ABSTRACT:
Thickened cosmetic compositions are provided based upon a thickening system that includes sclerotium gum and a hydrophobically-modified acrylate or methacrylate copolymer. The relative weight ratio of sclerotium gum to the polymer may range from about 1:1 to about 1:30. Compositions according to the present invention may also contain water-soluble vitamins. Interactive viscosity enhancement is particularly evident when free carboxylic groups present on the hydrophobically-modified acrylate or methacrylate copolymer are neutralized with a base thereby forming anionic carboxylate groups.
