| Abstract: |
A two-part hair dye including a first part containing an alkali agent, a second part containing hydrogen peroxide, and a non-aerosol foamer container; wherein a liquid mixture contains Components (A) and (B) specified below, wherein the content of hydrogen peroxide in the liquid mixture is 3.60 mass % or higher, and the viscosity of the liquid mixture is 1 to 300 mPa·s. A method for dying hair, wherein a foam of the liquid mixture of the first part and the second part of the two-part hair dye is applied to hair, left to stand for 3 to 60 minutes, and then washed out. Component (A): oxidation dye; Component (B): 0.50 to 3.0 mass %, of polypropylene glycol having a weight-average molecular weight of 200 to 800. |

| Claim: |
1. A two-part hair dye comprising a first part comprising an alkali agent, a second part comprising hydrogen peroxide, and a non-aerosol foamer container for discharging a liquid mixture of the first part and the second part in the form of a foam, wherein the liquid mixture comprises components (A) and (B); component (A): an oxidation dye component (B): 0.50 to 3.0 mass % of polypropylene glycol having a weight-average molecular weight of 200 to 800, wherein the content of the hydrogen peroxide in the liquid mixture is 3.60 mass % or higher, and wherein a viscosity at 25° C. of the liquid mixture is 1 to 300 mPa·s. |
| Claim: |
2. The two-part hair dye according to claim 1, further comprising component (C) in the liquid mixture from 0.50 to 0.85 mass %, wherein the component (C) is a linear saturated aliphatic alcohol having 10 to 30 carbon atoms. |
| Claim: |
3. The two-part hair dye according to claim 1, wherein the oxidation dye comprises 0.050 to 0.50 mass % of para-aminophenol in the liquid mixture. |
| Claim: |
4. The two-part hair dye according to claim 1, wherein the total content of the Component (A) in the liquid mixture is 0.10 to 1.8 mass %. |
| Claim: |
5. A method for dyeing hair, comprising applying a liquid mixture of the first part and the second part of the two-part hair dye according to claim 1 in the form of a foam to hair, letting the hair dye to stand for 3 to 60 minutes, and, thereafter, washing the liquid mixture from the hair. |
| Claim: |
6. The two-part hair dye according to claim 2, wherein the oxidation dye comprises 0.050 to 0.50 mass % of para-aminophenol in the liquid mixture. |
| Claim: |
7. The two-part hair dye according to claim 2, wherein the total content of the Component (A) in the liquid mixture is 0.10 to 1.8 mass %. |
| Claim: |
8. The two-part hair dye according to claim 3, wherein the total content of the Component (A) in the liquid mixture is 0.10 to 1.8 mass %. |
