Abstract
The invention relates to a molecularly imprinted polymer obtained by polymerization of a mixture comprising a basic ethylene monomer having an amine group, a crosslinking agent comprising at least 2 polymerizable ethylene unsaturations, a porogenic solvent and a C14-C20 fatty acid. A cosmetic composition comprising such a polymer. A cosmetic process to prevent and/or treat dandruff of the scalp using such a polymer.
Claims16
A cosmetic composition comprising an empty molecularly imprinted polymer prepared by:
- performing a polymerization of a pre-polymerization mixture comprising:
- i) at least one basic ethylene monomer comprising at least one amine group;
- ii) at least one crosslinking agent comprising at least two polymerizable ethylene unsaturations;
- iii) at least one porogenic solvent;
- and
- iv) at least one C14-C20 fatty acid, and
- removing the C14-C20 fatty acid present in the polymer obtained from the polymerization to form a polymer comprising empty imprints;
- and
- adding the polymer comprising empty imprints to a physiologically acceptable medium,
- wherein the cosmetic composition comprising an empty molecularly imprinted polymer is a final product suitable for topical application to the skin and/or scalp.
A process for preparing a cosmetic composition comprising an empty molecularly imprinted polymer comprising:

- i) at least one basic ethylene monomer comprising at least one amine group;
- ii) at least one crosslinking agent comprising at least two polymerizable ethylene unsaturations;
- iii) at least one porogenic solvent;
- and
- iv) at least one C14-C20 fatty acid, and
- removing the C14-C20 fatty acid present in the polymer obtained from the polymerization to form a polymer comprising empty imprints;
- and
- adding the polymer comprising empty imprints to a physiologically acceptable medium,
- wherein the cosmetic composition comprising an empty molecularly imprinted polymer is a final product suitable for topical application to the skin and/or scalp.
