Hydrogen Peroxide

  • Oxidizers
  • CAS 7722-84-1
  • IUPAC: hydrogen peroxide

Hydrogen Peroxide (CAS 7722-84-1) appears in 4 of the 1,812 car-care products CarCareTruth tracks (as of June 2026). It is readily biodegradable.

Skin and eye irritant at consumer concentrations (H315, H319). At concentrations above 8%, carries H271 (oxidizer), H332 (harmful if inhaled). At trace concentrations (0.01–0.03%), classification thresholds may not be met at the mixture level. GHS-classified per concentration.

Hydrogen peroxide (H2O2, CAS 7722-84-1) is a ubiquitous oxidizing agent used in consumer products ranging from bleaching to cleaning to trace-concentration formula adjuncts. It decomposes rapidly to water and oxygen, leaving no persistent residue.

At trace concentrations (0.01–0.03% as found in some acid-based mineral deposit removers), hydrogen peroxide is below the typical GHS classification thresholds for mixture-level hazard classification.

They describe the ingredient itself; whether a hazard applies to a finished product depends on its concentration and how it's used.
