 The melting point of beeswax is not constant since the composition varies slightly with its origin. Various pharmacopoeias give a range of 61-66C or more commonly, 62-65 C. Its relative density at 15 C is 0.958 – 0.970 g/cm3 and its electrical resistance ranges from 5×1012 to 20×1012 Ohm m. Its thermal conductivity coefficient is 2.5 x d10-3 Jcm/s°Ccm2. The saponification value of beeswax is 85-100.
 Beeswax is an inert material with high plasticity at a relatively low temperature (around 32 C). Beeswax is also insoluble in water and resistant to many acids, but is soluble in most organic solvents such as ether, benzine, benzol, chloroform, and turpentine oil and after warming, in alcohol and fatty oils. Ghedda waxes from the Asian honeybee species are described as softer and more plastic. The melting point of wax from three Meliponid (stingless bee) species ranged between 64.6 and 66.5 C.
