Sodium polyacrylate ( ACR, ASAP, or PAAS ), [1] : 233 also known as waterlock, is a sodium salt of polyacrylic acid with the chemical formula [−CH 2 −CH (CO 2 Na)−] n and has broad applications in consumer products. This super-absorbent polymer (SAP) has the ability to absorb 100 to 1000 times its mass in water.
In the dry powder form of Sodium Polyacrylate, the positively charged sodium ions are bound to the polyacrylate, however in aqueous solutions the sodium ions can dissociate. The presence of sodium cations allows the polymer to absorb a high amount of water. Applications Absorbent. PAA is widely used in dispersants.

Sodium polyacrylate is an example of a super-absorbing polymer. It is a cross-linked (network) polymer that contains sodium atoms. It absorbs water by a process called osmosis. When the (sodium-containing) polymer is placed in contact with water, there is a tendency for the sodium to distribute equally between the network and the water.
Sodium polyacrylate (SO-dee-um pol-ee-AK-ruh-late) is an odorless, grainy white powder. Its most impressive property is its ability to absorb large amounts of fluid, up to 800 times its volume of distilled water and lesser amounts of other liquid mixtures.
Sodium polyacrylate is a super-absorbent polymer that works as a thickener, and emulsifier in cosmetics. It increases the viscosity of products and improves their texture. Body care: It functions as a thickening agent, texture enhancer, film-forming agent, and emulsion stabilizer.
