D70 is a high-purity, dearomatized hydrocarbon solvent composed mainly of C11–C14 aliphatic hydrocarbons, including n-alkanes, isoalkanes, and cycloalkanes, with less than 2% aromatic content. It is a clear, colorless liquid with a high flash point (~75°C), low odor, and low volatility, making it suitable for applications requiring reduced aromatic exposure and improved worker safety. Classified as a UVCB substance, D70 is derived from petroleum. Its chemical stability and low toxicity profile make it ideal for use in controlled industrial environments
