A novel cosmetic comprises an oil gel formed by at least one metal salt of a dialkyl phosphate of the following general formula (I), (II) or (III)
in which each R1 and each R2 independently represent a saturated or unsaturated, linear or branched hydrocarbon group having from 8 to 36 carbon atoms, m is an integer of from 1 to 3, n is an integer of from 0 to 2, k is a value of 1 or 2, and I is a value of 0 or 1, and a cosmetic oil.
The metal salt of the dialkyl phosphate can yield a good oil gel when it is incorporated into the oil in an amount as small as 0.1 to 10% of the oil. Further, the dialkyl phosphate retains good feel of oils without causing oozing of the oil, crazing, discoloration, perspiration and the like.
一种新型化妆品包含一种油凝胶,它是由至少一种通式为(I)、(II)或(III)的
磷酸二烷基酯的
金属盐形成的
其中每个 R1 和每个 R2 分别代表具有 8 至 36 个碳原子的饱和或不饱和、直链或支链烃基,m 为 1 至 3 的整数,n 为 0 至 2 的整数,k 为 1 或 2 的值,I 为 0 或 1 的值,以及一种化妆品油。
当
磷酸二烷基酯的
金属盐以 0.1%至 10%的用量加入到油中时,可以产生良好的油凝胶。此外,
磷酸二烷基酯还能保持良好的油感,而不会导致油渗出、开裂、变色、出汗等现象。
