The present patent application relates to novel surface-active cationic compounds, to their use, in particular as hair conditioning agent, to a cosmetic treatment method, in particular for the hair, employing the said compounds, and to the cosmetic or pharmaceutical compositions, in particular hair compositions, comprising the said surfactants.
摘要:
Disclosed herein are para-phenylenediamine compounds of formula (I), and their salts and solvates: wherein R1 and R2 form, together with the carbon atoms to which they are attached, a 4-, 5-, 6- or 7-membered ring, wherein the ring comprises carbon atoms and, optionally, one or two atoms chosen from oxygen and nitrogen, the ring being optionally substituted, with the proviso that when the ring comprises two atoms chosen from oxygen and nitrogen, these two atoms are non-adjacent. Compositions comprising these compounds and processes of making them, as well as processes and kits for dyeing keratin fibers are also disclosed.
摘要:
The invention relates to novel bis-para-phenylenediamine derivatives containing a pyrrolidyl group substituted with a cationic radical, to dye compositions containing them and to the process of dyeing keratin fibres using these compositions.The present invention makes it possible to obtain a chromatic, powerful, sparingly selective and colourfast coloration of keratin fibres.
摘要:
The present patent application relates to cosmetic compositions comprising cationic compounds of quaternary ammonium esters derived from 2-[2-(diethylamino)ethoxy]ethanol type, to the use of these cationic compounds, in particular as conditioning agent, to a cosmetic treatment method, in particular a hair treatment method, employing them and to the novel cationic compounds.
摘要:
Novel pyrrolidinyl-substituted para-phenylenediamine derivatives comprising a cationic radical, the dye compositions comprising them and the process for dyeing keratin fibers using these compositions, making it possible to obtain a chromatic, powerful, unselective and fast coloration of keratin fibers.
摘要:
