/kloc-at the end of 0/2, Europeans first melted beeswax with a hot soldering iron, directly rubbed it on the floor, and then polished the floor with manpower. Later, beeswax was heated and dissolved in turpentine, made into soft ointment and coated on the floor. After turpentine evaporates, the coating is polished. Waxing and polishing wooden furniture with this ointment began and prevailed in the European Renaissance in14 ~16th century. This ointment can be made into shoe polish by adding a proper amount of pigment. This kind of waxed product, which takes beeswax as the main raw material alone, has a soft wax film, which is not smooth enough and easy to attach dust, so the use effect is not ideal. 1797, Kossler discovered a natural plant hard wax-carnauba wax on palm leaves in Brazil. This kind of wax has high melting point (83 ~ 85℃), high hardness and good gloss after wiping, and was once known as "the king of wax". When it is added to waxed products, its quality of use is obviously improved. In the late19th century, this wax was widely used in the formulation of wax polishing products. 1885 American shoe polish manufacturer whitmore Brothers produced shoe polish containing carnauba wax. The earliest shoe polish and floor wax in China were "Huadong shoe polish" and "Huadong floor wax" produced by Shanghai Huadong Chemical Plant (now Shanghai No.3 Daily Chemical Plant) in 1930s.
