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.

Use

Stearyl palmityl tartrate is used as emulsifier under the E number E 483. The Food and Agriculture Organization of the United Nations sets limits of use at 4 g/kg for bakery wares and 5 g/kg for dessert products.^[2]

Use of stearyl palmityl tartrate is prohibited in Australia.^{[citation needed]}
