A cosmetic composition and a method of preparing a cosmetic composition that includes mangiferin characterized as demonstrating soluble and chemically stable mangiferin, wherein stability includes resistance to crystallization of mangiferin that is independent of temperature and pH.
Compositions And Treatments For Keratinous Materials Providing Damage Protection And Sensorial Benefits
The present invention relates to a cosmetic treatment and processes for treating keratinous materials, in particular for altering the color of hair as in hair coloration, hair color lightening or removal, and treatment of artificially colored hair, wherein the composition can include at least one antioxidant, applied separately or combined or combinable with one or more components of a color altering system in amounts sufficient to confer protection when the treatment composition is applied to keratinous material and thereby enhance and protect one or more sensorial features, and preserve the mechanical properties and native amino acid structure of the keratinous material.
Tetrapeptides And A Method Of Use As An Antioxidant
A tetrapeptide having antioxidant activity is provided. The tetrapeptide has a structure comprising, in amino acid sequence from N-terminus to C-terminus: tryptophan-X-tyrosine-X; wherein X is arginine, lysine, histidine or any positively-charged amino acid derivative such as 5-hydroxylysine, ornithine, 2,4-diamino-butyrate and 2,3-diamino-propionate. Each amino acid of the sequence or its Homo-amino acid derivative is independently of the D configuration (D-stereoisomer) or of the L configuration (L-stereoisomer), and the C-terminal comprises one selected from the group consisting of carboxyl (—COOH), and carboxamide (—CONH). A composition stabilized to oxidation or having antioxidant activity and a method for attenuating effects of free radicals on a keratinous material are also provided.
Carrier System For Water-Soluble Active Ingredients
A water releasing composition in the form of an emulsion and process for using the composition are provided. The composition includes an aqueous phase and an oil phase. The aqueous phase includes at least one water-soluble active ingredient at a concentration by weight of from about 0.1% to about 20%, based upon weight of the composition. The oil phase includes dimethicone at a concentration by weight of about 1% to about 25%, and an emulsifying crosslinked siloxane elastomer at a concentration by weight of about 0.1% to about 20%, both based upon weight of the composition. The composition has a phase ratio of the aqueous phase to the oil phase of about 3.0 to about 12.0. The composition converts from an emulsion to a plurality of droplets upon application of shear.
