Pharma Grade Petrolatum CHARACTERISTICS
Petroleum jelly is a mixture of hydrocarbons, having a melting point usually within a few degrees of human body temperature, approximately 37 °C (99 °F). It is flammable only when heated to liquid; then the fumes will light, not the liquid itself, so a wick material like leaves, bark, or small twigs is needed to ignite petroleum jelly.
