Hexoxyethanol (2-hexyloxyethanol, CAS 112-25-4) is a mid-chain glycol ether used as a co-solvent in aqueous cleaning formulations. It improves solubility of oily soils and helps keep the formula stable. Compared to shorter-chain glycol ethers (such as 2-butoxyethanol), hexoxyethanol has lower acute toxicity at consumer-use concentrations. It is a VOC under EPA and most state definitions (not exempt under EPA Method 24 for aerosol propellants) and contributes to the product's non-exempt VOC total.
