"TSCA Definition 2008: A highly refined petroleum mineral oil consisting of a complex combination of hydrocarbons obtained from the intensive treatment of a petroleum fraction with sulfuric acid and oleum, or by hydrogenation, or by a combination of hydrogenation and acid treatment. Additional washing and treating steps may be included in the processing operation. It consists of saturated hydrocarbons having carbon numbers predominantly in the range of C15 through C50." [ChemIDplus] Ingestion can cause aspiration into the lungs; [ICSC] Inhalation of excessive severely refined mineral oil (SRMO) aerosols may induce an inflammatory response (exogenous lipid pneumonia, ELP) and possibly develop further to fibrosis; [ToxPlanet: EC: SCOEL] Acute effects include mild skin irritation and aspiration pneumonitis after ingestion; [Reference #1] May cause irritation; Aspiration may cause lipid pneumonia; [Sigma-Aldrich MSDS] See "Mineral oil, pure, highly and severely refined."
