Description
Hexylene glycol (CAS 107-41-5) is a short-chain diol also known commercially as Isol, Diolane, and Hexalene glycol, with the systematic shorthand 2-methyl-2,4-pentanediol. It carries no assigned E-code and is registered under EC 203-489-0. It is fully REACH-compliant and listed in major international chemical inventories.
In personal care formulations, hexylene glycol functions as a humectant and preservative booster, disrupting microbial cell membranes to enhance the efficacy of primary preservatives at concentrations typically between 0.5% and 5%. In coatings and polymer systems, it acts as a coalescing solvent and heat stabilizer, improving film formation and reducing thermal degradation during processing.
Hexylene glycol is available in technical and cosmetic grades as a slightly viscous liquid, supplied in drums and IBC containers. It meets REACH registration requirements and is referenced in cosmetic ingredient databases under INCI nomenclature. Buyers should confirm grade suitability against Ph.Eur. or internal specification requirements. HS code 29053910 applies for EU import and export classification.
