Disclosed herein are water-soluble UV absorbing compounds of Formula I with two quaternary ammonium centers, wherein;
R is selected from saturated or unsaturated alkyl groups with C
12
to C
22
carbon atoms and R
1
is selected from H or methoxy group. The invention further discloses the synthesis of highly substantive water-soluble UV absorbers containing two quaternary ammonium centers, cinnamidopropyl (2-hydroxypropyl alkyl dimethyl ammonium chloride) dimonium chlorides of Formula I and the compositions containing the same in personal care products.
本公开涉及具有两个季铵中心的化学式I的水溶性UV吸收化合物;其中R选自具有C12到C22碳原子的饱和或不饱和烷基基团,R1选自H或甲氧基团。该发明还公开了合成含有两个季铵中心的高度亲合水溶性UV吸收剂,即化学式I的肉桂酰丙基(2-羟基丙基烷基二甲基铵氯化物)二季铵氯化物,以及含有这种化合物的个人护理产品的组合物。
