fluorescent dye, colouring compositions, keratin material coloring process, multi-component device and use of fluorescent dyes of heterocyclic thiol

摘要

fluorescent dye, colouring compounds, keratin material coloring process, multicomparting device and use of fluorescent dyes. This invention refers to a dye composition that includes a fluorescent dye of thiol! heterocyclic disulfide, and to a dyeing process that has a glazing effect on keratin materials, in particular keratin fibres, in particular human keratin fibres, such as hair,using this composition, it refers in a manner similar to the fluorescent dyes of new heterocyclic thiol/ disaffect and their uses in the citration of keratin materials. This composition makes it possible to have a visible and particularly resistant whitening effect on dark keratin fibres.
