Description
2-Octyldodecanol is a branched-chain fatty alcohol derived from Guerbet condensation, commercially available under trade names including Eutanol G, Isofol 20, and Exxal 20. It carries no assigned E-code and is identified by CAS 5333-42-6 and EC 226-242-9. Its C20 branched structure distinguishes it from linear fatty alcohols.
In personal care formulations, 2-Octyldodecanol functions as an emollient by filling intercellular spaces in the stratum corneum, reducing transepidermal water loss without occlusion. In hair conditioners, its branched architecture prevents crystallisation at skin temperature, maintaining spreadability and delivering a non-greasy skin feel. It also serves as a carrier solvent for heat-sensitive active ingredients in pharmaceutical topicals.
The material is supplied in neat liquid form and is REACH-registered for the European market. It meets cosmetic-grade specifications aligned with INCI standards and is available in drums and IBC containers. No Ph.Eur. or FCC monograph applies; buyers should request a certificate of analysis confirming purity and colour specification.
