  • Publication number: 20130136705
    Abstract: The present invention relates to a cosmetic composition comprising: a) a supramolecular oil (compound A) which can be obtained by reaction between an oil bearing at least one nucleophilic reactive function and a joining group capable of establishing hydrogen bonds, said joining group bearing a reactive function capable of reacting with the reactive function borne by the oil, and said joining group also comprising at least one unit of formula (Ia) or (Ib): b) a polyalkene-based supramolecular polymer (compound B) which can be obtained by reaction of a functionalized polyalkene polymer with a functionalized joining group, said joining group being capable of forming at least three H (hydrogen) bonds. The invention also relates to a cosmetic treatment process using said composition.

  • Publication number: 20100303931
    Abstract: A subject-matter of the present invention is a cosmetic composition expanded in volume, in the form of an oil-in-water emulsion, comprising an internal fatty phase and an external aqueous phase comprising at least one inulin modified by hydrophobic chains and at least two gelling agents for the aqueous phase, one of the two gelling agents being chosen from unmodified clays, in particular montmorillonites, hectorites, smectites, bentones or laponites, or cellulose polymers, such as hydroxyethylcellulose, hydroxypropylcellulose, methylcellulose, ethylhydroxyethylcellulose, carboxymethylcellulose and quaternized cellulose derivatives, and the other gelling agent being chosen from gums arabic, guar gum, xanthan derivatives, karaya gum or locust bean gum, the said internal fatty phase being present in a content ranging from 5 to 50% by weight.
