Disclosed are methods of preparing thiol keratin-containing materials, comprising applying a mixture comprising one or more thiol compounds and a catalyst. Methods of preparing cross-linked keratin-containing materials by applying a mixture comprising one or more thiol compounds and an oxidizing agent are also disclosed. Methods of grafting monomeric and polymeric materials on keratin-containing materials to provide a covalent coating on keratin-containing materials are disclosed. A mixture comprising one or more thiol compounds is applied to the keratin-containing material sample. The keratin-containing material sample then comprises a plurality of free thiol groups. A monomer is optionally applied to the keratin-containing material sample to form a plurality of covalent bonds between the free thiol groups and the monomers. The disclosed grafting methods can be carried out with or without catalyst.

This invention relates to an oxidative hair cream composition that contains at least one oxidative hair cream ingredient and at least one thiophene azo colorant.

The present invention relates to formulations with active oxygen compounds that include active oxygen and other active ingredients for the purposes of care for and/or maintaining and preserving a healthy condition of skin and integumentary systems on the surface of the body of the organism and in the ears, healthy condition of finger- and toenails and of oral cavity, including its mucous membranes, teeth, interdental spaces and periodontal tissues (gingiva) in the oral cavity, i.e. the target areas of the organism. The formulation for skin and integumentary systems on the surface of the body and in the ears and for the finger- and toenails is in the form of a solution, gel, emulsion, lotion, milk, spray, cream, film dressing, liposomes and/or mycelia. The formulation for the oral cavity and related systems and structures, including teeth, interdental spaces and periodontal tissues (gingiva) is in the form of a solution, mouthwash, spray, gel, paste, emulsion, film dressing, liposomes and/or mycelia. These formulations are included in the device for its application on and/or into the said area of the organism.

A chewable composition for teeth-whitening comprising a first region and a second region separated by a barrier layer; the first region comprising carbamide peroxide having water content of about 2% or less, a wetting agent (e.g., glycerin), an anhydrous chewing gum base having water content of about 1% or less, an anhydrous fruit acid, and one or more gum additives; and the second region comprising a chewable composition comprising a gum base, a source of bicarbonate ion, and one or more gum additives. A kit comprising separate chewable compositions corresponding to the first and second regions, and methods for whitening teeth using the chewable composition are also provided.
