Paraffin wax

New page

=Description=
Paraffin wax is the most widely used commercial wax. It is mainly derived from the high-boiling fractions of petroleum. It is commonly sold in slabs or blocks which exhibit crystallinity and various degrees of translucency. There is often a difference in melting point between the outside and inside of a slab because of nonhomogeneity. The crude paraffin waxes, containing varying amounts of volatile ingredients, are odorous and greasy. The refined grades are tasteless, odorless, harder and less greasy<ref>Bennett, H., Commercial Waxes, Second edition, p. 17</ref>.
