Vaseline source:
/kloc-in the 9th century, an oil driller in a new oil field in Pennsylvania, USA, found that the wax scale on the sucker rod had a certain analgesic effect on burns and cuts.
1859, pharmacist and chemist Robert Chesenberg visited Brooklyn, new york. After he heard about it, he collected some wax scales and took them back to study. Robert Chesenberg spent 1 1 year refining these petroleum residues to make a petroleum-based ointment that will not deteriorate.
This by-product is also called vaseline, in which "petroleum" is petroleum and "jelly" refers to gelatinous substances. The commercial vaseline produced by these two companies is called vaseline and rotine Raton respectively.
Robert Chesenberg named it Vaseline, and applied for American patent in 1870. The name may come from the combination of the German word "wasser" and the Greek word "elaeon".
