Paraffin Wax

Paraffin wax is the most commonly used commercial wax. It is derived by deoiling paraffin slack wax feedstock. It is commonly sold in liquid bulk, slabs, or prills in bags, which exhibit crystallinity and various degrees of translucency. The refined grades are tasteless, odorless, hard and have less than 0.5% oil content, by weight.
