摘要： An oil-free and wax-free solid or powder-based cosmetic material having beneficial oil and wax characteristics without the detrimental effects thereof. The cosmetic material comprises pigments and/or pigment extenders which are surface treated with a hydrophobidizing material to become hydrophobic. The hydrophobidized cosmetic material is admixed with oil-free and wax-free binders in an aqueous slurry and then vacuum dehydrated and dried at an elevated temperature to provide the finished cosmetic product with excellent skin "feel", adhesiveness, extendibility, payoff (i.e., pickup of the product by an applicator) and uniformity characteristic of oil-containing cosmetics but without oil and its detrimental effects.
