Compositions containing retinoid and chromenone derivatives
The present invention relates to a composition including at least one retinoid and at least one chromenone derivative and the use thereof for the preparation of a cosmetic article to be used for the topical application to skin, hair or nails.
1. A composition comprising (i) from about 0.04 to about 2% by weight of retinol and (ii) from about 0.1 to about 2% by weight of at least one chromenone compound of Formula I
or salt thereof where:
R 1 and R 2 are identical or different, and are selected from the group consisting of H, —C(═O)—R 7 , —C(═O)—OR 7 , a straight-chain or branched C 1 - to C 20 -alkyl group, wherein the alkyl is optionally at least once interrupted by oxygen, a straight-chain or branched C 3 - to C 20 -alkenyl group, a straight-chain or branched C 1 - to C 20 -hydroxyalkyl or -di- or polyhydroxyalkyl group, where the hydroxyl group is bonded to a primary or secondary carbon atom of the alkyl, and wherein the alkyl is optionally at least once interrupted by oxygen, a C 3 - to C 10 -cycloalkyl group and a C 3 - to C 12 -cycloalkenyl group (where the cyclic group is optionally bridged by —(CH 2 ) n — group where n=1 to 3);
R 3 is H or a straight-chain or branched C 1 - to C 20 -alkyl group;
R 4 is H or —OR 8 ;
R 5 and R 6 are identical or different, and are selected from the group consisting of H or —OH, a straight-chain or branched C 1 - to C 20 -alkyl group (wherein the alkyl is optionally at least once interrupted by oxygen), a straight-chain or branched C 3 - to C 20 -alkenyl group, and a straight-chain or branched C 1 - to C 20 -hydroxyalkyl group, where the hydroxyl group is bonded to a primary or secondary carbon atom of the alkyl, and wherein the alkyl is optionally at least once interrupted by oxygen;
R 7 is selected from the group consisting of H, a straight-chain or branched C 1 - to C 20 -alkyl group, wherein the alkyl is optionally at least once interrupted by oxygen, a straight-chain or branched C 3 - to C 2 O-alkenyl group, and a straight-chain or branched C 1 - to C 20 -hydroxyalkyl or -di- or polyhydroxyalkyl group, where the hydroxyl group is bonded to a primary or secondary carbon atom of the alkyl and wherein the alkyl is optionally at least once interrupted by oxygen, and
R 8 is H or a straight-chain or branched C 1 - to C 20 -alkyl group.
2. A composition according to claim 1 , wherein R 5 and R 6 are H.
