Agent for altering the color of keratin fibers comprising a rheology modifying polymer and high levels of a fatty substance in a cream system

摘要

The present invention is drawn to an agent and process for altering the color of keratin fibers wherein the agent comprises: (A) a color base composition containing from about 50% to about 80% by weight of a fatty substance comprising a viscosity greater than about 50 mm2/s at 40° C.; and optionally, an additional fatty substance; a rheology modifying polymer; an alkalizing agent; a short alkyl chain hydroxy compound chosen from monoalcohols and polyols; an oxidative dye precursor; and an oxidizing composition comprising an oxidizing agent; and wherein the pH of the agent for altering the color of keratin fibers ranges from about 1 to about 7.

1. An agent for altering the color of keratin fibers comprising:
(A) a color base composition, containing, in a cosmetically acceptable medium:
(a) from about 50% to about 80% by weight of a fatty substance comprising:
(i) at least 5% by weight of at least one fatty substance having a viscosity greater than about 50 mm2/s at 40° C.; and(ii) from 0% to about 75% by weight of at least one additional fatty substance other than (A)(a)(i); all weights being based on the total weight of (A);
(b) at least one rheology modifying polymer selected from a crosslinked acrylate polymer in aqueous dispersion;(c) at least one alkalizing agent;(d) at least one short alkyl chain hydroxy compound chosen from monoalcohols and polyols;(e) at least one oxidative dye precursor; and (B) an oxidizing composition comprising, in a cosmetically acceptable medium, at least one oxidizing agent; and wherein the pH of the agent for altering the color of keratin fibers ranges from about 1 to about 7.
