  • compositions that contained Pemulen TR-1 (a viscosity-increasing agent; a (meth)acrylic acid/alkyl ( eth )acrylate copolymer) exhibited markedly excellent skin sensation and state of dispersion as compared with the cosmetic compositions which did not contain this ingredient.
  • Pemulen TR-1 a viscosity-increasing agent; a (meth)acrylic acid/alkyl ( eth )acrylate copolymer
  • aqueous skin cosmetic compositions were prepared. Each of the obtained cosmetic compositions was applied to wet after- shower skin, and thereafter the skin was towel-dried. The compositions were evaluated in terms of ease of receiving in hands, ease of spreading over the body, and uniformity of the skin sensation. As a result, it was revealed that all the cosmetic compositions of Examples 32 through 35 were superior to the compositions that contained no viscosity- increasing agents. Table 9
