Ethylhexyl isononanate

Ethylhexyl isononanate (CAS 71566-49-9), also known commercially as 2-ethylhexyl isononanoate, is a branched-chain ester used across personal care and industrial formulations as an emollient and plasticizer.

Its low viscosity and excellent spreadability make it a preferred ingredient where skin feel, lubricity, or substrate wetting determines formulation performance in various commercial applications.

In personal care, it functions as a lightweight emollient in skin creams, sunscreens, and color cosmetics, delivering a non-greasy skin feel while improving pigment dispersion for better coverage.

Coating and adhesive formulators use it as a plasticizer to enhance flexibility and adhesion in films and sealant systems. It acts as a base fluid or additive carrier in lubricant applications.

In metalworking, it is utilized where low volatility and good lubricity on metal surfaces are required. It also serves as a solvent or dispersing medium for resins and active ingredients.

This chemical is highly valued in industrial formulations where compatibility with organic systems is a primary selection criterion. It is supplied as a clear, low-viscosity liquid in drum and IBC quantities.

Cosmetic-grade material meeting standard purity specifications is the most commonly traded form for personal care. Technical-grade supply is available for coatings, lubricants, and adhesive systems.
