄時の泡立ちの豊かさ、及び洗浄後のすすぎのし易さが重要な課題である。特に水資源の少ない地域においては、すすぎ工程においてすばやく泡が消え、少量の水ですすぎが完了する洗濯が強く望まれる。しかしながら、すすぎを改善する場合は泡切れのよい界面活性剤を使用する必要があるが、このような界面活性剤を用いた場合、洗浄時の泡立ち性が大きく損なわれる。特に手洗い洗濯の場合、洗浄時に泡立ちが良くない場合は洗剤を足すケースもあることから、洗浄時の泡立ちの豊かさと洗浄後のすすぎのし易さの両立が重要な課題であった。特許文献４には、非イオン界面活性剤、特定の陰イオン界面活性剤、及び炭素数８〜１８の脂肪酸又はその塩を特定条件で含有する洗浄剤組成物が、洗浄時の洗浄力、及び泡立ち性が優れ、しかもすすぎ工程においてすばやく泡が消え、すすぎが速やかに完了する洗浄剤組成物であることが開示されている。なお、特許文献５にあるように、過炭酸塩、漂白活性化剤等を含有する漂白洗浄剤組成物に界面活性剤を配合することも知られている。 In hand-washing and washing machine washing, especially hand-washing, in addition to detergency, the richness of foaming during washing and the ease of rinsing after washing are important issues. Particularly in areas where water resources are scarce, washing is strongly desired in which the foam disappears quickly in the rinsing process and the rinsing is completed with a small amount of water. However, in order to improve rinsing, it is necessary to use a surfactant with good defoaming. However, when such a surfactant is used, the foamability during washing is greatly impaired. In particular, in the case of hand-washing, there are cases where detergent is added if foaming is not good at the time of washing. Therefore, it was an important issue to balance the richness of foaming during washing and the ease of rinsing after washing.

＜評価＞
（１）泡立ち性評価
モデル円形洗面器（底面の直径（内径）２５ｃｍ、高さ１５ｃｍの円柱のアクリル製容器）に、水温２０℃、炭酸カルシウム換算で１７９ｍｇ／Ｌ[ドイツ硬度で１０°DH]の硬水を〔塩化カルシウムＣａＣｌ2・２Ｈ2Ｏを１．５８ｇと硫酸マグネシウムＭｇＳＯ4・６Ｈ2Ｏを１．４５ｇにイオン交換水を加えて１０Ｌとしたもの、Ｃａ／Ｍｇ＝６／４（モル比）〕３Ｌ注入する。次に粉末洗剤組成物を（Ａ）成分が合計で７５０ｐｐｍになるように添加し、溶解させる。次いでそこに下記に示す調製油を加温（６０℃）して、３枚で１ｇになるように（１枚当り約０．３３ｇ）襟元にスポイド（φ：２ｍｍ）を用いて滴下した肌着を投じ、洗浄液に完全に浸る状態で１５分間放置する。放置後、肌着１枚に付き襟元を５０回もみ洗い（襟元同士を擦り合わせながら１往復（約１秒）で１回と換算）する。その後、肌着を取り出し、肌着の含水量が肌着に対して１００〜１４０％程度になるように洗面器から１０ｃｍ上で絞り、３枚絞った直後の泡高さを計測する。モデル円形洗面器を平面からみて４分割（扇形に４等分）したそれぞれの領域において、外側から水面からの泡高さをものさしなどを使用して、各領域につき１箇所、合計４箇所の泡高さの平均値を算出する。そして同様の評価を３名で行い、この３人の平均値を評価基準とした。
<Evaluation>
(1) Evaluation of foaming property In a model circular washbasin (a cylindrical acrylic container having a bottom diameter (inner diameter) of 25 cm and a height of 15 cm), a water temperature of 20 ° C., converted to calcium carbonate, 179 mg / L [German hardness: 10 ° DH] Hard water [1.58 g of calcium chloride CaCl 2 · 2H 2 O and 1.45 g of magnesium sulfate MgSO 4 · 6H 2 O to 10 L by adding ion-exchanged water, Ca / Mg = 6/4 (mol Ratio)] 3L injection. Next, the powder detergent composition is added and dissolved so that the total amount of the component (A) is 750 ppm. Next, the prepared oil shown below was heated (60 ° C.), and the underwear was dripped using a spoid (φ: 2 mm) on the neck so that 1 g per 3 sheets (about 0.33 g per sheet). Pour and leave for 15 minutes in a fully immersed solution. After leaving, the neck is attached to one undergarment and the neck is washed 50 times (converted to 1 time in one reciprocation (about 1 second) while rubbing the necks together). Thereafter, the underwear is taken out, and the height of the foam immediately after squeezing is reduced by 10 cm above the basin so that the moisture content of the underwear is about 100 to 140% of the underwear. In each area where the model circular washbasin is divided into 4 parts (divided into 4 parts in a fan shape) when viewed from the plane, using a measure of the height of the foam from the water surface from the outside, one area for each area, a total of 4 bubbles Calculate the average height. The same evaluation was performed by three persons, and the average value of these three persons was used as an evaluation standard.
