Description
本発明は、衣料用液体洗浄剤組成物に関する。 The present invention relates to a liquid detergent composition for clothing.
衣料用液体洗浄剤組成物には、当該組成物の洗浄能力のみならず審美性が良いことも求められる。 Liquid laundry detergent compositions are required to have not only good cleaning ability but also good aesthetics.
衣料用液体洗浄剤組成物の審美性を向上させるために、例えばパール光沢を付与することが行われている。パール光沢は、パール剤を液体洗浄剤組成物に混合させ、懸濁させることによって得ることができる。パール剤としては、雲母、オキシ塩化ビスマス、二酸化チタン等の無機物質や、魚のうろこ、高級脂肪酸類、脂肪酸グリコールエステル、脂肪酸アルカノールアミドの金属塩、ケトスルホネート等の有機化合物が知られているが、近年では、脂肪酸グリコールエステルが一般的である。 To improve the aesthetics of liquid detergent compositions for clothing, for example, a pearly luster has been imparted. Pearly luster can be obtained by mixing and suspending a pearling agent in the liquid detergent composition. Known pearling agents include inorganic substances such as mica, bismuth oxychloride, and titanium dioxide, and organic compounds such as fish scales, higher fatty acids, fatty acid glycol esters, metal salts of fatty acid alkanolamides, and ketosulfonates, but fatty acid glycol esters have become more common in recent years.
例えば脂肪酸グリコールエステルのパール剤は、常温で固体の微粒子であるため、経時的に懸濁液や液体洗浄剤組成物から分離する傾向がある。この問題の解決策として、例えば、乳化剤（特許文献１、２）、ベタイン、アルキル及び／又はアルケニルオリゴグリコシド（特許文献３）、レオロジー変性剤（特許文献４）を洗浄剤組成物に加えた組成物が開示されている。 For example, pearlescent agents made of fatty acid glycol esters are solid fine particles at room temperature and tend to separate over time from suspensions and liquid detergent compositions. As a solution to this problem, compositions have been disclosed in which, for example, emulsifiers (Patent Documents 1 and 2), betaine, alkyl and/or alkenyl oligoglycosides (Patent Document 3), and rheology modifiers (Patent Document 4) are added to detergent compositions.
しかしながら、パール剤を液体洗浄剤組成物に配合すると、パール剤が不均一に吐出され、すなわち分離安定性が低く、カーボンなどの無機汚れによる再汚染を防止する効果が低下することが見いだされた。
本発明は、分離安定性に優れ、且つ無機汚れによる再汚染防止性に優れた衣料用液体洗浄剤組成物を提供する。
However, it has been found that when a pearling agent is incorporated into a liquid detergent composition, the pearling agent is discharged unevenly, i.e., the separation stability is low, and the effect of preventing re-soiling by inorganic soils such as carbon is reduced.
The present invention provides a liquid detergent composition for clothing which has excellent separation stability and excellent anti-resoiling properties against inorganic soils.
本発明は、下記（ａ）成分を５質量％以上３０質量％以下、（ｂ）成分を０．０１質量％以上５質量％以下、（ｃ）成分を１質量％以上２０質量％以下、及び水を含有する衣料用液体洗浄剤組成物に関する。
（ａ）成分：界面活性剤（ただし（ｂ）成分は除く）
（ｂ）成分：パール剤
（ｃ）成分：水溶性無機金属塩
The present invention relates to a liquid detergent composition for clothing which contains the following component (a) in an amount of 5% by mass or more and 30% by mass or less: component (b) in an amount of 0.01% by mass or more and 5% by mass or less; component (c) in an amount of 1% by mass or more and 20% by mass or less; and water:
Component (a): Surfactant (excluding component (b))
Component (b): pearlescent agent Component (c): water-soluble inorganic metal salt
本発明によれば、分離安定性に優れ、且つ無機汚れによる再汚染防止性に優れた衣料用液体洗浄剤組成物が提供される。 The present invention provides a liquid detergent composition for clothing that has excellent separation stability and excellent resistance to re-soiling caused by inorganic soils.
