Abstract:
A method of treating skin for prophylaxis and/or therapy of diseases and/or irritations induced by oxidative stress in the skin, comprising topically applying a composition to the skin, said composition containing as an active ingredient a therapeutically effective amount of at least one glucan ether derivative, said at least one glucan ether derivative comprising respective monomer units of a formula I and a formula II: wherein the monomer units of the formula I are connected with the monomer units of the formula II by a 1,3-beta-glycosidic bond; and in the monomer units of formula II, X is selected from the group consisting of â€”CH2â€”COOâ€”Y, â€”CH2â€”CH2â€”COOâ€”Y, CH(CH3)â€”COOâ€”Y, â€”CH2â€”CH2â€”SO3â€”Y, and mixtures thereof, and Y is selected from the group consisting of hydrogen, an alkali-metal, an alkaline-earth metal and mixtures thereof; and wherein said at least one glucan ether derivative comprises a combination of monomer units of formula I and formula II so that there is an average degree of substitution of 0.75Â±0.1.
