WebCAS: 112-25-4. Mixture of ethylene glycol monoalkyl ethers. n-Hexylglycol is a clear, mobile, neutral, slightly hygroscopic liquid with a mild odor. It is miscible with all common solvents, e. g. alcohols, ketones, aldehydes, ethers, glycols and aromatic and aliphatic hydrocarbons. Its miscibility with water, however, is limited. WebGlycol Ethers. Glycol Ethers are a group of solvents based on alkyl ethers of ethylene glycol or propylene glycol commonly used in paints and cleaners. These solvents typically have a higher boiling point, together with the favorable solvent properties of lower-molecular weight ethers and alcohols.
