Description
本発明は、クリーム状の洗浄剤組成物に関し、更に詳しくは、使用性、泡立ち、泡質に優れ、洗浄時の感触および洗浄後の肌の感触が良好であり、保存安定性にも優れる低刺激性のクリーム状洗浄剤組成物に関する。 The present invention relates to a creamy detergent composition, and more specifically, it is excellent in usability, foaming, foam quality, feel during washing and skin feel after washing, and excellent in storage stability. The present invention relates to an irritating creamy detergent composition.
従来、洗顔料などのクリーム状の皮膚洗浄剤としては、高級脂肪酸アルカリ塩（石鹸）を主洗浄成分に用いたものが広く使用されている。このような石鹸を用いた洗浄剤組成物は、泡立ちやさっぱり感では優れるものの、すすぎ時に肌にきしみ感を感じる、洗浄後につっぱり感を感じる、硬水中では泡立ちや洗浄力が著しく低下するといった問題点がある。また、保存安定性においても、低温域で石鹸が結晶化したり、高温域で離水するといった問題点もある。 Conventionally, as a creamy skin cleanser such as a facial cleanser, those using higher fatty acid alkali salts (soaps) as a main cleaning component have been widely used. Such a detergent composition using soap is superior in foaming and refreshing feeling, but feels squeezed on the skin when rinsing, feels refreshing after washing, and foaming and detergency is significantly reduced in hard water. There is a point. In addition, the storage stability also has problems such as soap crystallization at low temperatures and water separation at high temperatures.
このような問題点を解決する手段として、特許文献１には、石鹸とアシルメチルタウリン塩型陰イオン性界面活性剤、非イオン性界面活性剤を組み合わせたクリーム状洗浄剤組成物が開示されているが、この組成物においては、すすぎ時の肌のきしみ感や洗浄後のつっぱり感を低減する効果が十分に満足のいくものではなかった。 As means for solving such problems, Patent Document 1 discloses a creamy detergent composition comprising a combination of soap, an acylmethyl taurine salt type anionic surfactant, and a nonionic surfactant. However, in this composition, the effect of reducing the squeaky feeling of the skin at the time of rinsing and the feeling of tension after washing was not fully satisfactory.
更に、石鹸を用いたクリーム状洗浄剤組成物の問題点を解決する手段として、石鹸以外の陰イオン性界面活性剤を主洗浄成分として用いたものが提案されている。特許文献２には、Ｎ−アシル酸性アミノ酸塩と多価アルコールと非イオン性界面活性剤を組み合わせたクリーム状洗浄剤組成物が、特許文献３には、Ｎ−アシル中性アミノ酸塩を用いたクリーム状洗浄剤組成物がそれぞれ開示されているが、これらの組成物においては、泡立ちや泡質、保存安定性が十分に満足のいくものでなかった。また、特許文献４には、架橋型ポリアクリル酸とグリセリンと陰イオン性界面活性剤を組み合わせた洗浄剤組成物が、特許文献５には、ポリオキシアルキレンアルキルグルコシドと陰イオン性界面活性剤を組み合わせた洗浄剤組成物がそれぞれ開示されているが、これらの組成物においては、洗浄時の感触や洗浄後の肌の感触が十分に満足のいくものではなかった。 Further, as means for solving the problems of the creamy detergent composition using soap, those using an anionic surfactant other than soap as a main cleaning component have been proposed. Patent Document 2 uses a creamy detergent composition in which an N-acyl acidic amino acid salt, a polyhydric alcohol, and a nonionic surfactant are combined, and Patent Document 3 uses an N-acyl neutral amino acid salt. Although creamy detergent compositions have been disclosed, these foams were not sufficiently satisfactory in foaming, foam quality and storage stability. Patent Document 4 discloses a cleaning composition comprising a combination of cross-linked polyacrylic acid, glycerin and an anionic surfactant. Patent Document 5 discloses a polyoxyalkylene alkyl glucoside and an anionic surfactant. The combined detergent compositions are disclosed, but in these compositions, the feeling at the time of washing and the feeling of the skin after washing were not sufficiently satisfactory.
本発明の目的は、使用性、泡立ち、泡質に優れ、洗浄時の感触および洗浄後の肌の感触が良好であり、保存安定性にも優れる低刺激性のクリーム状洗浄剤組成物を提供することにある。 The object of the present invention is to provide a low-irritant creamy detergent composition that is excellent in usability, foaming and foam quality, has a good feeling during washing and a feeling of the skin after washing, and has excellent storage stability. There is to do.

That is, the detergent composition of the present invention comprises (a) 10-40% by mass of an acylmethyl taurine salt type anionic surfactant represented by the following formula (I), (b) 50-89% by mass of glycerin, ( c) A creamy detergent composition comprising 0.5 to 10% by mass of a fatty acid having 8 to 20 carbon atoms and (d) 0 to 20% by mass of water.
