Abstract Petrolatum-like products are prepared by combining a distillate lubricating oil, a slack wax derived from a distillate lubricating oil and a wax crystal modifying additive having an intrinsic viscosity in the range of about 0.05 to about 0.3 dl/g and selected from the group consisting of amorphous polyethylene, amorphous polypropylene, copolymers thereof, halogenated homopolymers and copolymers thereof, and copolymers of 3 to 40 molar proportions of ethylene per molar proportion of an ethylenically unsaturated monomer having the general formula: WHEREIN X is selected from the group consisting of hydrogen, halogens and C1 to C5 alkyl groups; Y is selected from the group consisting of -OOCR, -OOCR and -COR groups; Z is selected from the group consisting of -COOR and -R; and R is selected from the group consisting of hydrogen and C1 to C10 alkyl groups.
The composition of claim 1, wherein said lubricating oil has a boiling range of about 650*F. to about 1150*F. A.E.T. and a viscosity at 210*F. in the range of about 40 to about 180 SUS and said wax is a slack wax having a melting point in the range of about 100*F. to about 170*F. and a viscosity at 210*F. in the range of about 35 SUS to about 80 SUS. derived from a distillate lubricating oil having a boiling range of about 650*F. to about 1150*F. A.E.T.
