ABSTRACT:
An olefin wax (A) is (i) a copolymer (A1) obtained by copolymerizing ethylene and at least one diene or a copolymer (A2) obtained by copolymerizing ethylene, at least one olefin selected from α-olefins of 3 to 12 carbon atoms and at least one diene; wherein (ii) the content of unsaturated groups per one molecule is in the range of 0.5 to 3.0 groups; (iii) the density is in the range of 870 to 980 kg/m3; (iv) the melting point is in the range of 70 to 130° C.; (v) the number-average molecular weight is in the range of 400 to 5,000; and (vi) the ratio (Mw/Mn) of the weight-average molecular weight to the number-average molecular weight is not more than 4.0. A silicone-modified olefin wax can be obtained by reacting hydrogen silicone with the olefin wax (A). Cosmetics contain the silicone-modified olefin wax.
