Phenoxyisopropanol

  • Alcohol solvents
  • CAS 770-35-4
  • IUPAC: 1-phenoxypropan-2-ol

Phenoxyisopropanol (CAS 770-35-4) appears in 1 of the 1,812 car-care products CarCareTruth tracks (as of June 2026). It is readily biodegradable.

Mild skin and eye irritant potential at high concentrations. At concentrations used in consumer fabric cleaners (typically <1%), no GHS health classification expected at product level.

Phenoxyisopropanol is an alcohol solvent and secondary antimicrobial co-agent used in household and personal care formulas at low concentrations. It functions both as a mild preservative and as a coupling solvent that helps keep the formula stable and clear. At the concentrations used in consumer fabric cleaners, it does not carry meaningful health or environmental hazard at product level. It is biodegradable. Some regulatory scrutiny applies to phenoxyethanol (a close structural analog) but phenoxyisopropanol has a lower reported sensitization potential in current literature.
