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.
Superabsorbent polymers are now commonly made from the polymerization of acrylic acid blended with sodium hydroxide in the presence of an initiator to form a poly-acrylic acid sodium salt (sometimes referred to as sodium polyacrylate). This polymer is the most common type of SAP made in the world today.
Furthermore, they are added to many foods and to concrete mixtures (superplasticizer). Some of the polyelectrolytes that appear on food labels are pectin, carrageenan, alginates, and carboxymethyl cellulose. All but the last are of natural origin. Finally, they are used in various materials, including cement.
Dosage of defoamer. A defoamer or an anti-foaming agent is a chemical additive that reduces and hinders the formation of foam in industrial process liquids.

The next time you're at a shelter, consider the dogs that need help the most. They need love! Like Ollie, a German Shepherd mix who seems to have "lost all hope" about finding a forever home.
Polycarboxylates are organic compounds with several carboxylic acid groups. Butane-1,2,3,4-tetracarboxylate is one example. Often, polycarboxylate refers to linear polymers with a high molecular mass (M r ≤ 100 000) and with many carboxylate groups. They are polymers of acrylic acid or copolymers of acrylic acid and maleic acid.
