Abstract

La présente invention est relative à de nouveaux composés hybrides comprenant au moins une entité polyol (Po) -par exemple oligomère ou polymère- dans lequel au moins l'une des fonctions hydroxyles de Po est substituée par au moins une entité A qui peut être de nature variée, par exemple polymère (e.g. polyorganosiloxane-POS), hydrocarboné ou minéral. La rotule Ro entre cette entité Po et cette entité A est obtenue par 'click chemistry' et répond à la formule (II.1) ou (II.2), avec Z représentant -CH- ou -N-. A est une entité choisie dans le groupe comprenant les polyols différents de Po, les polyorganosiloxanes (POS) les polyalkylèneglycols, les polyamides, les polyesters, les polystyrènes, les alkyles, les alcényles, les alcynyles, les aryles et les combinaisons de ceux-ci; les matières minérales tels que la silice; et leurs combinaisons. Applications de ces composés hybrides à titre d'émulsifiants, notamment en cosmétique.
