Robert Chesebrough Vaseline. In 1875, he founded the Chesebrough Manufacturing Company that in 1955 became Chesebrough-Ponds, a leading manufacturer of personal-care products. Chesebrough patented the process of making petroleum jelly (U.S. Patent 127,568) in 1872. By 1874, stores were selling over 1400 jars of Vaseline a day. Chesebrough's success stemmed from firm belief in his product. Before he began selling petroleum jelly, he tested it on his own cuts and burns. Chesebrough was still unable to sell any to drug stores until he travelled around New York demonstrating his miracle product. In front of an audience, he would burn his skin with
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
