What is it?

Ethanolamine (C2H7NO) is used in the pharmaceutical industry as a pH adjuster and buffering agent. It is a colorless to yellow clear liquid. There is evidence that it can be a human skin toxicant or allergen, and it should not be left on the skin. It has certain restrictions for use in the cosmetics industry. Ethanolamine oleate, a prescription drug, is a sclerosing agent. It works by creating scar tissue inside a swollen or dilated (wider than normal) vein to prevent bleeding.[1]
