ABSTRACT:
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) ##STR1## in which each R.sub.1 and each R.sub.2 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 1 is a value of 0 to 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.
