White soft paraffin and yellow soft paraffin are mixtures of semi-solid hydrocarbons. They are used as bases for ointments, as emollients in skin diseases, and as lubricants in treating dry eyes. Soft paraffin is also known as petroleum jelly, petrolatum, and Vaseline.

Specialized over-the-counter ointment treatments for calluses and feet with dry, cracked skin may include (instead of salicylic acid) an endoprotease in a white petroleum jelly vehicle base. Known to improve the softness and density of the callus, the endoprotease breaks the ten end peptide bonds on the protein chains of callus tissue, leaving the normal skin unaffected (as normal skin does not contain this type of long-chain protein). Once treated, a gentle rubbing action with a wet washcloth is sufficient to gradually exfoliate callus tissue. 

Petrolatum is usually a soft product containing approximately 20% oil and melting between 38°C (100°F) and 60°C (140°F). Petrolatum or petroleum jelly is essentially a mixture of microcrystalline wax and oil. It is produced as an intermediate product in the refining of microcrystaUine wax or compounded by blending appropriate waxy products and oils. Petrolatum colors range from the almost black crude form to the highly refined yellow and white pharmaceutical grades. 

Petroleum jelly a translucent, yellowish to amber or white, hydrocarbon substance (m.p. 38-54°C) having almost no odor or taste derived from petroleum and used principally in medicine and pharmacy as a protective dressing and as a substitute for fats in ointments and cosmetics also used in many types of polishes and in lubricating greases, rust preventives, and modeling clay obtained by dewaxing heavy lubricating-oil stocks. 

In its strictest definitive form, an ointment is classified as any semi-solid containing fatty material and intended for external application (U.S. Pharmocopeia, USP). In this discussion, ointments will be defined as semisolid anhydrous external preparations. In the nineteenth century, ointments were based on lard, a compounding material, the usefulness of which was severely limited by its tendency to turn rancid. Early in the twentieth century, lard was replaced by petrolatum (white or yellow soft paraffin or petroleum jelly). In present practice, nonmedicated ointments (ointment bases) are used alone, for emollient or lubricating purposes, or in combination with a drug for therapeutic purposes.

In the preparation of an oil mull, the sample is ground in the same way as described previously, and a small quantity of an oil, usually a white mineral oil (such as a medicinal white oil), is added and mixed with the sample to form a stiff paste—to a consistency of petroleum jelly. The paste is distributed between a pair of infrared windows (usually KBr or NaCl) to form a thin translucent film. If the film appears to be totally opaque, then...
