Abstract
Abstract A hair cosmetic composition comprising fine particles of a crosslinked polymer, which are insoluble in water and ethanol and do not form a film at normal temperature, is disclosed. A conventionally known film-forming polymer may also be formulated optionally. The hair cosmetic is free from stiffness, stickiness, or excessive gloss imparted to the hair which are the defects of conventional hair cosmetics using only conventional film-forming polymers, and provides excellent hair conditioning and hair-resetting effects.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
52 words
A hair cosmetic composition comprising fine particles of a crosslinked polymer which is derived from a monofunctional oil-soluble monomer having one ethylenically unsaturated bond, of which polymer having a glass transition point of not higher than 300°K, are insoluble in water and ethanol, and do not form a film at normal temperature.
Claim 2
Dependent Claim
52 words
A hair cosmetic composition comprising fine particles of a crosslinked polymer which is derived from a monofunctional oil-soluble monomer having one ethylenically unsaturated bond, of which polymer having a glass transition point of not higher than 300°K, are insoluble in water and ethanol, and do not form a film at normal temperature.
Claim 3
Dependent Claim
42 words
The hair cosmetic composition as claimed in Claim 1, wherein said fine particles of the crosslinked polymer are prepared by copolymerizing said monofunctional oil-soluble monomer having one ethylenically unsaturated bond and a polyfunctional oil-soluble monomer having two or more ethylenically unsaturated bonds.
Claim 4
Dependent Claim
28 words
The hair cosmetic composition as claimed in Claim 1, wherein the weight average particle size of said fine particles of the crosslinked polymer is 0.1 - 10 µm.
Claim 5
Dependent Claim
43 words
A hair cosmetic composition as claimed in either one of Claims 1 - 3, wherein said fine particles of a crosslinked polymer have an adhesion of 8 - 100 g.f/cm and modulus of elasticity of 5 × 10⁵ - 30 × 10⁵ dyn/cm².
Claim 6
Dependent Claim
58 words
The hair cosmetic composition comprising: (A) fine particles of a crosslinked polymer which is derived from a monofunctional oil-soluble monomer having one ethylenically unsaturated bond, of which polymer having a glass transition point of not higher than 300°K, are insoluble in water and ethanol, and do not form a film at normal temperature, and (B) a film-forming polymer.
Claim 7
Dependent Claim
58 words
The hair cosmetic composition comprising: (A) fine particles of a crosslinked polymer which is derived from a monofunctional oil-soluble monomer having one ethylenically unsaturated bond, of which polymer having a glass transition point of not higher than 300°K, are insoluble in water and ethanol, and do not form a film at normal temperature, and (B) a film-forming polymer.
Claim 8
Dependent Claim
33 words
The hair cosmetic composition as claimed in Claim 5, wherein the content of component (A) is 0.1 - 10% by weight and the content of component (B) is 0.1 - 10% by weight.
