  • Patent number: 9918919
    Abstract: Described herein is a method of dyeing the hair. The method includes applying to the hair a hair color composition including one or more direct dye compounds and rinsing the hair with water. The one or more direct dye compounds each include a yellow chromophore, one or two permanent cations, one to four incipient cations, and one or more hydrophobic moieties. The incipient cations are pendant to the core structure and are neutral. The one or more direct dye compounds enter the hair shaft after the hair color composition is applied to the hair. The hair color composition has a pH of from about 7 to about 11. The pH of the hair after rinsing is from about 3.5 to about 6. The rinsing of the hair causes one or more of the one to four incipient cations to change from neutral to positively charged inside of the hair shaft.

  • Patent number: 9856439
    Abstract: This application relates to thiophene azo dyes for use as hueing agents, laundry care compositions comprising such thiophene azo dyes, processes for making such thiophene azo dyes, and laundry care compositions and methods of using the same. The thiophene azo dyes contain a formally charged moiety and are generally comprised of at least two components: at least one chromophore component and at least one polymeric component. Suitable chromophore components generally fluoresce blue, red, violet, or purple color when exposed to ultraviolet light, or they may absorb light to reflect these same shades. These thiophene azo dyes are advantageous in providing a hueing effect, for example, a whitening effect to fabrics, while not building up over time and causing undesirable blue discoloration to the treated fabrics. The thiophene azo dyes are also generally stable to bleaching agents used in laundry care compositions.

  • Patent number: 9839590
    Abstract: The present disclosure relates to compositions and methods for improving the quality and durability of color in artificially colored hair. The methods employ alkaline earth metal salts that act as a mordant (a fixing agent) with hair dye and salts of hydroxy-polycarboxylic acids, which act as chelators. Methods are described wherein the alkaline earth metal salts or the salts of hydroxy-polycarboxylic acids are used in a pre-color treatment (a treatment to the hair prior to artificial coloring), used as part of a coloring composition, and used in a post-color treatment (a treatment to the hair after artificial coloring).
