Description
3,7-Dimethyloctane-1,7-diol is a branched-chain diol supplied under trade names including Hydroxyol and Hydroxyciol, and registered under FEMA 2586 for flavour applications. It carries no E-code designation. CAS 107-74-4 and EC 203-517-1 are the standard regulatory identifiers used across European trade documentation.
In personal care formulations, it functions as a humectant by retaining moisture within the skin matrix and serves as a solvent carrier for active ingredients, improving their distribution across the formulation. In flavour applications under FEMA 2586, it contributes to fragrance and taste profiles at controlled use levels. It is also evaluated as a carrier solvent in pharmaceutical and printing ink systems.
The material is available as a viscous liquid and is subject to REACH registration requirements for supply within the European Economic Area. Procurement teams should request supplier Safety Data Sheets confirming REACH compliance status and confirm suitability against FCC or Ph.Eur. standards depending on the intended application.
