Abstract
Abstract The invention relates to a composition for topical administration. This composition contains an active proportion, namely from 0.5 to 25% by weight and preferably from 2 to 10% by weight, of a hydrolysate of lactalbumin obtained solely by the action of an endopeptidase, said hydrolysate consisting essentially of peptides having a molecular weight of from 200 to 5000. This composition may be used as a cosmetic or therapeutic agent.

Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
73 words
In a composition for topical administration containing a carrier and an active ingredient, the improvement which comprises the active ingredient being a hydrolysate of lactalbumin obtained solely by the action of an endopeptidase, said hydrolysate consisting essentially of peptides having a molecular weight of from 200 to 5,000 and being present in the composition in a proportion of from 0.5 to 25% by weight, expressed as dry weight of hydrolysate in the composition.
Claim 2
Dependent Claim
73 words
In a composition for topical administration containing a carrier and an active ingredient, the improvement which comprises the active ingredient being a hydrolysate of lactalbumin obtained solely by the action of an endopeptidase, said hydrolysate consisting essentially of peptides having a molecular weight of from 200 to 5,000 and being present in the composition in a proportion of from 0.5 to 25% by weight, expressed as dry weight of hydrolysate in the composition.
Claim 3
Dependent Claim
33 words
A composition as claimed in claim 1, characterised in that it contains the hydrolysate in a proportion of from 2 to 10% by weight, expressed as dry weight of hydrolysate in the composition.
Claim 4
Dependent Claim
24 words
A composition as claimed in claim 1, characterised in that the hydrolysate is obtained by hydrolysis of lactalbumin with enzymatically pure trypsin or chymotrypsin.
