    Abstract: Uniformly sized, fine particles of a polymer is produced by: (1) mixing (B) a nonionic organic compound being liquid at room temperature, having a solubility in water at 25 DEG C of 0.01 wt.% or larger and being compatible with (A) an oil-soluble, ethylenically unsaturated monomer, with the monomer (A) in an amount of 0.5 to 300 wt.% based on the monomer (A), (2) then adding the mixture of (A) and (B) to an aqueous dispersion of (C) particles of a seed polymer so as to make the mixture of (A) and (B) absorb onto the paricles (C) and (3) polymerizing the mixture of (A), (B) and (C) in the presence of an oil-soluble initiator for the polymerization to obtain said uniformly sized, fine particles.

    Abstract: A film-forming cosmetic composition useful as a facial pack, nail enamel, eye liner etc., which comprises a copolymer of vinyl alcohol and alkyl vinyl ether, being referred to simply as PVA/AVE, consisting of 98 to 80 mole% of vinyl alcohol monomer units and 2 to 20 mole% of linear or branched alkyl vinyl monomer units having from 1 to 6 carbon atoms.The molar ratio of the vinyl alcohol monomer units to the alkyl vinyl ether monomer units is in the range of from 95/5 to 85/15.The PVA/AVE according to the invention has no acetic groups with ester bonds in a molecule. Instead, there are alkyl or alkenyl groups having ether bonds which serve for steric hindrance for preventing gelation of an aqueous solution of such copolymer. From this reason, the PVA/AVE does not undergo any hydrolysis as time passes and is thus excellent in storage stability.

    Abstract: A hair rinse composition which comprises at least one cationic surface active agent and a decomposition derivative of a keratin material which have been dissolved or dispersed in a suitable solvent. The decomposition derivative is a member selected from hydrolysates of keratin material, alkali salts of decomposition products obtained by oxidation of keratin material, alkali salts of derivatives at a thiol group of decomposition products obtained by reduction of keratin material and a mixture thereof.
