Title (EN) KERATIN HYDROLYSATE FOR ORAL COSMETIC USE
(FR) HYDROLYSAT DE KÉRATINE POUR UTILISATION COSMÉTIQUE PAR VOIE ORALE
Abstract:
(EN) The present invention relates to a keratin hydrolysate comprising at least 88% by weight of free amino acids relative to the total weight of the amino acids of the hydrolysate, the remainder of the hydrolysate consisting of peptides having a molecular weight of less than or equal to 800 Daltons, said hydrolysate also comprising L-cystine in a content ranging from 4% to 6%, cysteine in a content of less than or equal to 0.1%, and tyrosine in a content of less than or equal to 0.6% by weight, relative to the total weight of the hydrolysate. It is also directed towards a process for preparing the hydrolysate, the oral cosmetic use of the hydrolysate for improving the appearance of the nails and/or of the hair, and a food supplement comprising the hydrolysate and optionally vitamins, zinc and/or L-cystine.
(FR) La présente invention concerne un hydrolysat de kératine comprenant au moins 88% en poids d'acides aminés libres par rapport au poids total des acides aminés de l'hydrolysat, le reste de l'hydrolysat étant constitué de peptides présentant une masse moléculaire inférieure ou égale à 800 Dalton, ledit hydrolysat comprend aussi de la L-cystine en une teneur comprise allant de 4 à 6%; de la cystéine en une teneur inférieure ou égale à 0,1%, de la tyrosine en une teneur inférieure ou égale à 0,6% en poids par rapport au poids total de l'hydrolysat. Elle vise aussi un procédé de préparation de l'hydrolysat; l'utilisation cosmétique, par voie orale, de l'hydrolysat pour améliorer l'aspect des ongles et/ou des cheveux; un complément alimentaire comprenant l'hydrolysat et éventuellement des vitamines, du zinc et/ou de la L-cystine.
