Dibutoxymethane is an oligoether (more than one -O- grouping) or acetal containing two butyl groups and a methylene grouping. ^[1] It is used in cosmetics, as a cleansing agent, or solvent. It reduces the formation of soot and nitrogen oxides when added to diesel fuel. ^[2] It can be classed as a green solvent, as it contains no halogens, and is not very toxic. ^[3] Dibutoxymethane has also been used as a dry-cleaning solvent under the trade name SolvonK4, it dissolves both water-based and oil-based stains. ^[4]
