Described herein are oral care compositions, and in particular to oral care mouth rinse compositions comprising a single source of stannous, wherein the single source of stannous is stannous oxalate; a tertiary amine fluoride; and at least one of a monocarboxylic acid, dicarboxylic, or a tricarboxylic acid, as well as to methods of using and of making these compositions. The present compositions are formulated to present stable, non-turbid compositions and are useful for preventing and treating diseases or conditions of the oral cavity.

A substantially non-aqueous, stable, lyophilic dermatological concentrate comprised of: (i) a hydroxy acid, preferably selected from the group consisting of (a) azelaic acid at a concentration of at least about 20% or (b), ascorbic acid, at a concentration of up to about 30%; (ii) glycerin; and (ii) hyaluronan and/or an alginate, and derivatives thereof.

A method of protecting hair from damage by applying a long-chain unhydrolyzed alkyltrialkoxysilane to hair shafts and then hydrolyzing and polymerizing the alkyltrialkoxysilane to form a non-penetrating outer layer on the hair shaft by utilizing pH adjusted water followed by the application of heat. Alternatively, the alkyltrialkoxysilane may be applied to the hair in combination with an alkyl or alkenyl succinic anhydride prior to the application of heat.

Cosmetic agents for treating keratinic fibers and methods for the reductive decolorization of dyed keratinic fibers are provided herein. In an embodiment, a cosmetic agent for treating keratinic fibers includes (a) one or more metal salts chosen from the group of tin(II) salts, iron(II) salts, manganese(II) salts, titanium(II) salts, or titanium(III) salts and (b) water. The agent has a pH between about 1.0 and about 3.0.

The present invention relates to a liquid composition for enriching aqueous or hydro-alcoholic food, cosmetic and/or dermatological products. The invention also relates to the use of said liquid composition and to the method for producing said liquid composition.
