Abstract
Description
本発明は、洗浄剤組成物に関する。 The present invention relates to a cleaning composition.
顔や全身を清浄にするための皮膚洗浄剤は、本来の目的である洗浄性に加え、豊かな起泡性、クリーミィな泡質、すすぎ性、そして使用後の肌に対してつっぱり感がなくなめらかになるなど、良好な仕上がり感が求められている。脂肪酸塩は優れた洗浄力を有することから、皮膚洗浄剤に汎用されているが、すすぎ時にきしみ感があり、使用後につっぱり感があることが知られている。従来、仕上がり感を調整するため、脂肪酸塩とともに、油分やポリマー類を配合することが検討されている(例えば、特許文献1、2)。 Skin cleanser for cleansing the face and the whole body is not only the original cleansing property but also rich foaming property, creamy foam quality, rinsing property, and no feeling of tension after use. There is a need for a good finish such as smoothness. Since fatty acid salts have excellent detergency, they are widely used in skin cleansing agents. However, it is known that there is a squeaky feeling when rinsing and a feeling of tension after use. Conventionally, in order to adjust the finished feeling, it has been studied to blend an oil or a polymer with a fatty acid salt (for example, Patent Documents 1 and 2).
従来の皮膚洗浄剤において、仕上がり感を調整するため、油分やポリマー類を配合すると、泡立ちや泡質が低下したり、洗浄時にぬるつく、ポリマーの皮膜が皮膚表面に残留することにより肌の柔らかさを損なうなどの問題があった。
本発明は、起泡性や泡質に優れ、洗浄時にぬるつきがなく、タオルドライ後にはべたつかず、しっとりした感触が得られる洗浄剤組成物に関する。
In conventional skin cleansers, if oils or polymers are added to adjust the feeling of finishing, foaming or foam quality decreases, or the skin becomes soft during washing, leaving a polymer film on the skin surface to soften the skin. There was a problem such as detracting.
The present invention relates to a detergent composition that is excellent in foaming properties and foam quality, does not feel wet during washing, does not become sticky after towel drying, and provides a moist feel.
本発明者らは、特定のポリマーと脂肪酸又はその塩を組み合わせて用いれば、上記課題を解決した洗浄剤組成物が得られることを見出した。 The present inventors have found that a cleaning composition that solves the above problems can be obtained by using a specific polymer in combination with a fatty acid or a salt thereof.