（式中のＲ1ＣＯは炭素数８〜２０のアシル基を示し、Ｍ1はアルカリ金属原子、１／２アルカリ土類金属原子、アンモニウム、有機アンモニウムまたは塩基性アミノ酸陽イオン基を示す。） (In the formula, R 1 CO represents an acyl group having 8 to 20 carbon atoms, and M 1 represents an alkali metal atom, 1/2 alkaline earth metal atom, ammonium, organic ammonium, or a basic amino acid cation group.)
この洗浄剤組成物において、アシルメチルタウリン塩型陰イオン性界面活性剤は粉体化物であっても良い。また、この洗浄剤組成物は、（ｅ）クエン酸ナトリウム０．１〜５質量％をさらに含有していても良い。 In this detergent composition, the acylmethyl taurine salt type anionic surfactant may be a powdered product. Moreover, this detergent composition may further contain (e) 0.1 to 5% by mass of sodium citrate.
本発明のクリーム状洗浄剤組成物は、低刺激性で、使用性、泡立ち、泡質に優れ、洗浄時の感触および洗浄後の肌の感触が良好であり、保存安定性にも優れる。 The creamy detergent composition of the present invention is hypoallergenic, excellent in usability, foaming and foam quality, has a good feeling during washing and a feeling of the skin after washing, and is excellent in storage stability.

実施例１〜５の評価結果より、本発明のクリーム状洗浄剤組成物は、チューブ容器から出し易い、すなわち使用性が良好で、泡立ち、泡質に優れ、洗浄時の感触および洗浄後の肌の感触が良好であり、保存安定性にも優れていた。 From the evaluation results of Examples 1 to 5, the creamy detergent composition of the present invention is easy to take out from the tube container, that is, has good usability, foaming, excellent foam quality, feel during washing, and skin after washing. The touch was good and the storage stability was also excellent.
一方、比較例１〜６のクリーム状洗浄剤組成物では、十分な性能が得られなかった。具体的には、比較例１では、（ａ）成分の含有量が本発明の範囲より少ないため、使用性、泡立ち、泡質、保存安定性が悪く、洗浄時の感触、洗浄後の肌の感触も十分ではなかった。比較例２では、（ａ）成分の含有量が本発明の範囲より多く、（ｂ）成分の含有量が本発明の範囲より少ないため、使用性、洗浄後の肌の感触が悪く、泡立ち、洗浄時の感触、保存安定性も十分ではなかった。比較例３では、本発明で規定する（ｂ）成分の代わりに１，３−ブチレングリコールを用いているため、使用性、泡立ち、泡質、洗浄時の感触、洗浄後の肌の感触が悪く、保存安定性も十分ではなかった。比較例４では、（ｃ）成分が含まれていないため、泡質が悪く、洗浄時の感触も十分ではなかった。比較例５では、（ｃ）成分の含有量が本発明の範囲より多いため、使用性、泡立ちが悪く、泡質、洗浄時の感触、洗浄後の肌の感触、保存安定性も十分ではなかった。比較例６では、（ｂ）成分の含有量が本発明の範囲より少なく、（ｄ）成分の含有量が本発明の範囲より多いため、使用性、保存安定性が悪く、洗浄後の肌の感触も十分ではなかった。 On the other hand, sufficient performance was not obtained with the creamy detergent compositions of Comparative Examples 1-6. Specifically, in Comparative Example 1, since the content of the component (a) is less than the range of the present invention, usability, foaming, foam quality, storage stability is poor, feel at the time of washing, skin after washing The touch was not enough. In Comparative Example 2, since the content of the component (a) is more than the range of the present invention and the content of the component (b) is less than the range of the present invention, the usability, the feeling of the skin after washing is bad, foaming, The feel during washing and storage stability were not sufficient. In Comparative Example 3, since 1,3-butylene glycol is used instead of the component (b) defined in the present invention, usability, foaming, foam quality, feel during washing, and skin feel after washing are poor. The storage stability was not sufficient. In Comparative Example 4, since the component (c) was not included, the foam quality was poor and the feel during washing was not sufficient. In Comparative Example 5, since the content of the component (c) is larger than the range of the present invention, usability and foaming are poor, foam quality, feel during washing, skin feel after washing, and storage stability are not sufficient. It was. In Comparative Example 6, since the content of the component (b) is less than the range of the present invention and the content of the component (d) is greater than the range of the present invention, the usability and storage stability are poor, and the skin after washing The touch was not enough.
本発明のクリーム状洗浄剤組成物は、低刺激性で、使用性、泡立ち、泡質に優れ、洗浄時の感触および洗浄後の肌の感触が良好であり、保存安定性にも優れるから、皮膚用の洗浄剤、特にクレンジング料や洗顔料として好適に使用し得る。 The creamy detergent composition of the present invention is hypoallergenic, excellent in usability, foaming, foam quality, feel during washing and skin feel after washing, and excellent in storage stability. It can be suitably used as a skin cleanser, in particular as a cleansing agent or facial cleanser.
