Title (EN) AMPHIPHILIC CO-POLYMER CONJUGATES FOR A CONTROLLED RELEASE OF ACTIVE MOLECULES
(FR) CONJUGUES DE COPOLYMERES AMPHIPHILES POUR LA LIBERATION REGULEE DE MOLECULES ACTIVES
Abstract:
(EN) The present invention relates to the field of perfumery. More particularly, it concerns polyethylene or polypropylene based polymers comprising at least one &bgr;-oxy or &bgr;-thio carbonyl moiety capable of liberating a perfuming molecule such as, for example, an &agr;,&bgr;-unsaturated ketone, aldehyde or carboxylic ester. The present invention concerns also the use of said compounds in perfumery as well as the perfuming compositions or perfumed articles comprising the invention's compounds.
(FR) La présente invention concerne le domaine de la parfumerie. Plus particulièrement, elle concerne des polymères à base de polyéthylène ou de polypropylène comprenant au moins une fraction $g(b)-oxy ou $g(b)-thio carbonyle capable de libérer une molécule parfumante telle que, par exemple, une cétone $g(a),$g(b)-insaturée, un aldéhyde ou un ester carboxylique. La présente invention concerne également l'utilisation de ces composés en parfumerie ainsi que des compositions parfumantes ou des articles parfumés comprenant les composés de l'invention.
