Abstract: PROBLEM TO BE SOLVED: To obtain a pasting agent free from the troubles of aggregation, separation and precipitation in storage and having excellent storage stability by carrying out emulsion polymerization of a vinyl acetate solution produced by adding a vinyl acetate oligomer to vinyl acetate monomer. SOLUTION: An emulsion-type pasting base agent composed of a vinyl acetate polymer is produced by the emulsion polymerization of a vinyl acetate solution produced by adding a vinyl acetate oligomer to vinyl acetate monomer at a ratio of 0.01-5 ppm, preferably 0.1-3 ppm and containing a nonionic surfactant such as polyoxyethylene alkyl ether as an emulsifier in the presence of a polymerization initiator such as 2,2'-azobis(2-amidinopropane) at 40-120 deg.C and pH 3-9.

Abstract: PROBLEM TO BE SOLVED: To provide a collapsible particle collapsing in cleansing and rinsing process and affording a little skin inflammation and a cosmetic composition having remarkably excellent detergent and rinse out properties by including the same. SOLUTION: This collapsible particle comprises by cohesion of at least a part of mixtures of two or more kind of primary particles insoluble in water, and the cohesion of the collapsible particle is collapsed by the lowering of the concentration of water-soluble salt in the water-soluble salt including aqueous solution. The cosmetic composition includes 1 to 25 wt.% of the collapsible particles, >=1.0 wt.% of the water-soluble salts having concentration less than the saturated concentration, surfactants and water.
