Diisopropyl Adipate DIPA Emollient Ester-CAS 6938-94-9
Diisopropyl Adipate (DIPA) is a high-purity synthetic dibasic ester emollient refined by advanced esterification of adipic acid and isopropanol, combined with multi-stage rectification and purification technology.
It is a high-value dual-functional raw material widely used in modern cosmetic and personal care industries. Different from traditional ester emollients with high viscosity and sticky skin feel, and plasticizers with poor skin affinity, DIPA has a unique linear dibasic ester molecular structure, featuring ultra-low viscosity, excellent spreadability and fast skin absorption.
It can quickly penetrate into the stratum corneum without forming an occlusive film on the skin surface, keeping the skin fresh and breathable while providing mild moisturizing and softening effects. As a dual-functional ingredient, it not only acts as a refreshing emollient but also a high-efficiency cosmetic plasticizer, which can improve the flexibility and ductility of cosmetic formulas, prevent products from becoming hard and brittle during storage, and enhance the spreadability and fitting degree of makeup products.
The product has excellent chemical stability, good compatibility with various cosmetic raw materials such as vegetable oils, emulsifiers, sunscreen agents and silicones, no oxidation, no discoloration and no peculiar smell during long-term storage and high-temperature processing. It is mild, non-irritating, non-comedogenic and low-sensitizing, suitable for all skin types including sensitive skin and oily acne-prone skin, and is the core functional raw material for refreshing skincare, long-lasting makeup and mild care cosmetic formulas.

Frequently Asked Questions (FAQ)
• Q1: What is the core advantage of DIPA compared with ordinary dual-functional ester raw materials? A1: Ordinary dual-functional ester raw materials often have defects such as high viscosity, sticky skin feel or poor plasticizing effect. DIPA has ultra-low viscosity, refreshing and non-greasy skin feel, fast absorption, and at the same time has excellent emollient and plasticizing effects. It can balance skin feel and formula stability, and its comprehensive performance is far superior to ordinary dual-functional ester raw materials.
• Q2: What is the recommended formula addition ratio? A2: 2.0%-6.0% for daily skincare products, 4.0%-12.0% for color cosmetics and base makeup products, 3.0%-7.0% for sunscreen and makeup remover products, 1.0%-4.0% for hair care and baby care products, adjustable according to formula texture and functional requirements.
