Mineral oil is used as a laxative to alleviate constipation by retaining water in stool and the intestines. [11] Although generally considered safe, as noted above, there is a concern of mist inhalation leading to serious health conditions such as pneumonia. [12] Mineral oil can be administered either orally [13] or rectally. [14]
Petroleum jelly is a mixture of hydrocarbons, with a melting point that depends on the exact proportions. The melting point is typically between 40 and 70 °C (105 and 160 °F). [8] [9] It is flammable only when heated to liquid; then the fumes will light, not the liquid itself, so a wick material is needed to ignite petroleum jelly.

For instance, liquid paraffin (called mineral oil in the US) is a more viscous and highly refined product which is used as a laxative. Paraffin wax is a waxy solid extracted from petroleum. To prevent confusion between kerosene and the much more flammable and volatile gasoline (petrol) , some jurisdictions regulate markings or colourings for ...
Paraffin wax (or petroleum wax) is a soft colorless solid derived from petroleum, coal, or oil shale that consists of a mixture of hydrocarbon molecules containing between 20 and 40 carbon atoms. It is solid at room temperature and begins to melt above approximately 37 °C (99 °F), [ 2 ] and its boiling point is above 370 °C (698 °F). [ 2 ]

Microcrystalline waxes can generally be put into two categories: "laminating" grades and "hardening" grades. The laminating grades typically have a melting point of 140–175 F (60 – 80 °C) and needle penetration of 25 or above. The hardening grades will range from about 175–200 F (80 – 93 °C), and have a needle penetration of 25 or below.
The Gmelin rare earths handbook lists 1522 °C and 1550 °C as two melting points given in the literature, the most recent reference [Handbook on the chemistry and physics of rare earths, vol.12 (1989)] is given with 1529 °C.
