What You Need to Know
When beeswax melts (62–64 °C) and is applied at ~70 °C, it coats the surface, creating a low‑polarity film that limits moisture loss and oxygen ingress. The film’s barrier properties inhibit microbial growth and oxidation, while the wax’s inherent antimicrobial esters provide additional protection.
The Science
Primary Reaction
Formation of a semi‑occlusive wax film reducing water activity and oxygen diffusion
