Abstract: An oxidation dye composition for keratin fibres, for example, human keratin fibres such as the hair, comprising, in a medium which is suitable for dyeing, at least one oxidation dye precursor and at least one nonionic amphiphilic polymer containing at least one fatty chain and at least one hydrophilic unit. Also disclosed are processes and dyeing kits using the oxidation dye composition.

Abstract: 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 cyclohomopolymer of dialkyldiallylammonium and at least one other particular quaternary polyammonium. Processes comprising such oxidation dyeing compositions.

Abstract: The invention relates to an oxidation dye composition for keratin fibres, and in particular for human keratin fibres such as the hair, comprising, in a medium which is suitable for dyeing, at least one oxidation dye precursor and optionally one or more couplers, characterized in that it also comprises a nonionic amphiphilic polymer containing at least one fatty chain and at least one hydrophilic unit. The invention also relates to the processes and dyeing devices using the said oxidation dye composition.

Abstract: The invention relates to an oxidation dye composition for keratin fibers, in particular for human keratin fibers such as the hair, this composition comprising, in a medium which is suitable for dyeing, at least one oxidation dye precursor and optionally one or more couplers, and also an anionic amphiphilic polymer containing at least one hydrophilic unit, and at least one allyl ether unit containing a fatty chain. The invention also relates to dyeing processes and dyeing devices using the oxidation composition.

Abstract: Cosmetic composition based on nonionic surfactants and cationic or amphoteric substantive polymers and its use as a dyeing or bleaching vehicle. The invention relates to a cosmetic composition containing, in a cosmetically acceptable medium: a) 14 to 50% of a mixture of nonionic surfactants chosen from oxyethylenated and/or oxypropylenated and/or polyglycerolated fatty alcohols which are linear or branched, the mixture comprising at least one surfactant A whose HLB in the sense used by Griffin is not less than 14, present at a weight concentration [A], and a nonionic surfactant B whose HLB value in the sense used by Griffin is not less than 1 and is less than 10, present in a weight quantity [B], more than one half of the nonionic surfactants present satisfying the inequality: 0.5≦R≦1.
