What Is Sodium Polyacrylate?
Sodium polyacrylate is a versatile, synthetic polymer used as a film-forming agent, emulsion stabilizer, absorbent, thickening agent, and emollient. In its raw form it is a granular white powder.
Sodium polyacrylate belongs to a class of polymers called super absorbent polymers (or SAPs). It’s considered as such because of its ability to absorb 100–1000 times its mass in water. The independent Cosmetic Ingredient Review panel has ruled sodium polymethacrylate safe as used in cosmetics. Amounts between 0.3–1.4% are typically all it takes to achieve this ingredient’s many formulary traits.
In addition to its use as an absorbent in skin products, it is used in commercial applications, such as a gelling agent for disposable diapers and sanitary napkins. It is also a food additive to help thicken certain foods and preserve them for longer periods of time.
