Abstract:
1. A method of preparing a fluid cosmetic composition comprising a sebum-absorbing calcium silicate wherein said composition is in a form selected from the group consisting of a water-based formulation, a water/alcohol-based formulation, and an emulsion, wherein if said composition is in the form of an emulsion, then said sebum-absorbing calcium silicate is present within the water phase of said emulsion; wherein said cosmetic composition further comprises at least one cosmetic ingredient selected from the group consisting of: skin feel components, additional sebum absorbing materials, cosmetic preservatives, mineral fillers and extenders, color pigments, sunscreens, emollients, thickeners, opacifiers, and perfumes; and wherein said sebum-absorbing calcium silicate includes a cyclic silicone deposited thereon prior to incorporation within said composition; said method comprising the steps of: a) providing calcium silicate in particulate form; b) mixing said particulate calcium silicate with a cyclic silicone to form a premix wherein said cyclic silicone is deposited on the particles of calcium silicate; and c) combining the premix of step “b”with at least one solvent and at least one of said cosmetic ingredients to form said fluid cosmetic composition; wherein the cyclic silicone is selected from cycloheptasiloxane, cyclohexasiloxane, cyclopentasiloxane, cyclotetrasiloxane, and cyclotrisiloxane.
