Description

Propylene Glycol Dilaurate is a non-ionic, lipophilic diester derived from propylene glycol and lauric acid. This versatile chemical intermediate and functional additive is valued for its excellent emollient, lubricating, and solvent properties. It serves as a key ingredient for formulators in the personal care, cosmetics, pharmaceutical, and food industries seeking stable, non-greasy texture modifiers and carriers.

Application

• Cosmetic & Personal Care Formulations: Acts as a premium emollient, skin-conditioning agent, and opacifier in creams, lotions, lipsticks, and makeup products.
• Pharmaceutical Excipient: Used as a solubilizer, co-solvent, and lubricant in topical ointments, creams, and transdermal delivery systems.
• Food Industry Additive: Functions as an emulsifier, stabilizer, and texturizer (e.g., E477) in various food products, though specific grade compliance is essential.
• Industrial Lubricants & Release Agents: Serves as a biodegradable component in synthetic lubricants, mold release agents, and fiber lubricants.
• Plasticizer & Softener: Imparts flexibility and softness in certain polymer and resin applications.
• Chemical Synthesis Intermediate: Employed as a building block or reactant in specialized organic synthesis processes.
