ALKALI SOLUBLE LATEX THICKENERS |
摘要 |
Alkali soluble thickeners are dislcosed which comprise a reaction product of (A) an unsaturated carboxylic acid monomer, (B) a monoethylenically unsaturated monomer different from monomer (A), and (C) a hydrophobic, alkoxylated macromonomer polymerizable with monomers (A) and (B). The monoethylenically unsaturared monomer differe nt from monomer (A) comprises a methyl group, preferably is an acrylate and more preferably is methyl acrylate. The polymers disclose d solubilize at a pH of from about 4.5 to 6.0, thereby rendering the polymers particularly suitable for use in cosmetic compositions.
