Description

1,2,3-Propanetriol 1-Stearate 2,3-Bisacetate is a specialized glycerol derivative, also known as glyceryl 1-stearate 2,3-diacetate, with the CAS registry number 33599-07-4. This compound serves as a versatile intermediate and functional additive, valued for its unique combination of lipophilic and hydrophilic properties derived from its stearate and acetate groups. It is primarily sought after by manufacturers in the cosmetics, personal care, and specialty chemical industries for its emulsifying, conditioning, and solubilizing capabilities.

Application

• Cosmetic & Personal Care Formulations: Acts as a non-ionic emulsifier, emollient, and skin-conditioning agent in creams, lotions, and ointments.
• Pharmaceutical Excipient: Used as a solubilizer and bioavailability enhancer for poorly soluble active pharmaceutical ingredients (APIs).
• Food Additive & Flavor Carrier: Functions as a food-grade emulsifier and carrier for flavors and colors in specific food systems.
• Plasticizer & Lubricant: Serves as an internal lubricant and processing aid in polymer and resin manufacturing.
• Industrial Surfactant: Employed in the formulation of specialty detergents, textile auxiliaries, and agrochemicals.
• Chemical Synthesis Intermediate: A key building block for the synthesis of more complex glycerol esters and surfactants.
