Thus, the compositions will be expected to have wide utility irrespective of the sexes and ages.Type: GrantFiled: June 5, 1989Date of Patent: February 19, 1991Assignee: Kao CorporationInventors: Hiroshi Ando, Keiichi Akimoto

Patent number: 4935032Abstract: Method for dyeing human hair, comprising the steps of applying to hair a composition the temperature of which is higher than 30.degree. C. and lower than 50.degree. C. and which contains at least one nitro dyestuff of the benzene series supersaturated relative to its solubility limit at ambient temperature in a cosmetic medium suitable for dyeing hair and chosen from the dyestuffs having a ratio KC lim greater than 2 is aqueous solution, KC lim being the ratio of the limiting concentrations of the dyestuff in an aqueous medium which are measured at 50.degree. C. and 18.degree. C.; maintaining this composition in contact with hair either at ambient temperature or at a temperature above room temperature and below 50.degree. C., and rinsing the hair.Type: GrantFiled: July 1, 1985Date of Patent: June 19, 1990Assignee: L'OrealInventor: Jean F. Grollier
