| abstract |
The present invention relates to a material comprising tree molecules each consisting of at least bifunctional fragments and at least trifunctional fragments united to each other by ester or thioester bridges, alone or in combination with amide or urea bridges, said bridges being formed from two functions carried by different fragments, said molecules having, on the fragments located at the ends of the trees, terminal associative groups capable of associating with each other by hydrogen bonds and covalently connected to the functions It does not participate in said bridges. It also relates to its process of obtaining, as well as its uses and the compositions, in particular cosmetic, containing this material. |
