Description
A white or slightly yellowish Mineral wax prepared from purified and decolorized Ozocerite. Ceresin is refined by treating powdered ozocerite with concentrated Sulfuric acid then filtering through animal Charcoal. The resultant wax is similar to paraffin, but is harder and has a higher melting point. Ceresin is composed of a wide range of long chain saturated hydrocarbons ranging from C20 to C32. Ceresin is used for candles, textile and paper sizing, floor polish, waterproofing, shoe polishes, and leather coating.
