    • Provided are a hair cosmetic composition comprising an ether type cationic surfactant represented by the following formula (1): wherein, R1 represents a linear or branched C6-24 alkyl or alkenyl group, R2 and R4 each represents a C1-6 alkyl group or —(AO)nH (A: a C2-4 alkylene group, n: a number of from 1 to 6 with the proviso that n pieces of A may be the same or different and their sequence is optional), R3 represents a C1-6 alkyl group or —(A′O)mH (A′: a C2-4 alkylene group, m: a number of from 1 to 6 with the proviso that m pieces of A may be the same or different and their sequence is optional), and X− represents an anion; a hair cleansing composition containing the cationic surfactant(1); and a method of treating hair with these compositions. The hair cosmetic composition of the present invention can impart good flexibility and smoothness to hair not only when it is wetted but also after drying. When used as a hair cleansing composition, it provides excellent quality of foam and feeling upon use and exhibits good low-temperature stability.
    • 提供一种包含由下式(1)表示的醚型阳离子表面活性剂的毛发化妆品组合物:其中,R 1表示直链或支链的C 6-24烷基或链烯基,R 2和R 4各自 表示C 1-6烷基或 - (AO)n H(A:C 2-4亚烷基,n:1至6的数,条件是n个A可以相同或不同,它们的顺序为 可选),R 3表示C 1-6烷基或 - (A'O)m H(A':C 2-4亚烷基,m:1至6的数,条件是m个A 可以相同或不同,它们的顺序是任选的),而X“表示阴离子; 含有阳离子表面活性剂(1)的毛发清洁组合物; 以及使用这些组合物处理毛发的方法。本发明的毛发化妆品组合物可以赋予头发良好的柔韧性和光滑性,不仅当其被润湿时,而且在干燥之后。 当用作头发清洁组合物时,它提供优异的泡沫质量和使用感,并表现出良好的低温稳定性。
