Sodium polyacrylate is a polymer that is a sodium salt obtained by polymerization of acrylic monomers. Sodium polyacrylate has various functions and applications, but there are also some potential hazards. The following is an introduction to the effects and hazards of sodium polyacrylate:
Function:
Dispersant: Sodium polyacrylate has excellent dispersion performance in aqueous solutions, which can evenly disperse solid particles or suspended substances in water, prevent their agglomeration, and maintain the stability of the dispersion system. Widely used as a dispersant in industries such as dyes, pigments, and coatings.
Sustained release agent: Sodium polyacrylate can adsorb active substances such as drugs and fertilizers, and control its release rate through slow release to achieve long-lasting and effective effects. This has led to its application as a sustained-release agent in fields such as medicine and agriculture.
Humectant: Sodium polyacrylate can adsorb and retain a large amount of water molecules, and is commonly used as a moisturizer in cosmetics and personal care products to provide skin moisturizing effects.
Hazards:
Irritation: High concentration sodium polyacrylate solution may be irritating to the skin and eyes, and protective measures should be taken when in contact.
Allergic reactions: Individual groups may have allergic reactions to sodium polyacrylate, such as skin itching, redness, and swelling, and should avoid contact.
Environmental impact: Large amounts of sodium polyacrylate discharged into water bodies may cause certain pollution to the water environment, and long-term accumulation may have adverse effects on the aquatic ecosystem.
Overall, the correct and reasonable use of sodium polyacrylate and the adherence to safe operating practices can effectively exert its effects and minimize potential hazards and risks.
