Abstract
An aerosol hair cleansing agent comprising a hair cleansing agent stock solution containing a surfactant (A) containing an anionic surfactant (A1) and two or more nonionic polymers (B) having weight average molecular weights different from each other, and a propellant (C) containing carbon dioxide. The component (B) contains a nonionic polymer (B1) having a weight average molecular weight of 1,000,000 or more and 5,000,000 or less and contains a nonionic polymer (B2) having a weight average molecular weight of 10,000 or more and 200,000 or less.
Claims10
An aerosol hair cleansing agent comprising a hair cleansing agent stock solution comprising:
- 6 to 20 mass % of a surfactant (A) containing an anionic surfactant (A1), and
- 0.1 to 0.5 mass % of two or more nonionic polymers (B) having weight average molecular weights different from each other, and
- a propellant (C) containing carbon dioxide,
- wherein the component (B) contains a polyethylene glycol (B1) having a weight average molecular weight of 1,500,0000 or more and 3,500,000 or less and contains a polyethylene glycol-polypropylene glycol copolymer (B2) having a weight average molecular weight of 50,000 or more and 120,000 or less,
- wherein the ratio of (B2) to (B1) is 3.0 to 15, and
- wherein (A1) is one or more members selected from the group consisting of sodium laureth sulfate, ammonium laureth sulfate, and sodium cocoyl glutamate.
