Description

皮膚洗淨劑組成物 Skin detergent composition

本發明係關於一種皮膚洗淨劑組成物。 This invention relates to a skin cleanser composition.

近年來，對身體洗淨劑要求對皮膚之溫和性。尤其是關於洗淨時之泡沫，亦有消費者認為若利用無彈性之質地較粗之泡沫持續有摩擦的洗淨，則會引起皮膚之乾燥、或斑點、皺紋等皮膚問題，隨著抗衰老意識之提高，要求可獲得更有彈性之泡沫之洗淨劑。 In recent years, body cleansers have been required to be mild to the skin. Especially with regard to the foam during washing, there are also consumers who believe that if the foam with a thicker inelastic texture is continuously rubbed, it will cause dry skin, or spots, wrinkles and other skin problems, along with anti-aging. Increased awareness requires a more flexible foaming detergent.

可列舉使脂肪酸晶析而成之糊狀之洗淨劑作為一般認為可獲得有彈性的泡沫之洗淨劑之一。於專利文獻1中，揭示有脂肪酸與陽離子性高分子之組合。 A paste-like detergent obtained by crystallizing a fatty acid is one of the detergents which are generally considered to be capable of obtaining an elastic foam. Patent Document 1 discloses a combination of a fatty acid and a cationic polymer.

又，為了使泡沫產生彈性，業者嘗試將陰離子界面活性劑與特定之非離子界面活性劑組合而強化泡沫膜之方法(專利文獻2)、及藉由將特定之脂肪酸鹽與其他界面活性劑組合，而形成均質且濃稠之泡沫質地(專利文獻3)。 Further, in order to impart elasticity to the foam, the inventors attempted to combine the anionic surfactant with a specific nonionic surfactant to strengthen the foam film (Patent Document 2), and by combining a specific fatty acid salt with other surfactants. Thereby, a homogeneous and thick foam texture is formed (Patent Document 3).
