  • COMPOSITIONS COMPRISING DERMATAN SULFATE AND CHONDROITIN SULFATE AND USE THEREOF IN COSMETOLOGICAL COMPOSITIONS
    Publication number: 20220023185
    Abstract: The present invention is directed to a composition comprising from 0.1 to 10.0 wt % of a mixture of glycosaminoglycans comprising dermatan sulfate and chondroitin sulfate, wherein the amount of dermatan sulfate is at least 5% and not more than 95% by weight, and the amount of chondroitin sulfate is at least 5% and not more than 95% by weight, based on the total amount of glycosaminoglycans. Furthermore, the invention is also directed to the use of a glycosaminoglycans composition comprising dermatan sulfate and chondroitin sulfate, wherein the amount of dermatan sulfate is at least 5% and not more than 95% by weight, and the amount of chondroitin sulfate is at least 5% and not more than 95% by weight, based on the total amount of glycosaminoglycans, as an anti-age composition.

  • Multistep process for the physical depolymerization of heparin and products obtained therefrom
    Patent number: 7939512
    Abstract: The present invention is directed to a multistep process for the physical depolymerization of heparin wherein heparin is subjected to at least two ?-ray irradiations and wherein between two irradiation steps the depolymerised heparin is subjected to a separation step and only a fraction of the depolymerised heparin obtained from the first irradiation is subjected to the second irradiation step. It is also directed to heparin-derived oligosaccharide fractions obtainable by the process of the invention.

  • Process for the physical depolymerization of glycosaminoglycanes and products obtained therefrom
    Patent number: 7605242
    Abstract: The invention relates to a process for the depolymerization of glycosaminoglycanes characterized by the use of UVC radiation. The invention also relates to the intermediate depolymerized heparin obtained by the process. The intermediate depolymerized heparin can be dissolved in a buffer solution and fractionated by gel permeation for obtaining the desired molecular weight.
