Abstract

L'invention concerne un gélifiant qui, lorsqu'il sert dans la préparation d'une composition à base d'huile et sous forme de gel, peut être dissout dans la composition à une température relativement faible et permet ainsi d'obtenir une composition sous forme de gel stable à températures élevées. Ce gélifiant pour bases huileuses contient au moins un N-acyle-L-(acide aminé) dialkyle amide de formule (1) : (1), (dans laquelle R1 et R2 représentent indépendamment l'un de l'autre un groupe hydrocarbure C1-26, R3 signifie un groupe hydrocarbure C7-10 et n est 1 ou 2), par exemple, de l'acide dibutylamide N-2-éthyle hexanoyle-L-glutamique, et au moins un alcool monohydrique de faible poids moléculaire, par ex., du 3-méthoxy-3-méthyle butanole. Utilisé dans la préparation d'une composition à base d'huile et sous forme de gel, ledit gélifiant peut être dissous à une température inférieure ou égale à 100 °C. On peut ainsi réaliser une préparation sous forme de gel, stable et sans sinérèse, même à températures élevées. La composition sous forme de gel ainsi obtenue a un très bel aspect, elle est transparente et elle peut être utilisée dans la production de parfums.
