Petroleum jelly or petrolatum is made by refining a by product of oil drilling.Vaseline is a well-known brand of petroleum jelly originally produced by Chesebrough-Ponds, which was purchased by Unilever in 1987.
Vaseline has become a genericized trademark meaning petroleum jelly.The raw material for petroleum jelly was discovered in 1859 in Titusville, Pennsylvania where it was sticking to some of the first oil rigs in the U.S. The riggers hated the paraffin-like material because it caused the rigs to seize up, but they used it on cuts and burns because it hastened healing.
Petrolatum is a semi-solid mixture of hydrocarbons, having a melting-point usually ranging from a little below to a few degrees above 100° F (37° C). It is colorless, or of a pale yellow color, translucent, and devoid of taste and smell. It does not oxidize on exposure to the air, and is not readily acted on by chemical reagents.
It is insoluble in water. It is soluble in chloroform, benzene, carbon disulphide and oil of turpentine. It also dissolves in warm ether and in hot alcohol, but separates from the latter in flakes on cooling.uses.The finest grade of petroleum jelly is also adapted for use as a pomade for the hair. It is also used for treating chapped hands or lips, toenail fungus, and nosebleeds.
Because the oil protects skin from the atmosphere and air-borne bacteria it may shorten healing time.
Also from this morning's reading:
“A man was going down from Jerusalem to Jericho when he fell into the hands of bandits. They stripped him, beat him, and went away, leaving him half dead. By chance, a priest was traveling along that road. When he saw the man, he went by on the other side. Similarly, a Levite came to that place. When he saw the man, he also went by on the other side. But as he was traveling along, a Samaritan came across the man. When the Samaritan saw him, he was moved with compassion. He went to him and bandaged his wounds, pouring oil and wine on them.
Then he put him on his own animal, brought him to an inn, and took care of him. The next day he took out two denarii and gave them to the innkeeper, saying, ‘Take good care of him. If you spend more than that, I'll repay you when I come back.’
