Microcrystalline wax

Microcrystalline wax (CAS 63231-60-7), also listed as E905 and known commercially as cera microcristallina, is a refined petroleum-derived wax distinguished from paraffin by its finer crystal structure and higher oil content.

Where is Microcrystalline wax used?

• Cosmetics: structure and firmness in lipsticks, balms and stick formulations
• Food: E905-grade surface coating on fresh produce, confectionery and cheese rinds to control moisture loss and extend shelf life
• Printing inks and packaging coatings: viscosity adjustment, rub resistance and gloss control
• Metalworking and industrial lubricants: base component in rust-preventive compounds
• It improves adhesion and flexibility compared to harder paraffin alternatives.

Good to know: Not to be confused with paraffin: finer crystal structure and higher oil content. Food-contact grades meet FCC and E905 specifications; cosmetic grades meet USP and Ph. Eur. standards.

Commercial specifications

• Melt point ranges typically 60 to 90 degrees Celsius
