Patent number: 6123934Abstract: 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.Type: GrantFiled: June 20, 1997Date of Patent: September 26, 2000Assignees: Kao Corporation, Taiyo Kagaku Co., Ltd.Inventors: Takashi Koyama, Kazuyo Watanabe, Hiroshi Nojiri, Sachio Naito, Michitaka Sawada, Genji Imokawa, Hidehisa Takahashi, Toshiki Kobayashi

Patent number: 5763583Abstract: 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.
