Abstract:
PURPOSE: Provided are cosmetic compositions for oxidation dyeing keratin fibers, such as human keratin fibers like hair, comprising, in a dyeing medium, (1) at least one oxidation dye, and (2) a combination comprising at least one cyclo homopolymer of dialkyldiallylammonium and at least one other particular quaternary polyammonium. CONSTITUTION: The composition for oxidation dyeing keratin fibres comprises, in an appropriate dyeing medium, at least one oxidation dye, and additionally comprises at least one cyclo homopolymer of dialkyldiallylammonium comprising, as a constituent of the chain, at least one unit of structure (I): at least one quaternary polyammonium polymer chosen from: (i) polymers comprising repeating units of formula(II) and (ii) polyquaternary ammonium polymers comprising repeating units of formula(lIl). In the formula(I), k and t, which may be identical or different, are each chosen from 0 and 1, with the proviso that the sum of k+t is equal to 1; R12, which may be identical or different, are each chosen from hydrogen atoms and methyl groups; R10 and R11, which may be identical or different, are each chosen from alkyl groups comprising from 1 to 22 carbon atoms, hydroxyalkyl groups, and C1-C4 amidoalkyl groups; R10 and R11, together with the nitrogen atom to which they are commonly bonded, may additionally form at least one heterocyclic group; and Y is an anion. In the formula(II), R1, R2, R3 and R4, which may be identical or different, are each chosen from alkyl groups comprising from 1 to 4 carbon atoms and hydroxyalkyl groups comprising from 1 to 4 carbon atoms; n and p, which may be identical or different, are each chosen from integers ranging from 2 to 20; and X is an anion chosen from anions derived from inorganic acids and anions derived from organic acids. And in the formula(3), p is an integer ranging from 1 to 6, D is chosen from direct bonds and -(CH2)r-CO- groups, wherein r is a number equal to 4 or 7, and X is an anion chosen from anions derived from inorganic acids and anions derived from organic acids.
