Petrolatum wax, Fybrene, Protowax

New page

=Description=
Petrolatum (mineral jelly), freed from its liquid and semiliquid hydrocarbons, yields an amorphous, white, translucent, plastic wax. It is commercially available under the name of Protowax or Fybrene. Its plastic and noncrystalline properties make it very useful. It also has good oil-holding capacity and prevents leakage or sweating out of oils. Thus, it can replace ceresin and ozokerite, where their low melting point is not undesirable<ref>Bennett, H., Commercial Waxes, Second edition, p. 105</ref>.
