Description

Propylene Glycol Dicaprate is a high-purity diester derived from propylene glycol and capric acid. This compound serves as a versatile, non-toxic, and low-irritancy emollient and solvent, prized for its excellent skin feel and stability in demanding formulations. It is a critical ingredient for manufacturers in the personal care, cosmetics, and pharmaceutical industries seeking superior performance and regulatory compliance.

Application

• Cosmetic & Personal Care Formulations: Acts as a premium emollient, solvent, and carrier oil in skin creams, lotions, sunscreens, and makeup products.
• Pharmaceutical Excipient: Used as a solubilizer and penetration enhancer in topical drug delivery systems and ointments.
• Food-Grade Lubricant & Release Agent: Employed in food processing equipment and as a mold release agent where non-toxicity is paramount.
• Plasticizer for Polymers: Imparts flexibility and low-temperature performance to specialty polymers and resins.
• Industrial Solvent & Carrier: Functions as a safe and effective solvent for dyes, fragrances, and active ingredients in various industrial applications.
• Lubricant for Textile & Fiber Processing: Provides lubrication during fiber spinning and textile manufacturing to reduce breakage and improve quality.
