| 20080235883 | Composition for the coloring of keratinous fibers comprising a halochromic compound, the dye corresponding to this compound, and methods of use thereof - Disclosed herein is the use, in the coloring of keratinous fibers, for example human keratinous fibers, such as the hair, of a composition comprising at least one compound chosen from the compounds of formula (I) comprising a cyclic group G including a ring H capable of opening, the dyes corresponding to the compounds of formula (I) wherein the ring H is open and the addition salts thereof: | 10-02-2008 |
| 20090094762 | COMPOSITIONS FOR TREATING HAIR AND METHODS OF USE - Compositions comprising one or more acid direct dyes and an organic solvent such as propylene carbonate are described. The compositions have an oil phase content of 5 percent by weight or less. The oil phase of the compositions can include a cyclopentasiloxane and dimethiconol. The compositions can be applied to hair that has been previously dyed with an oxidative hair dye composition to restore color to the hair. The compositions can also be applied to hair that has not been previously treated with an oxidative hair dye composition. Methods of applying these compositions to hair are also described. The methods involve applying the composition to wet hair, allowing the composition to remain on the hair, and subsequently rinsing the composition from the hair with water. The hair may be treated with a conditioner before applying the compositions to the hair. | 04-16-2009 |
| 20090094763 | COMPOSITIONS FOR TREATING KERATIN AND METHODS OF USE - Compositions comprising one or more acid direct dyes and an organic solvent such as propylene carbonate are described. The compositions can be applied to untreated hair or to hair that has been previously dyed with an oxidative hair dye composition to restore color to the hair. The compositions for treating hair can have an oil phase content of 5 percent by weight or less. The oil phase of the compositions can include a cyclopentasiloxane and dimethiconol. Methods of applying these compositions to hair are also described. The methods involve applying the composition to wet hair, allowing the composition to remain on the hair, and subsequently rinsing the composition from the hair with water. The hair may be treated with a conditioner before applying the compositions to the hair. The compositions can also be applied to the skin with or without rinsing to darken the skin tone. | 04-16-2009 |
| 20090260165 | Composition comprising a compound X and A compound Y, at least one of which is a silicone, and a hydrophobic direct dye - The present disclosure relates to a composition for coloring keratin fibers comprising

| 20090300858 | SEMI-PERMANENT HAIR COLOR COMPOSITION OF MATTER INCLUDING A WATERPROOF INGREDIENT - Disclosed is a semi-permanent hair dyeing composition using a waterproof coating agent, in particular, a semi-permanent hair dyeing composition comprising a water-soluble dye, an acid dye, acrylate copolymer as a waterproof coating agent and N-methyl pyrrolidone as a solvent in a certain amount. The semi-permanent hair dyeing composition of the present invention has an advantage in that although the composition is not washed out after the application to the hair, the water-soluble dye fastened to the hair surface is not melted down by rainwater or sweat, and thereby, it can prevent skin and clothes from being contaminated with the dye. | 12-10-2009 |
| 20100306929 | USE OF NATURAL DYES FOR COLORING HUMAN HAIR - The present invention relates to a hair colouring composition containing at least one natural dye, in particular at least one orcein, and at least one particular organic solvent. The invention also relates to a hair colouring method that comprises applying on the fibres a composition containing one or more natural dyes for a duration sufficiently long for obtaining the desired colour. The invention thus provides colourings that respect the nature of the hair while offering strong, low-selectivity and resistant nuances. | 12-09-2010 |
| 20160158130 | HAIR DYE COMPOSITION - A hair dye composition is characterized by containing (A) HC BLUE No. 2, (B) DISPERSE VIOLET 1, and (C) at least one of HC YELLOW No. 2 and HC YELLOW No. 4 and has a pH of 7-11. The mass ratio of the content of (A) HC BLUE No. 2 to the content of (B) DISPERSE VIOLET 1 is preferably 1 to 30. The hair dye composition preferably further contains (D) DISPERSE BLACK 9. | 06-09-2016 |
