Is polyacrylamide toxic for human?

Is polyacrylamide toxic? Many people who are new to this product have this question. To tell you that polyacrylamide itself is non-toxic, but the acrylamide used in the production process is toxic, to answer this question, first from its production process and production process to analyze.

The production of polyacrylamide is mainly made by aqueous solution polymerization -- colloidal sampling -- acrylamide aqueous solution, which is directly polymerized under the action of initiator. The dry powder is polymerized by 20-30% acrylamide aqueous solution in medium concentration, and the polymerized colloid is prepared by granulation, kneading, drying and crushing. There is also reverse phase suspension polymerization, which is the polymerization reaction of aqueous solution with small liquid acrylamide beads suspended in organic solution to obtain high molecular weight and instant polyacrylamide beads. In the production process, the reaction temperature and reaction time should be strictly controlled to make the reaction adequate and strictly control the residual amount of acrylamide. Acrylamide residues are generally controlled at less than 0.01%.

The following describes the toxicity of acrylamide: Acrylamide is a white crystalline chemical, is the raw material for the production of polyacrylamide, one Water Treatment Chemicals like Polyaluminum Chloride. the human body can be exposed to acrylamide through the digestive tract, respiratory tract, skin mucosa and other ways, drinking water is one of the important contact pathways, acrylamide into the body can be absorbed by the body through a variety of ways, which is the fastest absorption through the digestive tract. About 90% of acrylamide that enters the body is metabolized and only a small amount is excreted in its original form in the urine. When acrylamide enters the body, it binds to guanine on DNA in the body to form adducts, causing damage to genetic material and gene mutations.

Investigations of occupational and incidental exposure to acrylamide have shown that acrylamide has neurotoxic effects, but there is insufficient evidence that dietary intake of acrylamide is significantly associated with the development of certain tumors in humans.

Although polyacrylamide is non-toxic, due to the toxicity of acrylamide as the raw material for the production of polyacrylamide, it is recommended that you do not directly touch with your hands, let alone eat.
