US Classification:

424/066000, 424/068000, 241/015000

Abstract:

This invention comprises: (1) a wet grinding method for enhancing the activity of an aluminum or an aluminum/zirconium salt without the dilution and heating traditionally required wherein the enhancement is described as forming a salt wherein the amount of smaller aluminum species as represented by Peak +Peak is increased by an amount of at least 10% over the parent salt; and, if zirconium is present, the area of Peak in the parent salt is at least 10% greater than the area of Peak after grinding; (2) an enhanced aluminum or aluminum/zirconium salt itself; and (3) anhydrous (less than 4% water excluding waters of hydration for the enhanced salt) antiperspirant and/or deodorant products made with the salts described in (2).

International Classification:

A61K 8/29

US Classification:

424401000, 424063000

Abstract:

The present invention relates to particle compositions comprising a core particle that is partially coated with a first hydrophilic deposit and a hydrophobic polymeric finish, contains a small amount of water, and a compatible active present in the deposit, the finish or both. Additional alternating deposits, hydrophobic, hydrophilic or both, can be present between the first hydrophilic deposit and the hydrophobic polymeric finish. Similarly, additional compatible actives can be present in one or more of the additional alternating deposits. The invention also relates to methods of preparing the particle compositions.

Appl. No.:

Inventors:

Wilson Lee - Bloomfield NJ
Robert Bianchini - Belle Mead NJ

Assignee:

Colgate Palmolive Company - New York NY

International Classification:

A61K 732
A61K 738
A61K 700

US Classification:

424 65

Abstract:

Disclosed is a solid (e. g. , cream, such as semi-solid or soft solid) cosmetic composition containing an active cosmetic material (e. g. , a deodorant active, an antiperspirant active, a sunscreen, an insect repellent and/or an anti-fungal agent), volatile (e. g. , cyclomethicone) and linear chain (e. g. , dimethicone and/or phenyl trimethicone) silicone materials, and at least one gelling agent. The at least one gelling agent includes hexanediol-behenyl beeswax, and is included in the composition in an amount sufficient to provide the solid composition. By incorporating the hexanediol-behenyl beeswax as a gelling agent, conventional gelling agents such as fatty alcohols and hydrogenated castor oil need not be incorporated in the composition. When an antiperspirant active material is incorporated in the solid composition containing hexanediol-behenyl beeswax as a gelling agent, a solid antiperspirant composition that is efficacious and leaves no visible (white) residue, can be achieved.
