Expertgel 412 is a copolymer presenting PEO/PPO/PEO blocks with organic linking. It is a thermosensitive gel, with reversible gelation. It behaves as a liquid at ambient temperature and jellifies when the temperature increases. Expertgel® 412 has a gelation temperature under 15°C and below 21°C. It is unaffected by pH changes.

LUBRAJEL BA hydrogel is a clathrate of glyceryl acrylate and glyceryl polyacrylate that encloses water molecules via hydrogen bonding and Van der Waals forces. As supplied, this product contains about 50 weight % water. Since it binds moisture and is a highly viscous gel, Lubrajel™ BA hydrogel is an ideal ingredient to provide moisture to the mouth.

KLUCEL EF PHARMA is a nonionic polymer that is completely soluble in both water and polar organic solvents like ethanol. This grade is the pharmaceutical version of Klucel EF and has a viscosity of 300-600.

PLASDON K29/32 polymer by Ashland Specialty Chemical acts as a rheology modifier. It is a stable, water-soluble polyvinylpyrrolidone that meets U.S., European and Japanese pharmacopoeia specifications for Povidone. It forms complexes with catechins, just as it does with many other compounds that cause discoloration of teeth. The polymer can be effectively used to bind and remove stains through hydrogen bonding with chemical compounds.
