摘要:
A process for the production of a solubilized protein is disclosed, which is obtained by reducing disulfide bonds in a disulfide bond-containing water-insoluble protein material into mercapto groups and subsequently converting a part or an entire portion thereof into carboxymethyldisulfide groups. In particular, the disclosed process for the production of a solubilized protein which comprises (a) treating a disulfide bond-containing water-insoluble protein material with an aqueous alkaline solution of a reducing agent, and (b) reacting the protein treated by step (a) with thioglycolic acid in the presence of an oxidizing agent under a weakly acidic to a weakly alkaline condition. A process for the production of regenerated protein products, which comprises regenerating disulfide bonds in the solubilized protein, is also disclosed.
摘要:
The present invention provides a hair cosmetic composition containing an antibody (a) to hair or a hair extract obtained from egg yolk of poultry immunized with the hair or hair extract, and a polymer emulsion (b). The hair cosmetic composition of the invention can provide excellent properties including softness, moistened feel, and smoothness. In addition, since it is adsorbed only onto a specified part of the hair, stickiness or greasiness of the hair can be prevented. The composition also prevents occurrence of split hairs, and even repair the split hairs. These effects are not lost by repeated ordinary shampooings.

摘要:
A hair care product contains a yolk antibody (a yolk-derived, anti-hair antibody) which has been obtained from an egg of a domestic fowl immunized using, as an antigen, whole human hair, e.g., normal human hair or human hair damaged by permanent waving, dyeing or bleaching, hair particles obtained by grinding constituent tissues of human hair, the keratin protein extracted from the human hair, or a hydrolysate of the keratin protein.
