Appl. No.:

7/986916

Inventors:

Wendy R. Greczyn - Randolph NJ
M. Stephen Lajoie - Basking Ridge NJ
John R. Berschied - Lawrenceville NJ
Lawrence Kirschner - Flanders NJ

Assignee:

Church & Dwight Co., Inc - Princeton NJ

International Classification:

A61K 732
A61K 734
A61K 738
A61K 914

US Classification:

424 65

Abstract:

This invention provides an improved process for producing an antiperspirant-deodorant cosmetic stick product. An essential aspect of the process improvement is a phased order of ingredient addition and blending of formulation ingredients under controlled temperature conditions. Another essential aspect is the incorporation of particulate antiperspirant and alkali metal bicarbonate ingredients, at least one of which has ingredient particle surfaces coated with a hydrophilic organic polymer.

Wendy R. Greczyn - Randolph NJ

Assignee:

Church & Dwight Co., Inc. - Princeton NJ

International Classification:

A61K 732

US Classification:

424 65

Abstract:

This invention provides an improved process for producing an antiperspirant-deodorant cosmetic stick product. An essential aspect of the process improvement is a phased order of ingredient addition and blending of formulation ingredients under controlled temperature conditions. A bicarbonate salt deodorant is added as the last ingredient during the processing, in order to minimize degradation of the bicarbonate salt under the elevated temperature conditions of the ingredient blending operation.

A61K 738

US Classification:

424 66

Abstract:

This invention relates to an antiperspirant stick which provides the user with excellent antiperspirant/deodorant efficacy, reduced residue and high temperature stability, which comprises: (a) from about 10 to 70 percent by weight of a volatile silicone oil; (b) from about 1. 5 to 30 percent by weight of a water-insoluble liquid emollient, characterized in that the weight ratio of volatile silicone oil to water-insoluble liquid emollient is greater than about 2. 5:1. 0; (c) from about 12 to 20 percent by weight of a low melting point wax; (d) from about 1. 0 to 15 percent by weight of a coupling agent; (e) from about 0. 50 to 3. 0 percent by weight of a surface active agent; (f) from about 18 to 30 percent by weight of an antiperspirant active material; and (g) from about 0. 05 to 30 percent by weight of a deodorant active material.
