Is PAM poisonous?

Is PAM poisonous? Many people who have just come into contact with this product have such questions. Tell everyone that PAM itself is non-toxic, but the acrylamide used in the production process is toxic. To solve this problem, first analyze it from its production process and production process.

The production of PAM is mainly carried out by aqueous solution polymerization - colloidal extraction - aqueous solution of acrylamide, which is directly polymerized by the initiator. The dry powder is polymerized by 20-30% aqueous solution of acrylamide. The colloid after polymerization is granulated. After the kneading, drying, and pulverization, the PAM is obtained, and the reversed-phase suspension is justified. The aqueous solution is suspended in an organic solution by a small liquid bead acrylamide to obtain a PAM bead having a high molecular weight and an instant solution. In the production process, the reaction temperature and reaction time should be strictly controlled to make the reaction sufficient, and the residual amount of acrylamide is strictly controlled. The residual of acrylamide is generally controlled to be less than 0.01%.

The following describes the toxicity of acrylamide: acrylamide is a white crystalline chemical. It is a raw material for the production of PAM. The human body can contact acrylamide through various routes such as the digestive tract, respiratory tract and skin mucosa. Drinking water is one of the important ways to contact. Acrylamide can be absorbed into the body through various ways, and the absorption through the digestive tract is the fastest. About 90% of the acrylamide entering the human body is metabolized, and only a small amount is excreted in the urine in the original form. When acrylamide enters the body, it combines with guanine on DNA to form an adduct, resulting in genetic material damage and genetic mutation.

Investigations into occupational exposure to acrylamide and accidental exposure to acrylamide have shown that acrylamide is neurotoxic, but there is insufficient evidence to suggest that acrylamide intake through food is significantly associated with the development of certain human tumors.

Although PAM is non-toxic, since acrylamide, a raw material for producing PAM, is toxic, it is recommended that you do not touch it directly or even eat it.
