Is sorbitan monostearate safe?
Yes—E491 is an approved food emulsifier; EFSA set a group ADI of 10 mg/kg body weight per day (expressed as sorbitan) for sorbitan esters, and it’s considered safe at permitted use levels.
Is sorbitan monostearate vegan?
Not always—the stearic acid can be sourced from either vegetable oils or animal fat, so vegan status depends on the supplier; check with the manufacturer for plant-derived sources.
What is sorbitan monostearate made from?
It’s an ester of sorbitan (from dehydrated sorbitol) and stearic acid, which can come from vegetable oils (e.g., palm/soy) or animal fat (tallow).
E491 what is it made from?
E491 is produced by reacting sorbitan (derived from sorbitol) with stearic acid; the stearic acid may be plant- or animal-derived.
How is sorbitan monostearate and sorbitan tristearate different?
Sorbitan monostearate (E491) has one stearic acid group, while sorbitan tristearate (E492) has three. The tri-ester is more lipophilic (lower HLB) and is used for stronger water-in-oil emulsification and fat crystal control compared with the mono-ester.
