Abstract

The present invention provides a dye remover composition performing destaining by the reduction action of a reducing agent, wherein the composition reduces the irritation to a scalp when applied to the scalp and is capable of preventing air oxidation after the destaining treatment. The dye remover composition is used for destaining fiber stained with an oxidation dye including a dye intermediate having an amino group, includes a reducing agent, and performs the destaining of fiber by the reduction action of the reducing agent. The dye remover composition further includes a reducing sugar. Examples of reducing sugar include xylose and dihydroxyacetone.

Claims

1. A dye remover composition used for destaining fiber stained with an oxidation dye including a dye intermediate having an amino group, the dye remover composition comprising:

a reducing agent, wherein the dye remover composition performs the destaining of fiber by the reduction action of the reducing agent; and

a reducing sugar,

wherein the reducing agent is at least one selected from the group consisting of an ascorbic acid, a thioglycolic acid, a cysteine, a mercapto compound, a sulfite, a bisulfite, and a thiosulfate.

2. The dye remover composition according to claim 1, wherein the reducing sugar is a monosaccharide.

3. The dye remover composition according to claim 2, wherein the monosaccharide is at least one selected from the group consisting of xylose and dihydroxyacetone.

5. The dye remover composition according to claim 1, further comprising a hair penetrant.

6. The dye remover composition according to claim 5, wherein the hair penetrant is an aromatic alcohol.

7. The dye remover composition according to claim 5, wherein the reducing sugar is xylose, and the mass ratio of xylose to the hair penetrant is in the range of 0.1 to 5.

8. The dye remover composition according to claim 1, wherein the reducing sugar is xylose, and the content of xylose in the dye remover composition is in the range of 0.5 to 30% by mass.

9. The dye remover composition according to claim 5, wherein the reducing sugar is dihydroxyacetone, and the mass ratio of dihydroxyacetone to the hair penetrant is in the range of 0.05 to 5.

10. The dye remover composition according to claim 1, wherein the reducing sugar is dihydroxyacetone, and the content of dihydroxyacetone in the dye remover composition is in the range of 0.05 to 30% by mass.
