Claim 1

A COMPOSITION OF MATTER CONSISTING ESSENTIALLY OF MICROCRYSTALLINE WAX MELTING IN THE RANGE OF 120* F. TO 165* F. AND A REFINED MINERAL OIL IN SUCH PROPORTIONS THAT THE OIL WILL CONSTITUTE ABOUT 50% TO 85% OF THIS MIXTURE AND ADDED MICROCRYSTALLINE WAX MELTING IN THE RANGE OF ABOUT 95* F. TO 115* F. IN AN AMOUNT IN THE RANGE OF ABOUT 2 TO 25 WEIGHT PER CENT BASED ON THE TOTAL MIXTURE, BOTH OF SAID MICROCRYSTALLINE WAXS BEING FURTHER CHARACTERIZED BY HAVING BOILING RANGES ABOVE 900* F. ON A TRUE BOILING POINT BASIS.

Claim 3

THE METHOD OF MAKING A PETROLATUM MIXTURE FROM A REDUCED PETROLEUM CRUDE OIL WHICH IS SUBSTANTIALLY FREE FROM ASPHALTS AND RESINS AND FROM WHICH COMPONENTS BOILING UP TO 900* F. AND INCLUDING MOTOR OIL DISTILLATE HAVE BEEN DISTILLED, WHICH METHOD COMPRISES SEPARATING FROM SAID REDUCED CRUDE A PETROLATUM MIXTURE CONSISTING ESSENTIALLY OF MICROCRYSTALLINE WAXES AND OIL, DEOILING SAID MIXTURE TO OBTAIN A SUBSTANTIALLY OIL FREE MICROCRYSTALLINE WAX HAVING A MELTING POINT OF AT LEAST ABOUT 120* F. AND AN OIL CONTAINING MICROCRYSTALLINE WAXES OF LOWER MELTING POINT, SEPARATING FROM LAST NAMED OIL SUBSTANTIALLY OILFREE MICROCYSTALLINE WAX HAVING A MELTING POINT IN THE RANGE OF ABOUT 95 TO 115* F., BLENDING REFINED WHITE MINERAL OIL WITH SAID MICROCYSTALLINE WAX HAVING A MELTING POINT OF AT LEAST 120* F. IN AN AMOUNT TO GIVE A MIXTURE CONTAINING ABOUT 50 TO 90 WEIGHT PER CENT WHITE MINERAL OIL BASED ON THESE TWO COMPONENTS AND ADDING TO THESE TWO COMPONENTS SAID MICROCRYSTALLINE WAX HAVING A MELTING POINT IN THE RANGE OF 95 TO 115* F. IN AN AMOUNT IN THE RANGE OF 2 TO 25 WEIGT PER CENT BASED ON THE TOTAL MIXTURE.

Claim 4

THE METHOD OF MAKING A PETROLATUM MIXTURE FROM A REDUCED PETROLEUM CRUDE OIL WHICH IS SUBSTANTIALLY FREE FROM ASPHALTS AND RESINS AND FROM WHICH COMPONENTS BOILING UP TO 900* F. AND INCLUDING MOTOR OIL DISTILLATE HAVE BEEN DISTILLED, WHICH METHOD COMPRISES SEPARATING FROM SAID REDUCED CRUDE A PETROLATUM MIXTURE CONSISTING ESSENTIALLY OF MICROCRYSTALLINE WAXES AND OIL, DEOILING SAID MIXTURE TO OBTAIN A SUBSTANTIALLY OIL FREE MICROCRYSTALLINE WAX HAVING A MELTING POINT OF AT LEAST ABOUT 120* F. AND AN OIL CONTAINING MICROCRYSTALLINE WAXES OF LOWER MELTING POINT, SEPARATING FROM LAST NAMED OIL SUBSTANTIALLY OILFREE MICROCYSTALLINE WAX HAVING A MELTING POINT IN THE RANGE OF ABOUT 95 TO 115* F., BLENDING REFINED WHITE MINERAL OIL WITH SAID MICROCYSTALLINE WAX HAVING A MELTING POINT OF AT LEAST 120* F. IN AN AMOUNT TO GIVE A MIXTURE CONTAINING ABOUT 50 TO 90 WEIGHT PER CENT WHITE MINERAL OIL BASED ON THESE TWO COMPONENTS AND ADDING TO THESE TWO COMPONENTS SAID MICROCRYSTALLINE WAX HAVING A MELTING POINT IN THE RANGE OF 95 TO 115* F. IN AN AMOUNT IN THE RANGE OF 2 TO 25 WEIGT PER CENT BASED ON THE TOTAL MIXTURE.
