Treatment of ashy skin by a topical composition and methods of manufacture thereof

摘要

A topical preparation for treating ashy skin and a method of manufacture thereof. The topical preparation is a single phase, hydrophobic, lipophilic preparation comprising plant-based butters that have a melting point around the temperature of the skin surface. The melting point of the mixture is stabilized by a tempering process, minimizing polymorphism. The topical preparation is applied to skin having an ashy appearance and is absorbed into the top layers without leaving a white residue. The topical preparation is translucent, non-irritating and has natural sunscreen properties.

主权项

1. A method of preparing a topical preparation for treating ashy skin, comprising:
selecting a plurality of plant-derived butters having a melting point around 37 degrees Centigrade, said plant-derived butters selected from the group consisting of mango butter, shea butter, cocoa butter, aloe butter and avocado butter; melting at least one of said plant-derived butters with a heat source at around 58 degrees Centigrade to form a butter base in a molten state; cooling the molten butter base by mixing at least one additional plant-derived butter and a liquid fatty acid into the molten butter base at low sheer to form an anhydrous slurry; slowly cooling the anhydrous slurry in a controlled manner so as to control crystallization and polymorphism, resulting in polymorphs of said anhydrous slurry having a melting point around 37 degrees Centigrade; cooling the anhydrous slurry into a semi-solid state; and mixing a polysiloxane into said cooled slurry at low shear until the mixture is completely blended to form said topical preparation.
