Description

Glycerides, C8-21 And C8-21-Unsatd. Mono- And Di-, 2-(Acetyloxy)-3-Hydroxybutanedioates 2,3-Bis(Acetyloxy)Butanedioates is a specialized class of acetylated glyceride esters derived from mixed fatty acid chains. This compound is valued for its unique combination of lipophilic and hydrophilic properties, making it a versatile functional ingredient and intermediate. It is primarily sought by formulators in the personal care, cosmetics, and specialty chemical industries for its emulsifying, solubilizing, and skin-conditioning capabilities.

Application

• Cosmetic & Personal Care Formulations: Acts as a non-ionic emulsifier, emollient, and skin-conditioning agent in creams, lotions, and sunscreens.
• Pharmaceutical Excipients: Used as a solubilizer and bioavailability enhancer for poorly soluble active pharmaceutical ingredients (APIs).
• Specialty Polymer Additives: Functions as a plasticizer or compatibilizer in polymer blends and coatings to modify flexibility and processing.
• Food-Grade Additives (potential): May serve as an emulsifier or stabilizer in specific food systems, subject to regulatory approval and grade specification.
• Industrial Lubricants & Release Agents: Employed as a component in biodegradable lubricants and mold release formulations.
• Chemical Synthesis Intermediate: Provides a reactive platform for further esterification or transesterification reactions to create custom surfactants.
