Anti-sunburn compositions are provided which comprise, as active ingredient, at least one compound of the general formula: ##STR1## in which: R.sub.1 is selected from hydrogen, alkyl radicals containing 1 to about 12 carbon atoms and optionally branched carboxyalkyl radicals containing 1 to 4 carbon atoms; R.sub.2 is selected from hydrogen, alkoxy radicals containing 1 to 4 carbon atoms, at least one alkyl and carboxyalkyl radical containing 1 to 4 carbon atoms, and halogen atoms. R.sub.3 is selected from hydrogen, carboxyalkyl radicals containing 1 to 4 carbon atoms and --S--R.sub.8 radicals, each of R.sub.4, R.sub.5, R.sub.6 and R.sub.7 is independently selected from hydrogen, and alkyl, carboxyalkyl and alkoxy radicals containing 1 to 4 carbon atoms, provided that if R.sub.3 denotes hydrogen, at least one of the radicals R.sub.1 R.sub.2, R.sub.4, R.sub.5, R.sub.6 and R.sub.7 is not hydrogen, in an amount of at least about 0.05% by weight based on the total weight of the composition. These compounds have good solubility properties enabling a large number of different types of formulation to be prepared, these formulations being adjusted to meet the requirements of the skin to be protected.
提供了一种抗晒伤组合物,其活性成分至少包含一种通式为:##STR1##的化合物,其中:R1选自氢、含有1至约12个碳原子的直链或支链烷基以及含有1至4个碳原子的羧烷基;R2选自氢、含有1至4个碳原子的烷氧基、至少一个含有1至4个碳原子的烷基和羧烷基以及卤素原子;R3选自氢、含有1至4个碳原子的羧烷基以及--S--R8基团;R4、R5、R6和R7各自独立地选自氢、含有1至4个碳原子的烷基、羧烷基和烷氧基,条件是如果R3表示氢,则至少有一个R1、R2、R4、R5、R6和R7基团不是氢,其含量基于组合物的总重量至少约为0.05%。这些化合物具有良好的溶解性,能够制备多种不同类型的配方,这些配方可以根据需要保护的皮肤的要求进行调整。
