US Patent:

42145961, Jul 29, 1980

Filed:

Jul 31, 1978

Appl. No.:

5/929326

Inventors:

Julius F. Kaplan - Highland Park IL
Norman L. Edelberg - Vernon Hills IL
Chester A. Davis - Berwyn IL

Assignee:

Helene Curtis Industries, Inc. - Chicago IL

International Classification:

A45D 700

US Classification:

132 7

Abstract:

This invention relates to an improvement in the method of treating hair in which water wet hair is wrapped around rollers, a mercaptan-containing solution is applied to the hair on the rollers, and the mercaptan-wetted hair is thereafter neutralized with an oxidizing agent. This improvement comprises wetting the hair prior to wrapping it with an aqueous solution of a prewrap agent selected from the group consisting of alkali metal and ammonium sulfites and alkali metal and ammonium bisulfites. These prewrap agents are present at about 0. 1 to about 1. 0 Molar, at a pH of about 6. 5 to about 7. 5 and cleave no more than about 5 percent of the hair disulfide bonds before the mercaptan-containing solution is applied.

US Classification:

132 7

Abstract:

An improved hair treating composition for waving and straightening hair is provided. The novel composition comprises from about 0. 5 to about 15 percent by weight of a reducing agent selected from the group consisting of ammonium and sodium sulfites and bisulfites and from about 0. 1 to about 5. 0 percent by weight of a quaternary ammonium salt of a mink oil fatty acid and has a pH between 6. 5 and 6. 9.