洗い工程時の泡立ちが良くない場合は、視覚的に洗浄力不足と認知され、泡立ちをよくするために洗剤を足して泡を増やそうとするケースもある。そのために、一回辺りの洗剤の使用量が増加してしまうことがある。２５〜３９歳の中国人の女性（Ｎ＝２４）に泡立ちに関してアンケートを行った結果、泡高さが０．５ｃｍ以上の場合、３５％の女性が満足すると答え、１．０ｃｍ以上で８０％の女性が満足すると答え、１．５ｃｍ以上で９０％の女性が満足すると答えた。この結果から、洗浄時の泡高さは１．０ｃｍ以上が好ましく、１．３ｃｍ以上がより好ましく、１．６ｃｍ以上がより好ましい。 If foaming during the washing process is not good, it is visually perceived as insufficient cleaning power, and there are cases where detergent is added to increase foaming in order to improve foaming. For this reason, the amount of detergent used per time may increase. As a result of conducting a questionnaire on foaming to Chinese women aged 25 to 39 (N = 24), 35% of women answered that if the foam height is 0.5 cm or more, 80% if it is 1.0 cm or more Responded that 90% of women were satisfied at 1.5 cm or more. From this result, the bubble height during washing is preferably 1.0 cm or more, more preferably 1.3 cm or more, and more preferably 1.6 cm or more.

（２）すすぎ性評価
モデル円形洗面器（底面の直径（内径）２５ｃｍ、高さ１５ｃｍの円柱状のアクリル製容器）に、すすぎ水として、水温２０℃、炭酸カルシウム換算で１７９ｍｇ／Ｌ[ドイツ硬度で１０°DH]の硬水（前記泡立ち性評価で用いたものと同様に調製したもの）５Ｌを注入し、上記泡立ち性評価で絞った肌着３枚を投入する。肌着をすすぎ水中でほぐした後、ほぐした肌着を１枚ずつエリの部分を持って浴中から上に持ち上げ（浴中から洗面器上約５ｃｍの高さまで衣類全体が抜け切るまで持ち上げる）、その後再び浴中へ戻す。このような上下運動によるすすぎを１枚の肌着につき１０回繰り返した後、肌着の含水量が肌着に対して１００〜１４０％程度になるように洗面器から１０ｃｍ上で絞り、３枚の肌着のすすぎ、脱水が終わった直後のすすぎ水の状態を観察し、下記の基準でポイントをつけ、すすぎ性を評価した。
ポイント
６：液面全体を泡高さ１ｃｍ以上の泡が残っている。
５：液面全体に泡が残っている（１ｃｍ未満）。
４：液面の１／２程度に泡（１ｃｍ未満）が残っているか、またはすすぎ水が洗面器底面を確認できないほど濁っている。
３：液面の１／４程度に泡（１ｃｍ未満）が残っているか、またはすすぎ水が洗面器底面をようやく確認できる程度に濁っている。
２：液面に細かい泡が残っているが、すすぎ水が底面を確認できるほど透明である。
１：液面に泡が残っておらず、すすぎ水が底面を確認できるほど透明である。
(2) Rinsability evaluation In a model circular washbasin (cylindrical acrylic container having a bottom diameter (inner diameter) of 25 cm and a height of 15 cm), a rinse temperature of 20 ° C. and a calcium carbonate equivalent of 179 mg / L [German hardness] 10L DH] hard water (prepared in the same manner as used in the foaming evaluation) 5L is injected, and three pieces of underwear squeezed in the foaming evaluation are introduced. After rinsing the underwear in water, lift the loose underwear one by one by holding the Eli part up from the bath (lift from the bath to the height of about 5 cm above the basin until the entire clothing comes off), then Return to the bath again. After rinsing by such up-and-down movement 10 times for each undergarment, the water content of the undergarment is squeezed 10 cm above the basin so that the moisture content of the undergarment is about 100 to 140% of the undergarment. The state of the rinse water immediately after rinsing and dehydration was observed was pointed according to the following criteria, and the rinsing properties were evaluated.
Point 6: Bubbles with a bubble height of 1 cm or more remain on the entire liquid surface.
5: Bubbles remain on the entire liquid surface (less than 1 cm).
4: Foam (less than 1 cm) remains at about 1/2 of the liquid level, or the rinse water is so cloudy that the bottom of the basin cannot be confirmed.
3: Foam (less than 1 cm) remains at about 1/4 of the liquid level, or the rinsing water is cloudy enough to finally confirm the bottom of the basin.
2: Although fine bubbles remain on the liquid surface, the rinse water is so transparent that the bottom surface can be confirmed.
1: No bubbles remain on the liquid surface, and the rinse water is so transparent that the bottom surface can be confirmed.
すすぎ工程時の泡切れが良くなかったり、すすぎ水が濁っていると、泡が切れるかすすぎ水が明澄になるまで何度もすすぎを実施するために回数が増えてしまう。結果として、多量の水を消費してしまうことになる。このような観点からすすぎ時の泡が少なく、またすすぎ水が透明であることが好ましく、上記のポイントで３ポイント以下がより好ましく、さらに２ポイント以下が好ましい。 If the foaming during the rinsing process is not good or the rinsing water is cloudy, the number of times of rinsing is increased until the bubbles are cut or the rinsing water becomes clear. As a result, a large amount of water is consumed. From this point of view, it is preferable that there are few bubbles at the time of rinsing and the rinsing water is transparent, and the above point is more preferably 3 points or less, and further preferably 2 points or less.
