Provided are a novel cosmetic compounding agent capable of imparting superior properties such as a water and moisture retention property to a cosmetic for use on the hair and skin; a cosmetic using the cosmetic compounding agent; and a method for producing the cosmetic. The cosmetic compounding agent of the present invention contains an organic ammonium salt having a hydrogen-bonding functional group(s) in a cation and/or an anion. In a preferable embodiment, the cation is an ammonium cations represented by the following formula (I):
N+[R1]n[R2]4-n (I)
wherein each R1 independently represents, for example, a hydroxyalkyl group in which there is at least one hydroxy group, an alkyl moiety is a linear or branched moiety having 1 to 10 carbon atoms, and the alkyl moiety may contain an oxygen atom(s), and
wherein each R2 independently represents a hydrogen atom or a linear or branched alkyl group having 1 to 18 carbon atoms, and n represents an integer of 0 to 4.
本发明提供了一种新型化妆品复配剂,该复配剂能够赋予用于头发和皮肤的化妆品以优异的性能,例如保水保湿性能;一种使用该化妆品复配剂的化妆品;以及一种生产该化妆品的方法。本发明的化妆品复配剂含有一种有机铵盐,其阳离子和/或阴离子中具有氢键官能团。在一个较好的实施方案中,阳离子是由下式(I)代表的铵阳离子:
N+[R1]n[R2]4-n (I)
其中每个 R1 独立地代表例如羟基烷基,其中至少有一个羟基,烷基是具有 1 至 10 个碳原子的直链或支链基团,烷基可含有一个或多个氧原子,以及
其中每个 R2 独立地代表氢原子或具有 1 至 18 个碳原子的直链或支链烷基,n 代表 0 至 4 的整数。
