Beeswax has a very stable chemical make-up and its properties remain unspoilt by time. It is resistant to hydrolysis and natural oxidization and is completely insoluble in water. Apart from the larvae of the wax moth, no animal has the digestive acids and juices to break it down. Beeswax is lipid by nature and contains saturated hydrocarbons, acids or hydroxy-acids, alcohols, pigments, mostly from pollen and propolis, as well as minute traces of brood etc. It is solid in appearance in normal temperatures, becomes brittle once the temperature drops below 18°C and quickly becomes soft and pliable at around 35° to 40° C. It has a density of approximately 0.95 and a melting point of around 65°C. The colour of beeswax changes with age, for example virgin wax is white but darkens rapidly as it ages, often becoming almost black. This colouring process is due to the presence of diverse substances in the combs. Pigmentation in the wax usually gives shades of yellow, orange and red through to brown. This difference in colouring has no significance as far as the quality of the wax is concerned. Therefore, any attempt to bleach wax (ozonisation, sulphuric acid, hydrogen peroxide, etc.), as was so often recommended in the past, is not only useless but is now considered dangerous and should be proscribed. Use it in lotions as an emulsifier, in body butters and lip balms. Healing, antiseptic, emollient and softening are just a few of the wonderful properties beeswax adds to a product.
