Food Thickener, Stabilizer, & Emulsifier (E466)

Controls viscosity and prevents syneresis in beverages, sauces, and dressings. Crucial for inhibiting ice crystal growth in frozen desserts (e.g., ice cream) to ensure a smooth texture

Pharmaceuticals Excipient

Functions as a binder for tablet and capsule formulations, a disintegrant to aid tablet dissolution, and a suspension stabilizer and viscosity modifier for oral syrups, ophthalmic solutions, and topical gels

Oilfield & Drilling

Used as a fluid loss control additive and viscosity modifier in water-based drilling muds

Construction

Water retention functional agent in cement, plasters, and mortars to improve workability and curing

Specialty Binder

Temporary binder in the manufacture of ceramics, paper sizing, and Lithium-ion battery anodes

BPC Rheology Modifier

Provides viscosity control and stability in shampoos, body washes, and creams. Acts as a film-former and conditioning agent in hair care and as a binder in toothpastes
