  • Patent number: 8771376
    Abstract: The invention relates to a composition for dyeing keratin materials, and in particular human keratin fibres such as the hair, comprising at least one 2-pyrrolidone functionalized in the 4 position with an ester or amide radical, and at least one hydrophobic direct dye or a pigment; a dyeing process using this composition. Similarly, the invention relates to the use of the said pyrrolidone combined with a direct dye or a pigment for dyeing keratin materials, and especially to the use of the said pyrrolidone for improving the colour uptake onto the fibres of direct dyes that are sparingly soluble or insoluble in aqueous-alcoholic supports. The invention also relates to novel pyrrolidone derivatives. The present invention makes it possible in particular to obtain direct dyeing on keratin materials that is fast, resistant to washing, chromatic and powerful.

  • Patent number: 6740127
    Abstract: The preparation for dyeing keratin fibers contains, in a cosmetic carrier, a combination of at least one 4,5-diaminopyrazole derivative of formula (I), or a physiologically compatible salt thereof. in which R is an alkyl group, a monohydroxyalkyl group, a polyhydroxyalkyl group, a monoaminoalkyl group, a polyaminoalkyl group, an unsubstituted benzyl group or a substituted benzyl group substituted with a halogen, an alkyl group or an alkoxy group; and at least one phenylurea derivative of formula (II), or a physiologically compatible salt thereof, in which R1 represents a hydroxyl or alkoxy group and R2 represents a hydrogen atom, a halogen atom, an alkyl group, an alkoxy group, a hydroxyalkyl group or polyhydroxyalkyl group, each with up to 6 carbon atoms. A method of hair dyeing with this preparation is described.

  • Patent number: 6482400
    Abstract: The invention relates to a cosmetic composition for coating keratin fibers, comprising a cationic polymer, an anionic polymer and an aqueous polyurethane dispersion. The invention also relates to a process for coating keratin fibers which consists in applying the composition to the keratin fibers. The composition leads rapidly to a uniform make-up result which has good properties of coating, lengthening and curling the eyelashes, as well as good staying power.
