Abstract

A new type of cosmetics is prepared by incorporating therein a synthetic flaky metallic oxide having an average thickness of about 0.1 to about 2 .mu.m, an average size of about 1 to about 100 .mu.m [which is defined as an average value of (the longest diameter of flakes+shortest diameter of flakes)/2 for 100 flakes], and a refractive index of about 1.4 to about 1.8. Make-up cosmetics containing an artificially synthesized flaky metallic oxide of a low refractive index as a pigment, particularly an extender pigment have an improved touch and stability with time in use which has not been attained by conventional cosmetics.
