Abstract
This invention provides an antiperspirant-deodorant cosmetic stick product consisting of a solid organic matrix which contains a homogenous dispersion of particulate antiperspirant and deodorant ingredients. A deodorant cosmetic stick product is also provided which does not contain an antiperspirant ingredient. The solid organic matrix and dispersed particle phases have densities which are sufficiently matched to prevent setting of the dispersed particles during manufacture, and to provide a cosmetic stick product with dimensional stability.
Claims3
A deodorant cosmetic stick product consisting of a solid organic matrix comprising the following parts by weight of ingredients:
- ______________________________________ volatile silicone oil 10-55 liquid emollient 1-35 low melting point wax 12-30 ______________________________________
- and the solid organic matrix has homogeneously dispersed therein between about 1-40 parts by weight water-soluble inorganic salt deodorant ingredient;
- wherein the dispersed particles have a density which is less than about one gram per cubic centimeter higher than the density of the solid organic matrix, and an average particle size between about 5-200 microns, and wherein the surfaces of the deodorant particles are coated with a hydrophilic polymer coating having a thickness in the range between about 0.1-20 microns.
