Dioctyl ether

Dioctyl ether (CAS 629-82-3) is a symmetrical dialkyl ether derived from two octanol chains, commercially available under trade names including Cetiol OE and Antar. It carries no E-code designation and is also referenced as octyl ether or caprylic ether in formulation and procurement contexts.

In personal care formulations, dioctyl ether functions as a non-greasy emollient carrier, reducing the oily skin feel of heavier actives while improving spreadability without contributing to emulsion instability. In lubricant and metalworking applications, its ether linkage provides moderate lubricity and chemical stability under mechanical stress, making it suitable as a base fluid or co-solvent in cutting and forming fluids.

Dioctyl ether is supplied as a technical-grade clear liquid and falls under REACH registration requirements for EU market supply. It is classified under HS code 29091990 for customs purposes. Packaging formats typically include drums and intermediate bulk containers, with documentation available to support regulatory and formulation compliance requirements.
