Abstract

Detergent Compositions having a protective effect on keratinous material incorporate a proteinaceous material whose primary amino or carboxylic acid side chain groups have been modified by reaction with C₁ -C₇ acyl- or alkyl- group-containing materials respectively to give a modified protein of isoionic point (pI) less than pH 6. Granular, bar and liquid detergent formulations embodying the invention are disclosed.

Claims

1. A composition for protecting keratinous material from the deleterious effects of detergents or from adverse climatic conditions, said composition comprising

(a) from 0.1 to 90% by weight of a foaming non cationic detergent material;

and

(b) from 0.1 to 20% by weight of a chemically modified protein having an isoionic point (pI) less than pH of 6, said chemically modified protein being selected from the group consisting of oxybutylated hydrolyzed protein and acetylated hydrolyzed protein.

2. A composition as recited in claim 1, in which the chemically modified protein is present in an amount between 2 and 6% by weight.

3. A composition as recited in claim 2, in which the chemically modified protein has a molecular weight in the range from 2000 to 5000.

4. A composition as recited in claim 3, in which the chemically modified protein is oxybutylated base hydrolyzed soy protein isolate.

5. A composition as recited in claim 3, in which the chemically modified protein is acetylated base hydrolyzed soy protein isolate.

6. A composition as recited in claim 3, in which the chemically modified protein is acetylated base hydrolyzed whey.

7. A composition recited in claim 3, in which the chemically modified protein is acetylated base hydrolyzed protein derived from yeast.

8. A composition as recited in claim 3, in which the chemically modified protein has a pI in the range of from pH2.5 to pH5.5.
