Oxidative dye composition comprising polycondensate of ethylene oxide and propylene oxide and nonoxyalkylenated glycerolated nonionic surfactant

摘要

Disclosed is a dye composition comprising at least one oxidation dye precursor; at least one polycondensate of ethylene oxide and of propylene oxide having the structure (A) below: H(OCH2CH2)a(OCH(CH3)CH2)b(OCH2CH2)aOH (A), in which a and a range from 2 to 150 and b ranges from 1 to 100, and at least one non-oxyalkylenated mono- or polyglycerolated nonionic surfactant. The weight ratio of the non-oxyalkylenated mono- or polyglycerolated nonionic surfactant to the polycondensate of formula (A) ranges from 1 to 20. Also disclosed is a method for dyeing hair, comprising mixing the composition with a composition comprising an oxidizing agent, and applying the resultant mixture to hair. Further disclosed is a two-compartment device, the first compartment containing the composition, and the second compartment containing a composition comprising at least one oxidizing agent.
