摘要:
Primary intermediates for hair coloring compositions for oxidative dyeing of hair are compounds of formula (I): wherein R is selected from C1 to C5 alkyl or hydroxyalkyl, a C3 to C6 cyclic ring containing hetero atoms selected from O, S and N atoms, and -CH2-Ar where Ar is an aromatic ring wherein the aromatic ring may be substituted with one or two hydroxy C1 to C3 alkoxy, or amino groups.
摘要:
Primary intermediates for hair coloring compositions for oxidative dyeing of hair are compounds of the formula (1): where R1, and R2 are each individually selected from a hydrogen atom, a C1 to C3 alkyl group, a C1 to C5 mono or dihydroxyalkyl group; phenyl or benzyl optionally substituted with an alkoxy group, or R1, and R2 together with the nitrogen atom to which they are attached form a piperazine, piperidine, imidazole, or morpholine ring.

A two-part high aqueous-content system for oxidative coloration of hair utilizing an aqueous dye lotion formulation containing hydroxypropyl bisisostearamidopropyldimonium chloride conditioner, optionally with one or more surfactants.
摘要:
This invention relates to a method to facilitate the removal of adherent polymeric films from a hard surface occasioned by the evaporation of solvent from positions containing an anionic amphiphilic polymer, the method comprising incorporating a phosphate ester surfactant into the compositions, and washing the film from the surface to which it adheres.
