Petroleum jelly ointment on his injuries and showing his past injuries healed, he claimed, by his miracle product. He opened his first factory in 1870 in Brooklyn using the name Vaseline. Petroleum jelly is a mixture of hydrocarbons, having a melting point usually close to human body temperature, approximately . It is flammable only when heated to liquid; then the fumes will light, not the liquid itself, so a wick material like leaves, bark, or small twigs is needed to ignite petroleum jelly. It is colorless or has a pale yellow color (when not highly distilled), translucent, and devoid of taste and
Wharton's jelly Wharton's jelly Wharton's jelly ("substantia gelatinea funiculi umbilicalis") is a gelatinous substance within the umbilical cord also present in vitreous humor of the eyeball, largely made up of mucopolysaccharides (hyaluronic acid and chondroitin sulfate). It also contains some fibroblasts and macrophages. It is derived from extra-embryonic mesoderm. As a mucous tissue, it protects and insulates umbilical blood vessels. Wharton's jelly, when exposed to temperature changes, collapses structures within the umbilical cord and thus provides a physiological clamping of the cord (an average of) 5 minutes after birth. Cells in Wharton's jelly express several stem cell genes, including telomerase. They can
