The use of emollients on the face is a traditional way to protect the skin against cold injuries in cold climate countries like Finland, but their preventive effect against frostbite has been questioned. The purpose of this investigation was to define the thermal insulation and occlusivity of ointments in cold by using a skin model with a sweating hot plate. The properties of four different emollients were studied in both dry and humid conditions simulating transepidermal water loss, sweating, and a combination of sweating and drying. The thermal insulation of ointments applied on a dry surface was minimal. Evaporation of water from an oil-in-water cream caused significant cooling for 40 min after its application. The diffusion of water through the applied emollients changed their thermal effects depending on their composition and on the amount of water. Low input of water increased and high input diminished slightly the thermal resistance of ointments. The minimal or even negative thermal insulation of emollients in varying conditions gives them at best only a negligible and at worst a disadvantageous physical effect against cold.
