DESCRIPTION
Emulsifier
Sodium polyacrylate is a synthetic polymer used mainly as a thickening agent, emulsion stabilizer and texturizer in cosmetic and personal care products. It works by forming a gel structure that suspends ingredients and gives formulations a creamy or jelly-like texture.
Practical formulation guide
Usage level: In cosmetic products: 0.5–2 % depending on the desired thickening effect and stability.
How to use and incorporate: Sprinkle slowly over stirring water (no lumps) and let hydrate 30–60 minutes. Neutralize with triethanolamine or sodium hydroxide to pH 5.5–7 to form the gel; add the neutralizer drop by drop.
Formulation tips:
- Carbomers lose viscosity with electrolytes and at acidic pH; add salts, extracts and acidic actives carefully.
- To suspend particles (exfoliants, beads), a thickener with yield value is required, such as carbomer or xanthan gum.
- Before scaling up, make a pilot batch and run a stability test (cycles at 4 / 25 / 45 °C/39 / 77 / 113 °F for 4 weeks, checking odor, color, pH, viscosity and separation) in the final packaging.
Compatibility: Check compatibility with surfactants and salts.
Storage: Store in a cool, dry place away from direct sunlight and moisture. Protect from direct light. Use opaque packaging.
Precautions: Avoid inhaling the powder. Powder spills with water are very slippery.
Technical information for formulators: This sheet describes industrial uses of the raw material in the development of cosmetic products. It is not an efficacy claim for any finished product. The person responsible for the formulation must validate the concentration, compatibility and claims of their product in accordance with applicable regulations.
