Abstract

A cosmetic product for hair bleaching or hair dyeing comprises a first agent containing an alkali agent, a second agent containing hydrogen peroxide, and a nonaerosol foamer container for discharging a mixed solution thereof in the form of foam, the mixed solution containing 1 mass % or more of the components (A) and (B) in total, wherein a mass ratio (B)/(A) is 0.25 or more.
(A) 0.01 to 5 mass % of an anionic surfactant containing sulfuric acid group represented by the following formula

R—O—(CH 2 CH 2 O) n —[CH 2 CH(CH 3 )O] m —SO 3 M

wherein R represents a C 8-25 hydrocarbon group, n and m each represent an average number of moles added of 0 to 50, and M represents an alkali metal or NH 4 , and
(B) a polymer comprising a diallyl quaternary ammonium salt as a constitutional unit and having a charge density of 5.5 meq/g or more and 8.0 meq/g or less.

First claim

The invention claimed is:

1. A cosmetic product, comprising:
a first agent containing an alkali agent,
a second agent containing hydrogen peroxide, and
a nonaerosol foamer container configured to discharge a mixed solution of the first agent and the second agent in the form of foam, the mixed solution comprising 1 mass % or more of components (A) and (B) in total, wherein a mass ratio of component (B) to component (A), (B)/(A), is from 0.31 to 1.83:
(A) 0.01 to 5 mass % of an anionic surfactant represented by formula (1)
R—O—(CH 2 CH 2 O) n —[CH 2 CH(CH 3 )O] m -SO 3 M  (1)

wherein R represents a hydrocarbon group having 8 to 25 carbon atoms,
n represents an average number of moles added of from 0 to 50,
m represents an average number of moles added of from 0 to 50, and
M represents an alkali metal or NH 4 , and
(B) a copolymer of a diallyl quaternary ammonium salt and acrylic acid having a charge density of from 5.5 meq/g to 8.0 meq/g.

2. The cosmetic product according to claim 1 , further comprising a cationic surfactant as a component (C).

3. The cosmetic product according to claim 2 , wherein a content of component (C) in the mixed solution is from 0.05 mass % to 5 mass %.

4. The cosmetic product according to claim 1 , further comprising a higher alcohol as a component (D).

5. The cosmetic product according to claim 4 , wherein a content of component (D) in the mixed solution is from 0.05 mass % to 5 mass %.

6. The cosmetic product according to claim 1 , wherein component (B) has a charge density of from 5.9 meq/g to 6.5 meq/g.

7. The cosmetic product according to claim 1 , wherein a content of component (A) in the mixed solution is from 0.1 mass % to 2 mass %.

8. The cosmetic product according to claim 1 , wherein a content of component (B) in the mixed solution is from 0.1 mass % to 2 mass %.

9. The cosmetic product according to claim 1 , wherein the copolymer (B) consists of at least one diallyl quaternary ammonium salt and acrylic acid in polymerized form.

10. The cosmetic product according to claim 1 , wherein the nonaerosol container and the mixed solution are configured to discharge the foam with a volume of at least 33 mL per 7 g of mixed solution.

11. The cosmetic product according to claim 1 , wherein the nonaerosol container and the mixed solution are configured to discharge the foam with a volume of from 33 mL to 85 mL, per 7 g of mixed solution.

12. A method for bleaching or dyeing hair with the cosmetic product of claim 1 , the method comprising discharging the mixed solution of the first agent and the second agent from the nonaerosol foamer container in the form of foam, and applying the foam to hair.

13. A method according to claim 12 , wherein said applying is carried out by hand.

14. The method of claim 12 , wherein the foam has a volume of at least 33 mL per 7 g of mixed solution.

15. The method of claim 12 , wherein the foam has a volume of from 33 mL to 85 mL, per 7 g of mixed solution.

16. A cosmetic product, comprising:
a first agent containing an alkali agent,
a second agent containing hydrogen peroxide, and
a nonaerosol foamer container configured to discharge a mixed solution of the first agent and the second agent in the form of foam, the mixed solution comprising 1 mass % or more of components (A) and (B) in total, wherein a mass ratio of component (B) to component (A), (B)/(A), is from 0.30 to 2:
(A) 0.01 to 5 mass % of an anionic surfactant represented by formula (1)
R—O—(CH 2 CH 2 O) n —[CH 2 CH(CH 3 )O] m —SO 3 M  (1)

wherein R represents a hydrocarbon group having 8 to 25 carbon atoms,
n represents an average number of moles added of from 0 to 50,
m represents an average number of moles added of from 0 to 50, and
M represents an alkali metal or NH 4 , and
(B) a copolymer of a diallyl quaternary ammonium salt and acrylic acid having a charge density of from 5.5 meq/g to 8.0 meq/g.
