#CMT# #/CMT# Cosmetic and pharmaceutical composition comprises sulfurated molecules having a reducing action with ascorbic acid derivatives. #CMT#USE : #/CMT# The composition is useful for clearing up human skin or reducing dark spots on the skin (claimed) due to hyperpigmentation. #CMT#ADVANTAGE : #/CMT# The composition provides pleasant odor, less irritation and clear coloring, and is stable in aqueous solution during a prolonged storage. #CMT#ORGANIC CHEMISTRY : #/CMT# Preferred Composition: The composition further comprises ortho- or para-niacinamide to increase efficiency and cosmetic action. The composition comprises 0.05-1% of an organic acid, preferably citric acid, lactic acid or glycolic acid. Preferred Components: The sulfurated molecules are L-cysteine, L-cysteineamine, dithiotreitol, methylsulfonylmethane, glutathione or alpha -lipoic acid, and have a concentration of 0.2-20%. The ascorbic acid derivatives are sodium ascorbyl phosphate, magnesium ascorbyl phosphate, palmitoyl ascorbate and others stable ascorbic acid derivatives, and have a concentration of 0.2-10%. #CMT#ADMINISTRATION : #/CMT# Administration of the composition is topical, in a form of cream, lotion, gel, foam or spray or patch (claimed). No dosage details given. #CMT#EXAMPLE : #/CMT# Typical composition comprised of: 95.45% of oil-in-water emulsion; 3% of L-cysteamine; 1% of sodium ascorbyl phosphate; 0.5% of citric acid; and 0.05% of water. |
