Abstract
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 Analysis
Total Claims: 9
Claim 1
Independent Claim
75 words
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.
Claim 2
Dependent Claim
75 words
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.
