Beeswax is a bee product and it is the most important natural waxes because of its unique properties and useful applications in medicine, cosmetics, food, engineering and industry. Beeswax is available in two forms, yellow (Cera flava) and white (Cera alba). Yellow beeswax is made by melting honeycombs with hot water and filtering out impurities from the melt. White beeswax is made by bleaching yellow beeswax with potassium permanganate, active carbon or sunlight. Very pure beeswax is white, but the presence of pollen and other substances cause it to become yellow. Beeswaxes are a complex mixture of hydrocarbons, carboxylic acids, esters and alcohols. The aim of this study was to investigate a structural and thermal properties of different kinds of beewaxes (BW), domestic and commercial one. Structural properties of different beewaxes were analysed by using FTIR-ATR spectroscopy and surface properties were obtained by using the contact angle measurement. Thermal properties of beeswaxes were investigated with a differential scanning calorimetry (DSC) and thermogravimetry (TGA). The results indicates that impurities incorporated in beeswaxes has a great influence on the surface as well as their thermal properties. Higher hydrophylity of impurities contributes to lowering hydrophobity of beewaxes and lowering their thermal stability.
