This invention relates to skin pore tighteners each of which comprises, as an active ingredient, a compound represented by the following formula:R1-OG wherein R1 represents an alkyl or alkenyl group having 8 to 32 carbon atoms, and OG represents a residual group obtained by removing a hydrogen atom from a hydroxyl group of a polyhydric alcohol, monosaccharide or oligosaccharide at least one hydroxyl group of which has been sulfated or phosphatized, or a salt thereof, and also to skin elasticity improvers each of which comprises, as an active ingredient, a glyceryl ether derivative represented by the following formula:
wherein R1 represents the same group as defined above, and X1 and X2 each independently represents a hydrogen atom, -SO3OH or -PO(OH)2 with the proviso that X1 and X2 are not hydrogen atoms at the same time, or a salt thereof.
The skin pore tighteners according to the present invention have excellent effect in tightening skin pores and rendering them less conspicuous, while the skin elasticity improvers and skin tighteners according to the present invention have superb effect in preventing and lessening skin wrinkles and sagging. Accordingly, they are useful as ordinary cosmetic preparations, as cosmetic preparations after depilating treatment, and also as cosmetic preparations after removal of keratotic plugs.
本发明涉及皮肤毛孔紧致剂,其活性成分包括下式所代表的化合物:R1-OG 其中 R1 代表具有 8 至 32 个碳原子的烷基或烯基,OG 代表通过从多羟基醇、
单糖或
寡糖的羟基上除去一个氢原子而得到的残基,其中至少有一个羟基已被
硫酸化或
磷酸化,或其盐,本发明还涉及皮肤弹性改善剂,每种皮肤弹性改善剂作为活性成分包括下式所代表的
甘油醚衍
生物:
其中 R1 代表与上述定义相同的基团,X1 和 X2 各自独立地代表氢原子、-SO3OH 或-PO(OH)2,但 X1 和 X2 不能同时为氢原子,或其盐。
根据本发明的皮肤毛孔收紧剂在收紧皮肤毛孔和使其不那么明显方面具有极好的效果,而根据本发明的皮肤弹性改善剂和皮肤收紧剂在防止和减少皮肤皱纹和松弛方面具有极好的效果。因此,它们既可作为普通的化妆品制剂,也可作为脱毛治疗后的化妆品制剂,还可作为去除角化栓后的化妆品制剂。
