Abstract
A cosmetic composition for treating human keratin fibres, such as hair, comprising, in a cosmetically acceptable medium: (i) at least one reducing agent, and (ii) at least one aminosilicone comprising at least one aminoethylimino(C4-C8)alkyl group. Used for bleaching and permanently reshaping human keratin fibres. Processes, kits and devices for bleaching or permanently reshaping human keratin fibres using the composition.
Claims33
A cosmetic composition for treating human keratin fibres comprising, in a cosmetically acceptable medium:
- (i) at least one reducing agent, and
- (ii) at least one aminosilicone comprising at least one aminoethylimino(C4-C8)alkyl group, said composition being effective for treating human keratin fibres.
A process for preparing a composition comprising at least one aminosilicone comprising at least one aminoethylimino(C4-C8)alkyl group, said process comprising mixing extemporaneously, at the time of use, an anhydrous composition comprising at least one reducing agent with at least one aqueous composition, wherein at least one of the anhydrous and aqueous compositions comprises said at least one aminosilicone.
A process for bleaching or permanently reshaping human keratin fibres, said process comprising:
- (A) applying to the fibres a ready-to-use composition comprising, in a medium that is suitable for bleaching, at least one reducing agent and at least one aminosilicone comprising at least one aminoethylimino(C4-C8)alkyl group;
- (B) leaving said composition to act for an action time ranging from 1 to 60 minutes, optionally rinsing said fibres, optionally washing said fibres with a shampoo, optionally rinsing again, and optionally drying the fibre.
A multi-compartment device or kit for bleaching or permanently reshaping human keratin fibres, comprising multiple compartments, wherein a first compartment comprises at least one powder or at least one aqueous composition, and a second compartment comprises at least one aqueous composition, wherein at least one of the two compartments comprises at least one reducing agent and at least one of the two compartments comprises at least one aminosilicone comprising at least one aminoethylimino(C4-C8)alkyl group.
