The invention relates to a process for the cosmetic treatment of keratin fibres, in particular human keratin fibres such as the hair, implementing the application of a composition comprising at least one surfactant, and the application of a composition comprising a particular metal compound and a conditioning agent chosen from cationic surfactants and/or fatty alcohols.

It is an object of the present disclosure to provide a method for treating keratinous material, in particular human hair, wherein there is applied to the keratinous material a first composition (A) comprising (A1) one or more organic C.sub.1-C.sub.6 alkoxy silanes and/or condensation products thereof, and a second composition (B) comprising (B1) a first cellulose and (B2) a second cellulose different from the first cellulose (B1).

The present invention relates to a multiple-compartment device (1) composed of a closed envelop (2) divided in at least two distinct compartments (7a) and (7b) separated from one another by at least one internal frangible seal (8), wherein one of the compartments (7a) containing a composition (A), comprising one oxidation dye precursor, one anionic surfactant, one amphoteric surfactant chosen from betaine; and another one of the compartments (7b) containing an oxidizing composition (B) comprising at least one oxidizing agent.

The subject of the present invention is a process for treating keratin fibers using a) at least one silicone comprising at least one carboxylic acid anhydride group, b) at least one amino silicone, and c) at least one coloring agent chosen from pigments, direct dyes and mixtures thereof, the compounds a), b) and c) being applied together or separately, in one or more compositions.

A biological hair shape change composition including a macromolecular component, a small molecular component and an alkali agent component is provided. The macromolecular component includes a protease belonging to the class of alkaline proteases, and the small molecular component includes a peptide with reduction activity. Both the macromolecular component and the small molecular component are obtained from a fermentation product of Bacillus licheniformis and a keratin and/or keratin polymer-containing medium. Molecular weights of ingredients in the macromolecular component are greater than or equal to 3 kDa and are 3-1000 kDa, and molecular weights of ingredients in the small molecular component are less than 3 kDa and are 0.01-2.99 kDa.

The invention relates to poly(oligo(ethylene glycol) methacrylate) microgels, to the process for preparing same and the uses thereof in various fields of application such as optics, electronics, pharmacy and cosmetics.

These microgels have the advantage of being monodisperse, pH-responsive and temperature-responsive. They can carry magnetic nanoparticles or biologically active molecules. These microgels may also form transparent films, which have novel optical and electromechanical properties.

The subject of the present invention is the use of a combination of cellulose 2-[2-hydroxy-3-(trimethylammonio)propoxy]ethyl ether chloride and at least one amino acid, selected from arginine, lysine, histidine or at least one of the salts of these amino acids, in a bleaching powder in order to reduce the damage to keratin fibres caused by an oxidative bleaching treatment.

A cosmetic composition for improved dyeing of keratin fibers is described. The composition comprises alkoxylated organopolysiloxanes and alkoxylated glyceryl esters and/or optionally alkoxylated alkyl glyceryl ethers. The composition may comprise less than 40 wt % water, or may be anhydrous. The composition may further comprise a direct dye, and may be used for bleaching, lightening, or dyeing of keratin fibers.

A temporary hair dye composition contains a soap base and a pigment. A method for temporarily coloring hair comprises mixing the temporary hair dye composition including the soap base and the pigment with water to generate a foam, and then applying the foam to the hair.

To provide a dental composition wherein the acid buffering capacity can be attained and the acid resistance of the tooth substance can be improved while maintaining very high foul breath inhibition capacity. A dental composition including: ion sustained-release glass; and a carrier for supporting the ion sustained-release glass, wherein the ion sustained-release glass is fluoroaluminoborosilicate glass having a composition range of: 15% to 35% by mass SiO.sub.2; 15% to 30% by mass Al.sub.2O.sub.3; 5% to 20% by mass B.sub.2O.sub.3; 20% to 45% by mass SrO; 5% to 15% by mass F; and 0% to 10% by mass Na.sub.2O.
