Is sorbitan tristearate harmful?
In 2017 EFSA set a group ADI of 10 mg/kg body weight per day, expressed as sorbitan, for the sorbitan esters E 491–495. In the 2025 update with newer consumption data, the group ADI was exceeded in toddlers and children at the 95th percentile (refined non-brand-loyal scenario) in a limited number of surveys. EFSA concluded that conservative assumptions clearly overestimated exposure, so the exceedance is not of safety concern.
Is E492 permitted in Vietnam?
Yes. INS 492 (sorbitan tristearate) is listed in Appendix 1 of Circular 24/2019/TT-BYT, the list of additives permitted in food.
Can children and pregnant women have E492?
In 2025, updating the exposure to sorbitan esters (E 491–495) with newer consumption surveys, EFSA found that the group ADI of 10 mg sorbitan/kg body weight per day was exceeded in toddlers and children at the 95th percentile (refined non-brand-loyal scenario) in a limited number of surveys. EFSA concluded that conservative assumptions clearly overestimated the exposure, so the exceedance is not of safety concern. The source says nothing specific about pregnant women. If you have a particular health condition, ask a doctor.
