What it is
Polyoxyethylene sorbitan monostearate is a synthetic emulsifier made from sorbitan (a derivative of sorbitol, a sugar alcohol) and stearic acid (a fatty acid). It is produced by reacting these components with ethylene oxide. It is a viscous, oily liquid that is soluble in water.
Why it's used
This ingredient is added to foods to help mix ingredients that normally don't blend well, such as oil and water. It is often found in ice cream, baked goods, and dessert toppings to improve texture and prevent separation.
Health notes
In the United States, polyoxyethylene sorbitan monostearate is generally recognized as safe (GRAS) by the FDA for use as an emulsifier. International bodies like JECFA and EFSA have also evaluated it. Studies on the health effects of consuming this ingredient at typical levels found in food have not shown significant concerns.
