Estimating the term…
The invention relates to a collagen product containing collagen of marine origin with a low odor. The collagen product includes one or more collagens or derivatives thereof, including hydrolyzates, with a low odor, at least part of the collagen or the derivatives being of marine origin and having been subjected to a deodorization treatment, particularly with an oxidizing substance such as a sulfite, hydrogen peroxide or ozone, at any stage of the manufacture of the collagen product. The invention also makes it possible to improve the mechanical properties and to use this low-odor collagen product in cosmetic or pharmaceutical products.
A collagen product comprising a collagen compound derived from marine animals, wherein said collagen compound has been subjected while present in an aqueous solution to a deodorization treatment with an oxidizing substance consisting essentially of an effective amount of ozone in said aqueous solution.
A collagen product comprising a collagen compound obtained from at least one marine animal, wherein said collagen compound has been subjected to a deodorization treatment with an oxidizing substance consisting essentially of ozone in aqueous solution at a flow rate of between about 25 and 50 l/hour/kg of collagen compound, wherein said ozone concentration is between about 20 and 50 mg/l.
A sponge, membrane or mask comprising a marine collagen compound, wherein the collagen compound has been subjected to a deodorization treatment while present in an aqueous solution with an oxidizing substance consisting essentially of an effective amount of ozone in said aqueous solution.
A cosmetic or pharmaceutical product comprising
