Propylene glycol dicaprylate/dicaprate

Propylene glycol dicaprylate/dicaprate (CAS 68583-51-7) is a diester of propylene glycol with caprylic and capric fatty acids, supplied as a clear, lightweight ester oil. It functions as an emollient carrier, solvent, and plasticizer across personal care, coatings, and industrial lubricant formulations. In cosmetics and skincare, it delivers active ingredients and UV filters into formulations while providing a dry, non-greasy skin feel. This improves consumer acceptance of lotions, serums, and sunscreens by reducing the heavy residue often associated with traditional oils.

Formulators in color cosmetics use it as a dispersing medium for pigments and lipophilic actives. Its low viscosity supports even distribution without heavy residue, making it ideal for high-performance makeup products and specialized skin treatments. In coatings and adhesive systems, it acts as a plasticizer and coalescent solvent, improving film flexibility and substrate adhesion. These properties are essential for maintaining the structural integrity and longevity of industrial surface applications.

Lubricant and metalworking formulators incorporate it as a base fluid or co-solvent where biodegradability and oxidative stability are procurement considerations. It offers a sustainable alternative to petroleum-based fluids in sensitive environments. Propylene glycol dicaprylate/dicaprate is supplied as a clear, low-viscosity liquid. Cosmetic-grade material is the standard commercial form, with supply conforming to typical ester purity specifications used in personal care procurement.

The material is available in drum and IBC quantities from oleochemical ester manufacturers and specialty ingredient distributors. It meets the rigorous demands of global supply chains requiring consistent quality and reliable technical documentation.
