摘要:
The invention concerns the use as direct dyeing agent of at least one tetra-azapentamethine compound, a dyeing composition comprising at least such a compound, as well as a method for dyeing keratinous fibers, in particular human keratinous fibers and more particularly hair, which consists in applying at least one composition comprising such a compound. The composition also concerns tetra-azapentamethine compounds of formula (I). The invention further concerns a method for bleaching such compounds, as well as bleaching keratinous fibers previously dyed therewith.

摘要:
The present disclosure relates to processes for synthesizing tetraazapentamethine compounds that comprise reacting at least one compound of azine type with at least one oxidizing agent. The disclosure also relates to processes for dyeing keratin fibers, for example human keratin fibers, that comprise using such synthetic processes.
摘要:
The present invention relates to a composition for dyeing keratin fibres, and in particular human keratin fibres such as the hair, containing, in a support that is suitable for dyeing, at least one oxidation dye precursor, characterized in that it comprises at least one alcohol oxidase enzyme and at least one substrate for the said enzyme. This patent application also relates to a process for dyeing keratin fibres, which consists in applying this composition, and also to a dyeing “kit”.
摘要:
This application relates to a dye composition for dyeing keratin fibers, for example human keratin fibers, such as hair, comprising, in an appropriate dyeing medium, at least one aldehyde precursor, at least one enzyme able to generate an aldehyde from the at least one aldehyde precursor and at least one heteroaromatic hydrazone. This application also concerns a method for dyeing keratin fibers using the dye composition, and a dye “kit” containing the dye composition.
摘要:
The invention concerns a composition for topical application for extemporaneous preparation, comprising ascorbic acid and a suitable support, the ascorbic acid being obtained by bringing at least one ascorbic acid precursor with the exception of its esters into contact with at least one enzyme that is capable of converting said precursor. It also concerns the use of one or more enzymes selected from L-galactono-1,4-lactone dehydrogenase, L-galactose dehydrogenase, L-sorbosone dehydrogenase, L-gulono-1,4-lactone oxidase and mixtures thereof, or of an extract comprising said enzyme, for the preparation of ascorbic acid for topical use, and a cosmetic method for treating the skin consisting of applying to the skin, either simultaneously or successively, at least one enzyme that can convert an ascorbic acid precursor into ascorbic acid, and at least one ascorbic acid precursor with the exception of its esters.
