摘要:
This present invention provides a process for keratin hydrolysis by means of microbiological and/or enzymatic processes. In particular, the keratin is derived from feathers of animals, such as chicken and are submmited to hydrolysis by a strain of Bacillus sp. The hydrolysates have molecular weight lower than 500 Da, which makes them ideal for cosmetic applications, particularly for applications in compositions for treatment of hair fiber re-building.
