This invention relates to non-hydrolyzable, non-irritating, hair, skin and textile substantive quaternary ammonium salts of a para-dialkylamino benzamide having the formula ##STR1## wherein R' and R" are each selected from the group of C.sub.1 to C.sub.2 alkyl; n is an integer having a value of from 2 to 6; R is an alkyl radical having from 1 to 30 carbon atoms; R.sub.1 and R.sub.2 are each selected from the group of C.sub.1 to C.sub.4 alkyl, hydrogen and, alternatively, R.sub.1 and R.sub.2, together with the attached cationic nitrogen atom can form a 5 to 6-membered heterocyclic ring selected from the group of ##STR2## and X is an anion. These benzamide derivatives are active sunscreening agents which are usefully employed at a concentration of from about 0.5 to about 10 wt. % in a formulation requiring protection against the harmful effects of sunlight, such as skin burn, hair damage, color fading, etc.
本发明涉及一种对头孢二甲基氨基苯酰胺的非水解、非刺激、对头发、皮肤和纺织品有实质作用的季铵盐,其具有以下结构式:##STR1## 其中R'和R"分别选择自C.sub.1到C.sub.2烷基的一组;n是一个整数,取值范围为2到6;R是具有1到30个碳原子的烷基基团;R.sub.1和R.sub.2分别选择自C.sub.1到C.sub.4烷基、氢和/或R.sub.1和R.sub.2与附加的阳离子氮原子一起可以形成选择自##STR2## 的5到6元杂环环;X是一个阴离子。这些苯甲酰胺衍生物是活性防晒剂,可在需要保护免受阳光有害影响的配方中浓度为约0.5至约10重量%使用,例如皮肤灼伤、头发损伤、色彩褪色等。
