The word polyacrylamide and the acronym “PAM” are generic chemistry terms, referring to a broad class of compounds.There are hundreds of specific PAM formulations. They vary in polymer chain length and number and kinds of functional group substitutions as well as molecular conformation, the most important conformation variation being linear or cross‐linked conformation.

Anionic polyacrylamide (PAM) has been sold since 1995 to reduce irrigation‐induced erosion and enhance infiltration. Its soil stabilizing and flocculating properties improve runoff water quality by reducing sediments, N, dissolved reactive phosphorus (DRP) and total P, chemical oxygen demand (COD), pesticides, weed seeds, and microorganisms in runoff.
Effectiveness of Polyacrylamide in Reducing Runoff and Soil Loss under Consecutive Rainfall Storms
The use of anionic polyacrylamide (PAM) as a soil conditioner could help prevent soil loss by water. In this study, we determined the effective granular PAM rate that best reduces runoff and soil
Polyacrylamide (abbreviated as PAM) is a polymer with the formula (-CH2CHCONH2-). 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

- Are acrylamide/acrylate copolymers safe?
- (report_AcrylamideAcrylatesCopolymers_032025). At the December 2021 meeting, the Expert Panel for Cosmetic Ingredient Review Safety (Panel) issued a Tentative Report for public comment with the conclusion that the acrylamide/acrylate copolymer ingredients reviewed in the safety assessment are safe in the present practices of use and concentration.
- Can acrylamide be used in cosmetics?
- The use of acrylamide is banned in cosmetics in the EU, and the EU also sets limits for the amount of residual acrylamide allowed in products containing polyacrylamide. How to Avoid?
- Avoid products with polyacrylamide, acrylamide, polyacrylate, polyquaternium or acrylate on the label. European Commission (2009). Closing: Acrylamide.
- Is octylacrylamide copolymer safe?
- It was a lot of material. The safety assessment is for 16 derived ingredients. It has a multiplicity of uses, and octylacrylamide copolymer is reported to be used in 160 formulations and the others less so. We have max use reported. These are large molecular weight molecules. Our motion is safe as used when formulated to be non-sensitizing. DR.
- Is acrylamide a copolymer?
- Specifically, each of these ingredients comprise a copolymer, polymerized from at least 1 acrylamide monomer and 1 acrylate monomer. The Expert Panel for Cosmetic Ingredient Safety (Panel) has previously reviewed the safety of several other polyacrylamides (Polyacrylate 2, Polyacrylamide, and Acrylamide/Sodium Acryloyldimethyltaurate Copolymer).
