Description

Propylene Glycol Dicaproate is a high-purity diester of propylene glycol and caproic acid, valued for its excellent solvency and low volatility. This compound serves as a versatile and effective intermediate and formulation component across multiple high-value industries. It is particularly sought after by manufacturers in the personal care, pharmaceutical, and specialty chemical sectors for its performance and stability.

Application

• As a solvent and carrier in topical pharmaceutical formulations and transdermal drug delivery systems.
• An effective emollient and skin-conditioning agent in cosmetic and personal care products like creams, lotions, and sunscreens.
• Used as a plasticizer for polymers and resins, enhancing flexibility and processing.
• A key intermediate and reactant in the synthesis of more complex specialty chemicals and esters.
• As a lubricant base and additive in specialty industrial lubricants and release agents.
• Employed in food-grade applications as a indirect food additive or processing aid where compliant grades are available.
• A co-solvent and stabilizer in agrochemical formulations for improved efficacy and shelf-life.