本発明者らは、界面活性剤と特定のパール剤と水溶性無機塩とを組み合わせて用いることにより、分離安定性に優れ、且つ無機汚れによる再汚染防止性に優れた衣料用液体洗浄剤組成物が得られることを見いだした。この理由は明らかではないが、これらの成分を組み合わせることで、パール剤の分離が大幅に抑制され、パール剤が均一に吐出され、高濃度で衣類へ付着しないため、カーボンなどの無機汚れに対する再汚染防止能も良好になるものと推察される。 The inventors have discovered that by using a combination of a surfactant, a specific pearling agent, and a water-soluble inorganic salt, a liquid detergent composition for clothing that has excellent separation stability and excellent resistance to redeposition by inorganic stains can be obtained. The reason for this is unclear, but it is presumed that by combining these components, separation of the pearling agent is significantly suppressed, the pearling agent is discharged uniformly, and it does not adhere to clothing in high concentrations, resulting in good resistance to redeposition by inorganic stains such as carbon.

表１に示す成分を用いて実施例、比較例の衣料用液体洗浄剤組成物を製造した。得られた衣料用液体洗浄剤組成物について、以下の方法で分離安定性とカーボン再汚染防止能の評価を行った。
<Evaluation>
Liquid laundry detergent compositions of Examples and Comparative Examples were produced using the components shown in Table 1. The resulting liquid laundry detergent compositions were evaluated for separation stability and carbon redeposition prevention ability by the following methods.
＜分離安定性の評価＞
ガラス規格瓶（Ｎｏ．６規格、石田容器株式会社）にサンプルの衣料用液体洗浄剤組成物を５０ｇ充填し、４０℃で２か月静置した。保存後の外観の分離安定性を官能評価した。５名のパネラーが以下の基準で判定を行なった。５人の合計点から平均値を求め、表１に示した。
５：パール剤の分離がなく、組成物は全体的に光沢がある。
４：パール剤の分離が若干認められるが、組成物は全体的に光沢がある。
３：パール剤の分離は４よりも多くあるが、組成物は全体的に光沢がある。
２：パール剤が分離しており、組成物の一部に光沢が無い。
１：パール剤が完全に分離している。
<Evaluation of separation stability>
50 g of a sample of the liquid laundry detergent composition was filled into a standard glass bottle (No. 6 standard, Ishida Container Co., Ltd.) and allowed to stand at 40° C. for 2 months. The stability of the appearance after storage was evaluated by organoleptic evaluation. Five panelists judged according to the following criteria. The average score was calculated from the total scores of the five panelists and is shown in Table 1.
5: There is no separation of the pearlescent agent, and the composition is glossy overall.
4: Some separation of the pearlescent agent was observed, but the composition was glossy overall.
3: There is more separation of the pearlescent agent than in 4, but the composition is generally glossy.
2: The pearlescent agent is separated and some of the composition lacks luster.
1: The pearlescent agent is completely separated.
＜カーボン再汚染防止性の評価＞
（１）評価に使用する水
塩化カルシウム２水和物（富士フィルム和光純薬工業（株）製）９２．２５ｇ及び塩化マグネシウム６水和物（富士フィルム和光純薬工業（株）製）５４．５６ｇを１Ｌのイオン交換水で溶解させた原液を調製した（カルシウム／マグネシウム＝７／３（モル比））。得られた原液をイオン交換水１Ｌに対して１ｍＬ加えることで、ドイツ硬度５°ｄＨに調整し硬度水とした。以下の評価では特に断りがない限り、水はこの硬度水を用いた。
<Evaluation of Carbon Redeposition Prevention>
(1) Water used in evaluation 92.25 g of calcium chloride dihydrate (manufactured by Fujifilm Wako Pure Chemical Industries, Ltd.) and 54.56 g of magnesium chloride hexahydrate (manufactured by Fujifilm Wako Pure Chemical Industries, Ltd.) were dissolved in 1 L of ion-exchanged water to prepare a stock solution (calcium/magnesium = 7/3 (molar ratio)). 1 mL of the obtained stock solution was added to 1 L of ion-exchanged water to adjust the German hardness to 5° dH to obtain hard water. In the following evaluations, this hard water was used unless otherwise specified.
