ABSTRACT:
A cosmetic ingredient homogenization agent, for use in assisting and improving the homogenization of the cosmetic ingredients of a compacted powder, is a combination of the following three components: x weight percent of hollow microspheres of a thermoplastic synthetic material having a specific mass lower than 0.1 g/cm.sup.3 and having a size lower than 30 .mu.m; y weight percent of particles of hexagonal boron nitride; and z weight percent of particles of N-acyl lysine. x, y and z are numbers which vary, respectively, as follows: x: 0.2-30; y: 02.-90; and z: 8-99.78. The sum x+y+z=100. This homogenization agent can be incorporated into a cosmetic composition in the form of a compacted powder in an amount ranging from 1-55, preferably 10-35, percent by weight based on the total weight of the composition.
