Abstract

Hydrogen peroxide-based compositions for the manufacture of, or use as fixers for, permanent-waving/straightening. The compositions comprise hydrogen peroxide and at least one carboxylic acid and/or a salt thereof, for example, citric acid, as well as at least one alkalinizing amino compound, for example, aqueous ammonia. Processes for the permanent-reshaping and/or shape-stabilizing of keratinous materials, especially hair, are also disclosed. The compositions according to the invention make it possible to overcome the drawbacks relating to softness, sensitization to dyeing, etc., associated in the prior art particularly with repeated application to the hair of permanent-waving/straightening operations, in particular those involving the use of carbonate.

Claims

1. A method for improving a property of the hair during the fixative stage of a permanent waving/straightening of said hair;

wherein said property is selected from the group consisting of softness, crumpling and smoothing said method comprising and oxidizing wherein said oxidizing comprises applying to said keratinous material a hydrogen peroxide-based composition comprising hydrogen peroxide and (i) at least one cosmetically acceptable carboxylic acid and/or a salt thereof, and (ii) at least one cosmetically acceptable alkalinizing amino compound,

wherein the pH of said composition ranges from 2.8 to 6.0.

2. A multi-compartment kit which comprises in a first compartment, a reducing composition, and in a second compartment, a hydrogen peroxide-based composition comprising hydrogen peroxide and (i) at least one cosmetically acceptable carboxylic acid and/or a salt thereof, and (ii) at least one cosmetically acceptable alkalinizing amino compound,

wherein said carboxylic acid is a lactic, tartaric, acetic, glycolic or citric acid, said alkalinizing amino compound is monoethanolamine, triethanolamine, isopropanolamine or 1,3-propanediamine, and

wherein the pH of said composition ranges from 2.8 to 6.0.

3. A kit according to claim 2, wherein said reducing composition is a carbonate-containing reducing composition capable of and designed for carrying out the first step of a permanent-waving/straightening operation and wherein said hydrogen peroxide-based composition is capable of and designed for carrying out a subsequent step of said permanent-waving/straightening operation.

4. A process for improving a property of the hair during the fixative stage of a permanent reshaping and/or shape-stabilizing of said hair;

wherein said property is selected from the group consisting of softness, crumpling and smoothing, which comprises in a first step, reducing the disulphide bonds of keratin by application to said keratinous material of a reducing composition, and in a subsequent step, re-forming said disulphide bonds by application to said keratinous material of a hydrogen peroxide-based oxidizing composition comprising hydrogen peroxide and (i) at least one cosmetically acceptable carboxylic acid and/or a salt thereof, and (ii) at least one cosmetically acceptable alkalinizing amino compound,

wherein the pH of said composition ranges from 2.8 to 6.0.

5. A process according to claim 4, wherein said reducing composition is a carbonate-containing reducing composition.

6. A process according to claim 4, which comprises the following steps:

(i) applying said reducing composition to the keratinous material to be treated, and placing the keratinous material under mechanical tension before, during or after applying said reducing composition;

(ii) rinsing the treated keratinous material;

(iii) applying the oxidizing composition or fixer to the rinsed keratinous material;

(iv) separating the treated keratinous material from the tension means used in step (i); and

(v) rinsing the separated keratinous material.

7. A method for the manufacture of a fixer for permanent-waving/straightening which comprises combining hydrogen peroxide and (i) at least one carboxylic acid and/or a salt thereof, and (ii) at least one alkalinizing amino compound to obtain a hydrogen peroxide-based fixer,

wherein said carboxylic acid is a lactic, tartaric, acetic, glycolic or citric acid, said alkalinizing amino compound is monoethanolamine, triethanolamine, isopropanolamine or 1,3-propanediamine, and

wherein the pH of said composition ranges from 2.8 or 6.0.

8. A hydrogen peroxide-based composition comprising hydrogen peroxide and (i) at least one cosmetically acceptable carboxylic acid and/or a salt thereof, and (ii) at least one cosmetically acceptable alkalinizing amino compound,

wherein said carboxylic acid is a lactic, tartaric, acetic, glycolic or citric acid, said alkalinizing amino compound monoethanolamine, triethanolamine, isopropanolamine or 1,3-propanediamine, and

wherein the pH of said composition ranges from 2.8 to 6.0.
