Abstract

A detergent comprising (A) a sulfobetaine type ampholytic surfactant, and (B) a quaternary ammonium cation-modified silicone. A mass ratio [(A)/(B)] of the component (A) to the component (B) is 0.1 or more and 1,000 or less.

First claim

The invention claimed is:

1. A detergent, comprising:
(A) laurylhydroxysultaine,
(B) a quaternary ammonium cation-modified silicone, and
(C) 3 to 10% by mass of at least one member selected from the group consisting of a polyoxyethylene alkyl ether, a polyoxypropylene alkyl ether, an alkyl glucoside, and an alkyl glyceryl ether,
wherein a mass ratio [(A)/(B)] of the component (A) to the component (B) is 1 or more and 100 or less, and
wherein the content of an anionic surfactant is 1.0% by mass or less,
wherein the component (B) is at least one member selected from the group consisting of
quaternium-80 and silicone quaternium-22,
wherein the content of the component (A) is 1% by mass or more and 30% by mass or less.

2. The detergent according to claim 1 , further comprising, as a component (A′), an ampholytic surfactant other than the component (A).

3. The detergent according to claim 1 , further comprising, as a component (B′), a silicone other than the component (B).

4. The detergent according to claim 1 , further comprising, as a component (D), a cationic surfactant.

5. The detergent according to claim 1 , which is a hair detergent.

6. A method for preventing entanglement of hair or fibers, the method comprising washing hair or fibers with the detergent of claim 1 .

7. A detergent, comprising:
(A) laurylhydroxysultaine, and
(B) a quaternary ammonium cation-modified silicone,
wherein a mass ratio [(A)/(B)] of the component (A) to the component (B) is 1 or more and 100 or less, and
wherein the content of an anionic surfactant is 0% by mass,
wherein the component (B) is at least one member selected from the group consisting of quaternium-80 and silicone quaternium-22,
wherein the content of the component (A) is 1% by mass or more and 30% by mass or less.

8. The detergent according to claim 7 , further comprising, as a component (A′), an ampholytic surfactant other than the component (A).

9. The detergent according to claim 7 , further comprising, as a component (B′), a silicone other than the component (B).

10. The detergent according to claim 7 , further comprising, as a component (C), a nonionic surfactant.

11. The detergent according to claim 7 , further comprising, as a component (D), a cationic surfactant.

12. The detergent according to claim 7 , which is a hair detergent.

13. A method for preventing entanglement of hair or fibers, the method comprising washing hair or fibers with the detergent of claim 7 .
