2-Propoxy-1-propanol

  • Glycol ether solvents
  • CAS 10215-30-2
  • IUPAC: 2-propoxypropan-1-ol

2-Propoxy-1-propanol (CAS 10215-30-2) appears in 1 of the 2,122 car-care products CarCareTruth tracks (as of August 2026). It is classified as a VOC.

At substance level this propylene glycol propyl ether isomer is classified H319 (causes serious eye irritation). It is not on California's Prop 65 list and is not classified as a carcinogen, asthmagen, or reproductive toxicant. In car-care products it appears at trace concentrations (≤0.25%) as a minor co-solvent.

2-Propoxy-1-propanol (CAS 10215-30-2) is a glycol ether co-solvent closely related to 1-propoxypropan-2-ol (CAS 1569-01-3) — both are propylene glycol propyl ether isomers differing in hydroxyl position. Used at trace concentrations (≤0.25%) in automotive cleaning formulations. At substance level, classified as Flam. Liq. 3 (H226) and Eye Irrit. 2 (H319). Not classified as an aquatic toxicant. Readily biodegradable. Found as a minor component in professional-grade engine degreasers alongside the more prevalent 1-propoxypropan-2-ol isomer.
