Abstract
A non-aerosol two-layer separate type hair cosmetic composition containing components (A) and (B) at a mass ratio (A)/(B) of from 0.2 to 10:
- (A) a silicone with a number-average degree of polymerization of from 300 to 20,000 having a number-average particle diameter of from 0.05 to 20 μm, selected from the group consisting of dimethicone, dimethiconol, and amino-modified silicone and in an amount of from 0.1 to 6 mass %
- (B) a water-soluble cationic polymer with a weight-average molecular weight of from 50,000 to 1,000,000, selected from the group consisting of polyquaternium-6, polyquaternium-7, polyquaternium-16, and polyquaternium-22,
- wherein the composition consists of an oil-in-water emulsion layer and an aqueous layer.
