Composition comprising an oxidation dye precursor, a polycondensate of ethylene oxide and propylene oxide and a cationic polymer with a charge density of greater than or equal to 4 meq./g

摘要

The present invention relates to a dye composition comprising at least one oxidation dye precursor, at least one poly-condensate of ethylene oxide and propylene oxide having the following structure: H-(O-CH2-CH2)a-(O-CH(CH3)-CH2)b-(O-CH2-CH2)a-OH, in which a and a' range from 2 to 150 and b ranges from 1 to 100; and at least one cationic polymer with a charge density of greater than or equal to 4 meq./g. The invention also relates to a dyeing process using this composition after mixing with a composition comprising an oxidizing agent. Another subject of the invention is devices comprising at least two compartments, the first compartment comprising the above composition and the second compartment comprising a composition comprising at least one oxidizing agent.
