What is Sodium Polyacrylate?
Sodium Polyacrylate is a superabsorbent polymer (SAP) commonly used for its ability to rapidly absorb and retain large volumes of liquid relative to its mass. It forms a stable gel upon hydration and is widely used in personal hygiene products like diapers and sanitary pads, as well as in moisture retention agents for agriculture, cable insulation, and spill control. It is valued for its high water-binding capacity, non-toxicity, and stability across a broad pH and temperature range.

EU Code: Not assigned (non-food polymer additive)

Advantages:

  • Superior absorbency for water and aqueous solutions
  • Maintains gel integrity under pressure
  • Non-toxic, non-corrosive, and biodegradable under controlled conditions
  • Cost-effective for industrial and consumer applications

Applications:

  • Baby diapers, adult incontinence products, and sanitary napkins
  • Soil conditioners and water-retaining agents in agriculture
  • Industrial absorbent pads and cable water blocking
  • Packaging moisture absorbers and spill kits

FAQs:

  • Is Sodium Polyacrylate food safe? No, it is not intended for ingestion
  • Is it biodegradable? Not readily biodegradable, though new formulations are improving this
  • Is it safe for skin contact? Yes, widely used in personal care under strict formulation control
  • Can it be reused? No, it is designed for one-time absorption
