Polyacrylamide - Safe Cosmetics
Polyacrylamide is made up of repeating molecules of acrylamide, which is a suspected carcinogen. Trace amounts of acrylamide remain in polyacrylamide. Acrylamide is found in in lotions, powders and creams. [8],[9],[10] Daily exposure to

- Which comonomer is used for the production of anionic polyacrylamides?
- The workhorse comonomer for the production of anionic polyacrylamides is acrylate salts of acrylic acid. These anionic polymers can be prepared as various mono- and divalent metal salts and other positively charged inorganic and organic counterions of the polymerization of acrylic acid with acrylamide (see Fig. 34.4 ).
- What types of polyacrylamides are used in dewatering?
- Anionic, cationic, and nonionic polyacrylamides are used as coagulants and flocculants for the solid-liquid separations and enrichment of various minerals depending on the situation or application. The main processes that are used in dewatering include dewatering screens, sedimentation, filtering, and thermal drying.
- Does Pam solvated with Fe 3+ release acrylamide?
- It was found that PAM solvated with Fe 3+ generated ppb levels of acrylamide after exposure to sunlight under acidic conditions (pH 6). They concluded that release of acrylamide would be insignificant at low levels of iron (<0.02 mg/L) under alkaline (7.5–8.5) conditions.
