摘要

Lipophilized peptides are obtained by grafting lipids produced by a reaction between hydrolyzed proteins of lupin and dodecenyl succinic anhydride/octenyl succinic anhydride grafting agents, are new. Lipophilized peptides are obtained by grafting lipids produced by a reaction between hydrolyzed proteins of lupin and dodecenyl succinic anhydride/octenyl succinic anhydride grafting agents. The process further comprises: (a) solubilizing the lupin powder (200g/l) in water; (b) hydrolyzing enzymatically; (c) thermally inactivating the enzymatic activities; (d) separating the phases; (e) grafting the lipids to form lipopeptides; (f) concentrating the soluble and active molecules; and (g) sterilizing the membranes. Independent claims are also included for: (1) an active ingredient; and (2) a cosmetic composition obtained using the above process.
