CA 2206463

A flavor, perfume, coolant or antimicrobial composition comprising a dimethicone copolyol selected from alkyl- and alkoxy-dimethicone copolyols having formula (I), wherein: X is selected from hydrogen, alkyl, alkoxy and acyl groups having from about 1 to about 16 carbon atoms, Y is selected from alkyl and alkoxy groups having from about 8 to about 22 carbon atoms, n is from about 0 to about 200, m is from about 1 to about 40, q is from about 1 to about 100, the molecular weight of the residue (C2H4O-)x(C3H6O-)yX is from about 50 to about 2000, and x and y are such that the weight ratio of oxyethylene:oxypropylene is from about 100:0 to about 0:100. The compositions provide improved surface residuality, impact and/or antimicrobial efficacy.

Composition aromatisée et parfumée, à propriétés refroidissantes ou antimicrobiennes, comprenant un copolyol de type diméthicone choisi parmi des copolyols de type alkyl- et alkoxydiméthicone de formule (I), où X est choisi dans le groupe suivant : hydrogène et alkyle, alkoxy et acyle ayant environ 1 à environ 16 atomes de carbone, Y est choisi dans le groupe suivant : alkyle et alkoxy ayant environ 8 à environ 22 atomes de carbone et n est compris entre environ 0 et environ 200, m est compris entre environ 1 et environ 40, q est compris entre environ 1 et environ 100, le poids moléculaire du résidu (C2H4O-)x(C3H6O-)yX est compris entre environ 50 et environ 2000, et x et y sont tels que le rapport pondéral oxyéthylène:oxypropylène est compris entre environ 100:0 et environ 0:100. Ces compositions donnent des caractéristiques améliorées de dépôt des résidus en surface et d'impact et (ou) d'efficacité antimicrobienne.
