COLOURING COMPOSITION FOR THE SKIN COMPRISING A SELF-TANNING AGENT AND A DYE OBTAINED BY REACTING AN AMINE WITH DEHYDROASCORBIC ACID OR A MONOMERIC POLYMERIC OR ISOMERIC DERIVATIVE THEREOF

摘要

A problem when using artificial sun tanning compositions incorporating DHA is the length of time the coloration takes to develop and the tendency to produce yellow shades that harm the production of a natural skin tone. It is possible to combine DHA with dyes, however the susceptibility of DHA with respect to coloured iron oxides, and water-soluble azo, quinone or xanthene dyes limits their use.
