Refined petroleum wax with small crystals. Binds oils, boosts plasticity and durability of color cosmetics, forms a thin occlusive film.
Topical application
CWeak evidence. In vitro data, open-label studies, or expert consensus.
Safe cosmetic-grade wax. Reactions are rare, contamination risk is minimized by pharmacopoeia standards.
Microcrystalline Wax is a petroleum-derived wax from heavy petroleum fractions. Differs from paraffin by smaller, tightly packed crystals and higher plasticity. Mechanism. A structurant and occlusive – forms a dense film on skin and hair, retains moisture. Thickens anhydrous systems (lipsticks, balms). Binds oils better than paraffin, prevents sweating. Where applied. Lipsticks, lip balms, stick deodorants, hair styling products, wax masks. Concentration 1–30%. Evidence base. No clinical RCTs required – a functional structurant. CIR confirmed safety. Safety. Hypoallergenic, non-comedogenic (0–1 comedogenicity), non-irritating. Pregnancy and lactation – topically safe.
