CA 2405735

The present invention is directed to a hair treatment preparation comprising a payload in an intimate relationship to a polymeric nanostructure, the polymeric nanostructure being reactive to hair or capable of being immobilized onto or in hair. The nanoscopic nature of the entities being engineered ensures three distinct characteristics. First, the imparted attribute can be either nearly permanent or semi-permanent, depending on the attachment chemistry. In the semi-permanent version, the intended effect can be controllably erased by removal of the nanostructure by simple chemical or physical means. Second, the nanoscopic entities are invisibly small. Their presence does not deteriorate the hand or feel of the hair. Third, the nano- technology approach is infinitely flexible and adaptable. It can be coupled with many existing dyes, colorants, UV absorbers, fragrances, softening agents and the like for hair treatment. Methods for treating hair with the hair treatment preparations of the invention are also encompassed.

La présente invention concerne une préparation de traitement capillaire, contenant une charge utile étroitement liée à une nanostructure polymérique, réagissant avec les cheveux et pouvant être immobilisée sur ou dans le cheveu. La nature nanoscopique desdites entités obtenues garantit trois caractéristiques distinctes. Premièrement, l'attribut transmis peut être soit presque permanent, soit semi-permanent, en fonction du processus chimique de fixation. Dans la version semi-permanente, l'effet souhaité peut être supprimé, de manière contrôlée, par le retrait de la nanostructure à l'aide d'un moyen chimique ou physique simple. Deuxièmement, les entités nanoscopiques sont si petites qu'elles sont invisibles. Leur présence n'altère pas le toucher de la chevelure. Troisièmement, la nanotechnologie est extrêmement flexible et adaptable. Elle peut être mise en oeuvre avec plusieurs teintures, colorants, absorbeurs d'UV, parfums, agents adoucissants et analogues, existants, destinés au traitement capillaire. L'invention concerne également des procédés de traitement capillaire à l'aide des préparations de traitement capillaire selon ladite invention.
