| abstract |
A cosmetic or pharmaceutical composition is provided comprising: a) 0.001 to less than 0.2 % by weight, based on the weight of the total composition, of a scleroglucan having a mean molecular weight of 1x10<6> to 12x10<6>; b) a cosmetically or pharmaceutically acceptable carrier; and, optionally, c) lactic acid, a lactate and/or pentanediol. The composition shows advantageous effects, such as moisturization of skin or mucosa, and has an antiaging and revitalizing effect on the skin. When combined with a certain bactericide as explained in claim 1 , compositions containing native polysaccharides of the glucan class in general, especially of the scleroglucan as of component a), are well suitable to reduce the number of bacteria in mucosal or oral environments and minimise adhesion, while retaining a pleasant feeling on the mucosa or gingiva. Plaque thus can be efficiently prevented or removed. |
