DEFINITION

Classification: 524/478

At least one microcrystalline wax:

(under subclass 477) Subject matter wherein one of the solid hydrocarbons is a microcrystalline wax.

(1) Note. The term "microcrystalline wax" refers to a wax material which is obtained usually from the residual product of the vacuum distillation of lubricating oils. In general, microcrystalline waxes contain very minor quantities of straight chain paraffinic hydrocarbons.

(2) Note. To be place herein, the disclosure or claim must recite a "microcrystalline wax".
