Description

  The present invention relates to a hair dye composition. In detail, it is related with the hair dye composition using the enzyme which can solubilize uric acid stably.

  Conventionally, uric acid has been used in hair cosmetics for the purpose of preventing dandruff, and external preparations for skin to prevent rough skin (for example, see Patent Documents 1 and 2). It is also applied to hair dyes using enzymes as uricase substrates (see, for example, Patent Document 3).

  However, since uric acid has very low solubility in water, cosmetics and hair dyes containing water have a problem that uric acid can be blended only in a trace amount. Moreover, even if it can mix | blend with a comparatively high compounding quantity, there exists a problem that the crystal | crystallization of uric acid precipitates with time.

  In order to solve such problems, a betaine-type amphoteric surfactant is blended, an aqueous cosmetic adjusted to a specific pH range (see Patent Document 4), an acrylic acid polymer, and a system. Aqueous cosmetics (see Patent Document 5) in which is adjusted to a specific pH range have been proposed.

  Although these techniques can suppress the precipitation of uric acid, the long-term storage stability is not fully satisfactory.

  On the other hand, starch derivatives such as hydroxypropyl starch phosphate have been reported to stabilize the viscosity of the preparation over time (see Patent Document 6), but have not been reported to suppress the precipitation of uric acid.
