Claims15
An oxidative hair cream composition, wherein the composition comprises:
- (a) at least one thiophene azo colorant according to Formula I:
- wherein at least one of the R11, R12, and R13 is an electro-withdrawing groups selected from halogens, nitro, nitrile, nitroso, —C(O)Rx, —C(O)ORy, —C(O)NRxRy, —OC(O)Rx, —OC(O)ORx, —OC(O)NRxRy, —S(O)2Rx, —S(O)2ORx, —P(O)2Rx, and —P(O)(ORx)2 groups;
- wherein R16, R17, R18 and R19 are independently selected from hydrogen, halogens, methyl group, ethyl groups, propyl groups, isopropyl group, n-butyl group, isobutyl groups, 2-butyl groups, tert-butyl groups, —(CH2)n—O—Rx, —(CH2)—NRxRy, —ORx, and —NRxRy, and at least one of R16, R17, R18, R19, R110 is —ORx, or —NRxRy;
- wherein two or more of R16, R17, R18, R19, R110 are connected to each other through covalent bonds to form a ring structure fused with the benzene ring in Formula I;
- wherein R110 is selected from the group consisting of hydrogen, deuterium and Rv;
- each Rv is independently selected from the group consisting of halogens, nitro, nitrile, alkyl, substituted alkyl, alkenyl, substituted alkenyl, aryl, substituted aryl, alkynyl, substituted alkynyl, —(CH2)n—O—Rx, —(CH2)—NRxRy, —C(O)Rx, —C(O)ORx, —C(O)O−, —C(O)NRxRy, —OC(O)Rx, —OC(O)ORx, —OC(O)NRxRy, —S(O)2Rx, —S(O)2ORx, —S(O)2O—, —S(O)2NRxRy, —NRxC(O)Ry, —NRxC(O)ORy, —NRxC(O)SRy, —NRxC(O)NRyRz, —ORx, —NRxRy, —P(O)2Rx, —P(O)(ORx)2, —P(O)(ORx)O−, and —P(O)(O−)2;
- wherein the index n is an integer from 0 to 4;
- and wherein Rx, Ry and Rz are independently selected from the group consisting of hydrogen, alkyl, substituted alkyl, alkenyl, substituted alkenyl, aryl, substituted aryl, alkynyl, substituted alkynyl, and Ru;
- Ru is an organic group composed of one or more organic monomers with said monomer molecular weights ranging from 28 to 500;
- and
- (b) at least one oxidative hair cream ingredient.
