No GHS classification established at typical formulation concentrations. Not listed as a skin sensitizer, respiratory sensitizer, or reproductive toxin. Used as a wetting co-solvent at 3–7% in penetrating-oil formulations.

2-Propanol, 1-(1-methyl-2-propoxyethoxy)- (CAS 29911-27-1) is a propylene-glycol-derived ether co-solvent used in penetrating-oil and lubricant formulations. It assists wetting of metal oxide surfaces and aids capillary penetration into corroded thread clearances alongside the primary petroleum-distillate carrier.

This compound is listed as a California VOC-exempt solvent under CARB's penetrant category rules — its exclusion from the CA VOC calculation accounts for the significant difference between the EPA-basis VOC (97.2%) and the CARB-basis VOC (24.1%) for CRC Screwloose 03060. No GHS classification is established at the mixture concentrations (3–7%) where it appears in typical penetrant formulas.
