A white or colorless pertroleum-derived solid wax It is often used in making candles and cosmetics This is the wax commonly found in the grocery store and used to seal canning jars
hydrocarbon identified by saturated straight (normal or branched {iso}) carbon chains The generalized paraffinic molecule can be symbolized by the formula CH+ Paraffins are relatively non-reactive and have excellent oxidation stability In contrast to naphthenic oils, paraffinic lube oils have relatively high wax content and pour point, and generally have a high viscosity index (VI) Paraffinic solvents are generally lower in solvency than naphthenic or aromatic solvents See hydrocarbon, normal paraffin, and saturated hydrocarbon

Petroleum jelly, vaseline, petrolatum or soft paraffin is a semi-solid mixture of hydrocarbons (with carbon numbers mainly higher than 25), originally promoted as a topical ointment for its healing properties. Its folkloric medicinal value as a "cure-all" has since been limited by better scientific understanding of appropriate and inappropriate uses However, it is recognized by the U.S. Food and Drug Administration (FDA) as an approved Over-The-Counter (OTC) skin protectant and remains widely used in cosmetic skin care.
