  • Patent number: 10729638
    Abstract: The purpose of the present invention is to solve the problem, in powder hair dye compositions that contain a percarbonate, that a change occurs in the dyed color tone before and after storage when the composition contains metaaminophenol, 5-aminoorthocresol, resorcin, or a salt thereof, as an oxidation dye. To solve the aforementioned problem, a powder hair dye composition containing (A) a percarbonate, (B) a starch, and (C) an oxidation dye is provided, characterized in that the composition contains at least 7 mass % starch (B) and in that the oxidation dye (C) contains at least one selected from metaaminophenol, 5-aminoorthocresol, resorcin, and salts thereof. Thus, a powder hair dye composition can be obtained which suppresses change in the dye color tone before and after storage and which has excellent storage stability.

  • Publication number: 20190175461
    Abstract: The purpose of the present invention is, in powder hair dye compositions that contain a percarbonate, to suppress deterioration of coatability in long-term storage and also to ameliorate hair stiffening after hair dyeing treatment. To solve the aforementioned problem, a powder hair dye composition containing (A) a percarbonate and (B) a water-soluble polymer compound is provided, characterized by containing, as the water-soluble polymer compound (B), microorganism-derived/produced mucilage or chitosan containing (b1) glucose as a constitutive sugar, and (b2) a starch. With this powder hair dye composition, it is possible to suppress reduction in coatability in long-term storage under high-temperature, high-humidity conditions, and also to ameliorate hair stiffness after hair dyeing treatment.

  • Patent number: 9707164
    Abstract: Provided is a powder hair dye composition capable of, in a hair-dyeing treatment intended to give a sharp black hue, suppressing the development of redness without being affected by the leave-on time required for the hair-dyeing treatment, while ensuring a sufficient hair-dyeing power. The powder hair dye composition contains (A) sodium percarbonate whose content is 1.8 to 3.7 mass % at the time of use, (B) p-phenylenediamine sulfate, and (C) m-aminophenol sulfate.
