Description

Sucrose Acetate Isobutyrate (SAIB) is a high-purity, non-volatile, food-grade liquid ester derived from sucrose. This compound serves as a key weighting agent and stabilizer, prized for its ability to increase the density and viscosity of formulations while maintaining excellent clarity and stability. It is essential for manufacturers in the beverage, flavor, fragrance, and pharmaceutical industries seeking to create uniform, shelf-stable products with precise sensory characteristics.

Application

• Beverage Clouding Agent: Provides stable, uniform cloudiness and mouthfeel in fruit-flavored drinks and beverage concentrates.
• Flavor & Fragrance Fixative: Acts as a solvent and stabilizer in flavor oils and perfume compounds, controlling volatility and extending shelf life.
• Food Additive (Density Adjuster): Used as a weighting agent in citrus oil emulsions and other flavor delivery systems for beverages.
• Pharmaceutical Suspensions: Serves as a non-aqueous vehicle to stabilize active pharmaceutical ingredients in oral liquid suspensions.
• Cosmetic & Personal Care: Functions as a film-forming agent and plasticizer in nail polishes, hair sprays, and other cosmetic products.
• Industrial Coatings: Used as a specialty additive in coatings and inks to modify rheological properties and improve application performance.
