Patent ID: 6989150

Claim:
Cosmetic active substance preparation with a high radical protection factor, which comprises a content of (a) a product obtained by extraction of the bark of Quebracho Blanco and subsequent enzymatic hydrolysis, containing at least 90 percent by weight of proanthocyanidine oligomers and up to percent by weight of gallic acid, where the content of (a), which is available in a concentration of 2 percent by weight linked to a microcapsule ranges from 0.1 to 10 wt. %; (b) an extract of the silkworm obtained by extraction, containing the peptide cecropine, amino acids and a vitamin mix, where the content of (b) ranges from 0.1 to 10 wt. %; (c) a non-ionic, cationic or anionic hydrogel or mixture of hydrogels, where the content of (c) ranges from 0.1 to 5 wt %; and which is prepared by solution of a gel forming agent in water at temperatures above 40–50° C. and which hydrogel takes the gel structure at temperatures between 10 and 30° C.; (d) one or several phospholipids in the range of 0.1 up to 30 wt. %; (e) an ultrasound decomposition product of a yeast containing at least 150 units of superoxide dismutase per ml, wherein the content of the decomposition product is in the range from 0.5 to 4 percent by weight; (f) one or more cyclodextrines selected from the group consisting of β- and γ-cyclodextrins with a share of 0.5 to 8% by weight; and (g) up to 100 percent by weight of water; related to the total weight of the active substance preparation each.
