Gamma Poly-Glutamic Acid FOOD GRADE >90%

Gamma Poly-glutamic acid (γ-PGA) is a natural occurring, multi-functional, and

biodegradable biopolymer. It is produced through fermentation by Bacillus subtilis using glutamic acid. PGA is consists of glutamic acid monomers crosslinked between α-amino and γ-carboxyl groups, and the molecular weight of PGA is usually between 500~5,000 kDa. It is water-soluble, edible and non-toxictowards human, and is environment friendly. It has broad applications in the fields of medicine, food, cosmetics, and water treatment.

Gantrez MS-955

Gantrez MS-955 polymer is a mixed sodium and calcium salt of methyl vinyl ether and maleic anhydride copolymer supplied as a powder. The polymer is slowly soluble in water resulting in amber-colored solutions with high viscosity and adhesion. The cations form salt bridges which crosslink the polymer chains. It is a mixed sodium/calcium salt copolymer, can be used directly in the formulation of a denture adhesive. In denture adhesives the salts provide excellent wet adhesive strength and duration of hold.

Plasdone K-29/32

Plasdone K-29/32 polymer is a stable, water-soluble polyvinylpyrrolidone that meets U.S., European and Japanese pharmacopoeia specifications for Povidone. Plasdone K-29/32 polymer 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. The toothpaste, mouthwash and oral rinse formulations will show improved stain removal with the addition of Plasdone K-29/32 polymer up to 2 percent.

Properties Suppliers
Plasdone S-630

Plasdone S-630 polymer is 60:40 linear random copolymer of N-vinyl-2-pyrrolidone and vinyl acetate. Soluble in water and in many organic solvents, the polymer is substantive, and acts as a film-former. It is also used as a tablet binder for denture cleaning tablets. It provides high breaking force and low friability to cleaning tablets.
