Description

Propyleneglycoldicaprylate is a synthetic diester derived from propylene glycol and caprylic acid, valued for its excellent emollient and solvent properties. This high-purity chemical intermediate is crucial for formulators seeking a non-greasy, low-viscosity ingredient with superior skin feel and spreading characteristics. It is primarily used by manufacturers in the personal care, cosmetics, and pharmaceutical industries for creating premium topical formulations.

Application

• Personal Care & Cosmetics: Acts as a high-performance emollient and skin-conditioning agent in creams, lotions, sunscreens, and makeup products.
• Pharmaceutical Topicals: Serves as a solubilizer and penetration enhancer in ointments, gels, and transdermal drug delivery systems.
• Fragrance & Perfumery: Used as a solvent and fixative for essential oils and aromatic compounds, improving longevity and stability.
• Industrial Applications: Functions as a plasticizer, lubricant, or carrier fluid in specialty chemical formulations and polymer processing.
• Food-Grade Products: Employed as a carrier for flavors, colors, and fat-soluble vitamins in food supplements (subject to appropriate grade and certification).
