Polyacrylamide (IUPAC poly(2-propenamide) or poly(1-carbamoylethylene), abbreviated as PAM) is a polymer (-CH2CHCONH2-) formed from acrylamide subunits. It can be synthesized as a simple linear-chain structure or cross-linked, typically using N,N'-methylenebisacrylamide. In the cross-linked form, th

Polyanionic cellulose, or (PAC), is a safe thickening agent. PAC, a water soluble anionic polymer derived from cellulose, is comprised of the woody parts and cell walls of plants. It is chemically modified from natural cellulose and obtained water soluable cellulose ethers.

Xanthan gum is a polysaccharide with many industrial uses, including as a common food additive. It is an effective thickening agent and stabilizer to prevent ingredients from separating. It can be produced from simple sugars using a fermentation process, andderives its name from the species of bacte

Lifebuoys are often deployed on a variety of ships or on the shores of water to prevent danger. The lifebuoy can be paired with a quick release to eject the lifebuoy in an emergency.
