Abstract
A water-based anti-microbial cosmetic preparation comprising 0.025% to 3.2% of silver-chitosan dispersion by weight and not more than 10% of a non-ionic surfactant by weight. The preparation has a ratio of non-ionic surfactant to silver chitosan by weight of at least 0.2:1 to allow the silver chitosan to form a film on the surface of the skin. The preparation has a pH of between 3 and 6.5 to ensure that the silver chitosan to ensure that the preparation is tolerable on the skin and to ensure that the silver does not precipitate. The preparation does not contain an ionic surfactant in order to avoid precipitating the silver chitosan out of the preparation.
