Abstract
Provided is a thickener composition comprising the polymerization product of an aromatic monomer, an amine functional monomer, and a hydrophobic, associative monomer. The thickener composition is capable of thickening various formulations at a pH of 6.0 or less. Also provided are personal care, household, and industrial formulations that include the thickener compositions.
Claims20
A thickener composition comprising
- a polymer, wherein the polymer is a polymerization product of an aromatic monomer, an amine monomer, and a hydrophobic monomer.
A composition for increasing the viscosity of a personal care, household, or industrial formulation having a pH at or below 6.0, the composition comprising
- a polymer, the polymer comprising from 20% to 30% of an aromatic monomer based on total monomer weight, 55% to 65% of an amine monomer based on total monomer weight, and 10% to 20% of a hydrophobic monomer based on total monomer weight.
