    摘要: PURPOSE:A creamy or milky lotion cosmetic having improved emulsion stability, moisture retention, etc. during its use free from skin stimulation, containing a water-insoluble water absorbing polymer as an emulsifying agent obtained by polymerizing starch, a water-soluble polymerizable monomer and a crosslinking agent. CONSTITUTION:Starch is polymerized with a polymerizable monomer (e.g., acrylic acid) which is water-soluble or becomes water-soluble by hydrolysis and a crosslinking agent (e.g., 1,6-hexanediol diacrylic acid ester) in a weight ratio of 100:50-1,000:0.001-10 to give a water-insoluble water absorbing polymer. A creamy or milky lotion cosmetic containing this polymer as an emulsifying agent. The cosmetic has improved emulsion stability, viscosity stability, moisture retention during its use, water resistance, feeling, retention of makeup, etc. free from skin stimulation. The water-insoluble water absorbing polymer has particle diameters of about 100mu in dry time, water absorption capacity of at least 60ml/g, and the amount of the polymer used is 0.05-5.0wt% based on the total amount of prescription.
