The stearic acid for the skin is subsequently poured into the distillation device’s boiling water. This mechanism collects the steam released during the fat’s boiling process and passes it through several cooling coils. 

Stearic acid, an intermediate component known as stearin, condenses on the walls as an effusion in response to a fast drop in temperature. A white waxy solid is produced once it has been further cooled. The end product is a white powder with a melting point of around 70 °C that is soluble in oils and alcohols but insoluble in water.
