Abstract

Abstract Translated from French Selon ce procédé, on met en présence du collagène éventuellement déréticulé, sous forme de suspension homogène ou de solution, avec une solution de glycosaminoglycane et l'on porte le pH du mélange à 7. According to this process, the collagen, optionally de-crosslinked, is placed in the form of a homogeneous suspension or solution, with a glycosaminoglycan solution and the pH of the mixture is brought to 7. Les compositions ainsi obtenues peuvent être appliquées dans les domaines cosmétiques, pharmaceutiques, vétérinaires et thérapeutiques, tels que par exemple en paradontologie, en chirurgie osseuse et en tant que pansements hémostatiques et cicatriciels, ainsi que dans les domaines analytiques et notamment comme supports de molécules actives telles que des enzymes. The compositions thus obtained can be applied in the cosmetic, pharmaceutical, veterinary and therapeutic fields, such as for example in paradontology, in bone surgery and as hemostatic and scar dressings, as well as in the analytical fields and in particular as carriers of active molecules. such as enzymes.
