Abstract:
PROBLEM TO BE SOLVED: To obtain a new composition that produces new powerful dye in which properties of keratin fibers are valued and which brings about powerful, relatively nonselective and resistant dyeing results and provides various shades and that is derived from a plant extract and is used for dyeing keratin fibers by oxidizing dyeing. SOLUTION: This extract of Myrsine africana is used as a dye precursor for dyeing keratin fibers by oxidizing dyeing. Especially the extract of plant Myrsine africana is used for dyeing keratin fibers in oxidizing dyeing. This new composition contains the plant extract. This method for dyeing keratin fibers by oxidizing dyeing using the composition is provided. This colored substance is obtained by using the composition. COPYRIGHT: (C)2003,JPO

Abstract:
Composition for dyeing keratinic fibers comprises a heteroaromatic hydrazone, an aldehyde precursor and an enzyme capable of generating an aldehyde from the precursor. Independent claims are also included for: (1) dyeing keratinic fibers by applying the composition for a time sufficient for the desired color to develop; (2) kit comprising a composition containing the aldehyde precursor in one compartment and a composition containing the enzyme in another compartment, one or both compositions also containing the hydrazone.
