Is polyacrylamide a stable polymer?

Polyacrylamide is a polymer of controllable molecular weight formed from the polymerization of acrylamide monomers, Polymers can have different chemical characteristics based on the pH at polymerization. Polyacrylamide is chemically inert in enzyme systems and generally is stable.

What is the impurity of polyacrylamide?

IMPURITIES The impurity of most concern in Polyacrylamide is the residual monomer, acryla- mide. Because of the documented neurotoxic effects and carcinogenicity of acryla- mide, the relevant information concerning the monomer is an important consideration in the safety assessment of Polyacrylamide.

Are modified polyacrylamide resins toxic?

The toxicity of modified Polyacrylamide resins has been tested in feeding studies using both rats and dogs. The number of animals in the studies was not indicated. The animals were given a maximum dose of 464 mg/kg body weight without any signs of toxicity in either species.

Does aqueous solution of polyacrylamide have high viscosity?

When using small quantities of this material, high viscosities may be obtained in aqueous systems.‘6,7’ A 1% aqueous solution of a cosmetic formulation containing Polyacrylamide had a pH of 6.5. Aqueous solutions of Polyacrylamide are stableover a pH range of 3 to 10, with little effect of viscosity.“’
