Description

Sucrose Acetate Isobutyrate (SAIB) is a high-purity, non-volatile, and non-crystallizing liquid ester derived from sucrose. This compound serves as a key food-grade additive and a versatile excipient in pharmaceutical formulations, prized for its excellent stabilizing and texturizing properties. It is essential for manufacturers in the food & beverage, pharmaceutical, and personal care industries seeking to improve product stability, mouthfeel, and controlled release characteristics.

Application

• Food & Beverage Industry: Primarily used as a weighting agent and stabilizer in citrus-flavored and other cloudy beverages to prevent ring formation and ensure uniform cloud dispersion.
• Pharmaceuticals: Employed as a non-aqueous vehicle and film-forming agent in controlled-release drug delivery systems, including oral suspensions and topical applications.
• Personal Care & Cosmetics: Functions as a film former, thickener, and binder in products like nail polish, hair sprays, and sunscreens to enhance durability and texture.
• Industrial Applications: Acts as a plasticizer and modifier in specialty coatings, adhesives, and printing inks to adjust viscosity and improve film properties.
• Confectionery: Used in the production of certain chewing gums and glazes to modify texture and provide a glossy finish.
