Octyldodecyl isostearate

Octyldodecyl isostearate (CAS 93803-87-3) is a branched-chain ester derived from isostearic acid and octyldodecanol, used primarily as an emollient and skin-conditioning agent in cosmetic formulations. Its highly branched molecular structure resists crystallization, keeping formulations fluid and stable across a wide temperature range.

This stability provides a practical advantage for formulators managing shelf life and product consistency. It also functions as a lubricant and dispersing agent in various industrial applications. In personal care, it is used in color cosmetics, sunscreens, and skin creams.

The ester is ideal where a lightweight, non-greasy skin feel is required without compromising spreadability or pigment dispersion. Lip products and foundations benefit from its ability to wet and disperse pigments evenly while contributing a smooth application texture.

In lubricant formulations, it serves as a base fluid or additive where low-viscosity, oxidation-stable esters are preferred over mineral oil. Coating and adhesive manufacturers use it as a plasticizing component to improve flexibility and substrate wetting.

Octyldodecyl isostearate is supplied as a clear, pale liquid in drum and IBC quantities. Cosmetic-grade material meeting standard industry purity specifications is the most commonly traded form for high-end personal care applications.

Technical-grade variants are available for industrial lubricant and coating applications. The material is handled according to standard chemical safety protocols to ensure quality and performance across all manufacturing sectors.
