Polyacrylamide

Polyacrylamide (abbreviated as PAM or pAAM) is a polymer with the formula (-CH 2 CHCONH 2 -). It has a linear-chain structure. PAM is highly water-absorbent, forming a soft gel when hydrated. In 2008, an estimated 750,000,000 kg were produced, mainly for water treatment and the paper and mineral industries. [1] Physicochemical properties [ edit]

polyacrylamide - safe cosmetics

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 lotions, powders, and creams. [8] [9] [10] Daily exposure to acrylamide through cosmetics may exceed the amount that would result from smoking a pack of cigarettes a day (.95 vs .67micrograms/kg of body weight per day). [11]

Cationic polyacrylamide copolymers (PAMs): environmental half life determination in sludge-treated soil | Environmental Sciences Europe

Cationic polyacrylamide copolymers (PAMs) are used for sludge dewatering in municipal waste water treatment and might enter the environment by spreading of the sludge on agricultural land. Concern has been expressed since little is known about the degradation of PAMs in soils.

Polyacrylamide quantification methods in soil conservation studies

Polyacrylamide (PAM) application in soil conservation has gained rapid acceptance in recent years. Determination of PAM concentration in waters containing soil constitutes (defined as soil waters in this paper)¡ªsuch as runoff water, irrigation tail water, and soil solution and PAM content in soil matrix is important for improving PAM application efficiency, understanding PAM conditioning

Polyacrylamide

Polyacrylamide (PAAM) forms soft, cationic nondegradable hydrogels consisting of entangled polymer chains tethered to one another via cross-linkers [175]. Its hydrophilic nature results in a high capacity for swelling and tendency for cell (bacterial and mammalian) adhesion and migration, granuloma formation, and fibrosis in vivo[152,153,176
