- CAS 63231-60-7
Microcrystalline Wax (CAS 63231-60-7) appears in 1 of the 1,812 car-care products CarCareTruth tracks (as of June 2026).
Petroleum-derived wax, not classified as hazardous under GHS. Food-grade microcrystalline wax is FDA-permitted for food contact and used in cosmetics. Not a known skin sensitizer or irritant at use concentrations.
Microcrystalline wax is a petroleum-derived wax with a finer crystal structure than paraffin. In car waxes, it provides durability and flexibility that pure carnauba lacks — it bends with the paint rather than cracking in cold temperatures.
Often blended with carnauba in "hybrid" wax formulations to get carnauba's depth with synthetic durability. The resulting blend (carnauba + microcrystalline) gives the best of both worlds. Not biodegradable but non-toxic.
