Stearyl palmityl tartrate is a derivative of tartaric acid used as an emulsifier. It is produced by esterification of tartaric acid with commercial grade stearyl alcohol, which generally consists of a mixture of the fatty alcohols stearyl and palmityl alcohol.[1] Stearyl palmityl tartrate consists mainly of diesters, with minor amounts of monoester and of unchanged starting materials.