（２）カーボン再汚染防止性の評価
ガラス規格瓶（Ｎｏ．６規格、石田容器株式会社）にサンプルの衣料用液体洗浄剤組成物を５０ｇ充填し、４０℃で２か月静置した。ガラス規格瓶内の衣料用液体洗浄剤組成物を上部からサンプリングし、ポリエステルジャージ布（６ｃｍ×６ｃｍ、谷頭商店）１枚につき衣料用液体洗浄剤組成物０．２５ｇを直接塗布した。上記硬度水１Ｌに、衣料用液体洗浄剤組成物を塗布した布４枚を入れ、カーボンブラック（平均粒径１５０ｎｍ、旭カーボン株式会社）０．１５ｇを加えて、ターゴトメーターを用いて、洗浄時間１０分、回転速度１００ｒｐｍ、水温３０℃の条件下で洗浄した。
汚染前の原布、及び洗浄前後の布の、５５０ｎｍにおける反射率を、それぞれ、測色色差計（日本電色株式会社製 ＳＥ２０００）を用いて測定し、次式によってカーボン再汚染防止率（％）を求めた。結果を表１に示した。
カーボン再汚染防止率（％）＝１００×［（洗浄後の反射率/洗浄前の反射率）］
(2) Evaluation of Carbon Recontamination Prevention 50 g of the sample liquid detergent composition for clothing was filled into a standard glass bottle (No. 6 standard, Ishida Container Co., Ltd.) and left to stand at 40°C for 2 months. The liquid detergent composition for clothing in the standard glass bottle was sampled from the top, and 0.25 g of the liquid detergent composition for clothing was directly applied to one piece of polyester jersey cloth (6 cm x 6 cm, Tanigashira Shoten). Four pieces of cloth coated with the liquid detergent composition for clothing were placed in 1 L of the above hard water, and 0.15 g of carbon black (average particle size 150 nm, Asahi Carbon Co., Ltd.) was added, and the cloth was washed using a tergotometer under the conditions of a washing time of 10 minutes, a rotation speed of 100 rpm, and a water temperature of 30°C.
The reflectance at 550 nm of the original cloth before contamination and the cloth before and after washing was measured using a colorimeter (SE2000, manufactured by Nippon Denshoku Co., Ltd.), and the carbon redeposition prevention rate (%) was calculated using the following formula. The results are shown in Table 1.
Carbon redeposition prevention rate (%) = 100 x [(reflectance after cleaning/reflectance before cleaning)]
表１から明らかなように、実施例１～１５の組成物は、分離安定性が良好で、且つカーボン再汚染防止率も高い。 As is clear from Table 1, the compositions of Examples 1 to 15 have good separation stability and high carbon redeposition prevention rates.
一方、（ａ）成分の界面活性剤の含有量が５質量％よりも少ない比較例１では、パール剤の分離がみられ（分離安定性が評価１）、またカーボン再汚染防止率も６７％と低かった。（ｂ）成分のパール剤を５質量％よりも多く含む比較例３では、カーボン再汚染防止率が５９％と低かった。更に（ｃ）成分の水溶性無機金属塩の含有量が１質量％に満たない比較例４では、パール剤の分離がみられ（分離安定性が評価１．４）、またカーボン再汚染防止率も７２％と低かった。なお、パール剤を含まない比較例２では、またカーボン再汚染防止率は９１％と高いものの、光沢はみられなかった。 On the other hand, in Comparative Example 1, where the content of the surfactant (a) was less than 5% by mass, separation of the pearling agent was observed (separation stability was rated 1), and the carbon redeposition prevention rate was also low at 67%. In Comparative Example 3, where the content of the pearling agent (b) was more than 5% by mass, the carbon redeposition prevention rate was low at 59%. Furthermore, in Comparative Example 4, where the content of the water-soluble inorganic metal salt (c) was less than 1% by mass, separation of the pearling agent was observed (separation stability was rated 1.4), and the carbon redeposition prevention rate was also low at 72%. In Comparative Example 2, which did not contain a pearling agent, the carbon redeposition prevention rate was high at 91%, but no gloss was observed.
以上の結果から、（ａ）成分の界面活性剤、（ｂ）成分のパール剤及び（ｃ）成分の水溶性無機金属塩を所定条件で含有することにより、分離安定性に優れ、かつ良好な光沢を示し、カーボン再汚染防止率の高い衣料用液体洗浄剤組成物を提供できることが示された。 The above results show that by containing the surfactant (a), the pearling agent (b), and the water-soluble inorganic metal salt (c) under specified conditions, it is possible to provide a liquid detergent composition for clothing that has excellent separation stability, good gloss, and a high carbon redeposition prevention rate.
