The invention relates to oxybenzylidene-bornanones which correspond to the general formula: ##STR1## in which Z and Z' denote hydrogen or a radical SO.sub.3 H, at least one of the two radicals Z and Z' denoting hydrogen, R.sub.1 denotes hydrogen, an alkyl radical having 2 to 18 carbon atoms, an alkenyl radical having 3 to 18 carbon atoms, a radical ##STR2## in which R denotes H or an alkyl radical, --(CH.sub.2).sub.3 SO.sub.3 H or a divalent radical --(CH.sub.2).sub.m or --CH.sub.2 --CHOH--CH.sub.2, m having the values 1 to 10, n having the values 1 to 20 and p having the values 1 to 6, and R.sub.3 and R.sub.4 representing hydrogen or an optionally branched or hydroxylic alkyl radical, or forming an amino-aliphatic heterocyclic ring with the nitrogen atom, R.sub.2 denotes a hydrogen atom, an alkoxy radical or a divalent radical --O-- bonded to the radical R.sub.1 if the latter is also divalent, and q denotes 1 or 2; if q has the value 2, R.sub.1 is a divalent radical, and, if R.sub.1 denotes hydrogen, R.sub.2 also denotes hydrogen. These compounds can be used in cosmetic compositions for providing protection against actinic rays.
本发明涉及与一般公式相对应的氧苯甲酰基-
丙烷酮:##STR1## 其中Z和Z'表示氢或SO.sub.3 H基团,其中至少一个基团Z和Z'表示氢,R.sub.1表示氢、具有2至18个碳原子的烷基基团、具有3至18个碳原子的烯基基团、##STR2## 其中R表示H或烷基基团,--(CH.sub.2).sub.3 SO.sub.3 H或二价基团--(CH.sub.2).sub.m或--CH.sub.2 --CHOH--CH.sub.2,其中m的值为1至10,n的值为1至20,p的值为1至6,R.sub.3和R.sub.4表示氢或可选择支链或具有羟基的烷基基团,或与氮原子形成
氨基-脂肪环状环,R.sub.2表示氢原子、烷氧基或二价基团--O--,如果前者也是二价基团,则与基团R.sub.1结合,q表示1或2;如果q的值为2,R.sub.1是二价基团,如果R.sub.1表示氢,则R.sub.2也表示氢。这些化合物可用于化妆品组合物中,用于提供对光
化学射线的保护。
