L'Oreal

An aqueous, alcoholic or hydroalcholic composition containing one or more oligomers or prepolymers that are polymerized in-situ, while the oligomer(s) is in contact with the hair, for in-situ formation (polymerization) of a polymer. The oligomer compositions contain essentially no toxic, hazardous or harmful monomer(s), such as resorcinol.

Emulsions, solutions and coatings comprising nitrocellulose are stabilized against yellowing on thermal aging when treated with boric acid or borax or hydrogen peroxide or 0.1 to 0.5% by weight of a chlorinated hydantoin such as 1,3-dichloro 5,5-dimethylhydantoin (DCH). Boric acid or borax may be added as aqueous solutions during nitrocellulose manufacture. Combined treatments and/or additions of boric acid and DCH give optimum stabilization against yellowing.

Nail polish is disclosed, based upon a film-former, a resin component and a solvent system, containing as film-former and/or resin component an O-benzyl-N-hydroxyalkyl chitosan of the formula (I) The polish film obtained with the nail polish posesses a high luster, outstanding adhesion, as well as an increased hardness compared to nail polishes based upon nitro-cellulose, with even more sufficient elasticity. Also includd in the present invention are the new O-benzyl-N-hydroalkyl-chitosans of formula (I).

La présente invention a pour objet de nouvelles compositions pour le traitement cosmétique de fibres kératiniques telles que les cheveux, comprenant dans un milieu cosmétiquement acceptable au moins un monomère diélectrophile et au moins un amorceur radicalaire. L'invention concerne également un procédé de traitement de fibres kératiniques à partir de cette composition ainsi que son utilisation pour traiter lesdites fibres.

The present disclosure relates to a dyeing composition comprising, in an appropriate dyeing medium, at least one pigment and at least one electrophilic cyanoacrylate monomer of formula - in which R is chosen from alkyl radicals and alkoxyalkyl radicals. Dyeing kits comprising said compositions and processes using same are also disclosed.

A substantially transparent, liquid cleaning product for hard surfaces, comprising at least 15% by weight of a surfactant and one or more abrasive materials selected from the group consisting of polymers having a diameter of from 0.6 to 4 mm, natural materials having a diameter of from 0.05 to 4 mm, and mixtures thereof.

La présente invention a pour objet une émulsion eau-dans-l'huile qui comprend une phase aqueuse, au moins un tensio-actif et au moins un inhibiteur de polymérisation du monomère et une phase huileuse comprenant un ou plusieurs monomères cyanoacrylates.L'émulsion eau dans l'huile de la présente invention permet de faciliter l'application de monomères cyanoacrylates sur les fibres kératiniques.

A nail tip adhesive is made by the process of mixing cyanoacrylate and a vitamin fortifier in a proportion by weight in the range of 0.0001% to 0.1% vitamin-to-cyanoacrylate, wherein the shelf life of the cyanoacrylate is at least not substantially shortened by adding such vitamin. Such vitamin fortifier comprises at least one of vitamin A, vitamin D-3, vitamin E, vitamin K, vitamin B-1, vitamin B-2, vitamin B-6, vitamin B-12, vitamin C, niacinamide, folic acid, panthothenic acid, and biotin.
