Description

1,4:3,6-Dianhydro-D-Glucitol Monostearate is a high-purity, non-ionic surfactant and emulsifier derived from isosorbide and stearic acid. This compound is valued for its excellent biocompatibility, stability, and surface-active properties, making it a versatile functional ingredient. It is primarily sought after by manufacturers in the pharmaceutical, personal care, and specialty chemical industries for formulating advanced delivery systems and stable emulsions.

Application

• Pharmaceutical Excipient: Used as a solubilizer, emulsifier, or co-emulsifier in oral and topical drug formulations, including self-emulsifying drug delivery systems (SEDDS).
• Cosmetic & Personal Care: Acts as a non-irritating emulsifier and stabilizer in creams, lotions, and sunscreens, enhancing texture and product shelf-life.
• Food Additive (where approved): Functions as an emulsifier and stabilizer in certain food-grade applications, though specific regulatory compliance should be verified.
• Polymer & Resin Additive: Serves as an internal lubricant or processing aid in biodegradable polymers and specialty resins.
• Industrial Surfactant: Employed in specialty cleaning formulations, agrochemicals, and coatings where a biodegradable, non-ionic surfactant is required.
