history
Vaseline was originally a by-product extracted from petroleum by the inventor Robert A. Chezbroth in 1859. Its original name was "petroleum gum" (refined paraffin), in which "petroleum" was petroleum and "jelly" was a gelatinous substance, and was later named vaseline.
And in the American patent of the product, it is written: "I, Robert A. Chezebro, have invented a brand-new and very useful petrochemical product called vaseline."
This word comes from the combination of the German word "wasser" and the Greek word "elaeon".
