Sorbitan monostearate

Sorbitan monostearate is a non-ionic surfactant and emulsifier. It is produced by the esterification of sorbitol (a sugar alcohol) with stearic acid, which is a fatty acid commonly derived from vegetable or animal fats.

Manufacturers use sorbitan monostearate as an emulsifier to help blend oil and water-based ingredients, preventing separation and improving texture. It is often found in baked goods like biscuits and cakes, as well as in confectionery and ice cream.

Sorbitan monostearate is an authorised food additive in Great Britain, listed on the Register of Food Additive Authorisations. The European Food Safety Authority (EFSA) has evaluated sorbitan monostearate and other sorbitan esters, establishing an acceptable daily intake (ADI) for the group. At typical consumption levels, it is not associated with adverse health effects.
