Abstract
Official abstract text for this publication.
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—(O—CH 2 —CH 2 ) a —(O—CH(CH 3 )—CH 2 ) b —(O—CH 2 —CH 2 ) a′ —OH (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.
