Abstract
The present invention relates to hair coloring and hair bleaching compositions comprising at least one oxidizing agent and a specified cross linked amphoteric polymeric thickener and preferably a source of carbonate ion. The compositions surprisingly provide improved hair colorant and bleaching compositions which deliver improved lift, lightening and color delivery whilst minimizing damage which are easy to manufacture and have long shelf life stability.
Claims19
A hair colouring or bleaching composition comprising at least one oxidizing agent and at least one cross-linked amphoteric polymer, wherein said polymer comprises
- 1) at least one first monomer of formula (I)
- R1—CH═CR2—CO—Y1 (I)
- where R1 is independently selected from the group consisting of a hydrogen atom, a methyl radical and a COOH group, R2 is independently selected from the group consisting of a hydrogen atom, a methyl radical and a CH2COOH group, and Y1 is independently selected from an OH group or a NHC(CH3)2CH2SO3H group,
- 2) at least one second monomer selected from diallyldimethylammonium salt, 3-methyl-1-vinylimidazolium salt, or the monomers of formula (II)
- R3—CH═CR4—CO—Y2—(CnH2n)—N+(R5R6R7)A− (II)
- wherein R3 and R4, which are identical or different, are each selected from a hydrogen atom or a methyl radical;
- R5, R6 and R7, which are identical or different, are each selected from a linear or branched alkyl radical having from 1 to 6 carbon atoms;
- Y2 is selected from an NH group or an oxygen atom;
- n is an integer from 2 to 5;
- and A− is an anion selected from anions derived from organic or inorganic acids and
- 3) at least one cross-linking agent, wherein said polymer comprises from about 40 mol/% to about 80 mol/% of said first monomer, from about 20 mol/% to about 60 mol/% of said second monomer, and from about 0.01 mol/% to about 5 mol/% of said cross linking agent.
