Decyl Oleate DO Emollient Ester -CAS 3687-45-4
Decyl Oleate (DO) is a high-purity synthetic ester emollient refined by advanced esterification reaction and multi-stage purification technology, which is a core functional raw material widely used in modern high-end cosmetic industry.
Different from traditional vegetable oils with heavy texture and poor spreadability, and mineral oils with poor skin affinity and easy to cause dull skin, DO has a unique long-chain ester molecular structure, which has silky smooth texture, excellent spreadability and fast skin absorption.

With excellent powder dispersing performance, it can effectively disperse cosmetic pigments, mineral powders and sunscreen agents, avoid powder agglomeration, floating powder and caking, greatly improve the ductility and fitting degree of makeup products, and make the base makeup more even and long-lasting.
The product has excellent chemical stability, can be perfectly compatible with various cosmetic raw materials such as vegetable oils, emulsifiers, silicones and active ingredients, no precipitation or delamination during long-term storage and high-temperature processing, no oxidation, no discoloration and no peculiar smell. It is mild and non-irritating, suitable for various skin types including sensitive skin and infant fragile skin, and is the core raw material for creating silky skincare, high-fitting makeup and mild care cosmetic formulas.
