Acrylamide vs. Polyacrylamide — What's the Difference?
By Tayyaba Rehman & Urooj Arif — Updated on May 10, 2024
Acrylamide is a toxic monomer used in industrial and scientific applications, while polyacrylamide is a polymer formed from acrylamide subunits, used primarily to stabilize and thicken substances.

Key Differences
Acrylamide is a chemical compound known for its use in the production of polyacrylamide and various industrial processes such as the manufacture of paper, dyes, and plastics. Polyacrylamide, on the other hand, is a polymer derived from acrylamide units, widely used as a flocculant in wastewater treatment and as a gel in electrophoresis for the separation of proteins.
While acrylamide itself is hazardous and recognized as a potential carcinogen, polyacrylamide is considered non-toxic in its polymerized form but can potentially release acrylamide under certain conditions. Whereas acrylamide requires careful handling due to its toxicity, polyacrylamide is generally safer but still requires prudent use due to the possible degradation back to acrylamide.
Acrylamide is typically handled in industrial settings with strict safety measures to avoid inhalation or skin contact. Conversely, polyacrylamide is used in various applications from agriculture to pharmaceuticals, where its ability to form hydrogels is highly valued for slow-release substances.
In terms of environmental impact, acrylamide can pose serious hazards if released into ecosystems, affecting water quality and aquatic life. Polyacrylamide is often used to improve soil structure and reduce erosion but must be monitored for its breakdown products, including acrylamide, which are environmentally concerning.

Is acrylamide dangerous to humans?
Yes, acrylamide is classified as a probable human carcinogen and is known to cause neurological damage if inhaled or absorbed through the skin.
What role does polyacrylamide play in water treatment?
It acts as a flocculant, helping to clump together suspended particles, making them easier to remove from water.
How are acrylamide and polyacrylamide related?
Polyacrylamide is synthesized from acrylamide monomers, linking many acrylamide units together to form long polymer chains.
How is polyacrylamide used in environmental management?
Polyacrylamide is used as a flocculant in water treatment processes and as a soil stabilizer to prevent erosion.
Can polyacrylamide be toxic?
Polyacrylamide is generally considered non-toxic, but it can potentially release toxic acrylamide under certain conditions such as high temperature or over time.
How is polyacrylamide disposed of?
Polyacrylamide disposal must be handled according to local environmental regulations to prevent its breakdown products from contaminating the environment.
How does acrylamide form in food?
Acrylamide can form in foods during high-temperature cooking processes, such as frying, roasting, or baking, particularly in starchy foods.
Why is acrylamide regulated in food and water?
