Sorbitan monopalmitate
A synthetic emulsifier made from sorbitol and palmitic acid, used to blend fats and water smoothly in confectionery and baked goods.
What is it?
Sorbitan monopalmitate is an ester formed by combining sorbitol (a sugar alcohol) with palmitic acid (a common saturated fatty acid found in palm oil and many foods). It belongs to the sorbitan ester family (E491-E495), a group of closely related synthetic emulsifiers widely used in food manufacturing.
What does it do?
Acts as an emulsifier: it has one water-attracting end and one fat-attracting end, allowing it to sit at the interface between oil and water, stabilising mixtures that would otherwise separate. In chocolate and confectionery coatings it improves gloss and reduces viscosity; in baked goods it helps distribute fats evenly through a batter for a more uniform crumb texture.
Where you will see it
Most commonly found in chocolate and cocoa products, sugar confectionery, decorations and coatings, fine bakery products, instant drink powders, desserts, and jelly marmalades. On a UK ingredient label it appears as 'sorbitan monopalmitate' or 'E495'.
What the science says
EFSA 2017 re-evaluation: group ADI revised downward
The European Food Safety Authority re-evaluated the whole sorbitan ester group (E491-E495) in 2017 and set a group acceptable daily intake of 10 mg per kg body weight per day, expressed as sorbitan. This replaced an earlier 1974 Scientific Committee for Food figure of 25 mg/kg bw/day for E495. The revision was a methodological update based on a long-term mouse study, not a new toxicity finding. At typical food intakes the group ADI is not expected to be exceeded.
The EFSA ANS Panel established a group ADI of 10 mg sorbitan/kg body weight per day for E491-E495, based on a NOAEL of 2,600 mg/kg bw/day in a long-term mouse toxicity study and an uncertainty factor of 100.
The previous 1974 SCF allocation of 25 mg/kg bw/day for E495 was replaced by the lower group ADI of 10 mg/kg bw/day; this reflects a more cautious calculation approach, not evidence of harm at former intakes.
Genotoxicity: no concern identified
The EFSA panel concluded that the sorbitan ester group does not raise concern for genotoxicity. Long-term studies in both mice and rats showed no indication of carcinogenicity. Specific toxicology data for E495 are limited and the safety conclusion relies on read-across from sorbitan monostearate (E491), the best-studied member of the group.
Sorbitan esters (E491-E495) did not raise concern with respect to genotoxicity; long-term studies in mice and rats showed no carcinogenicity signal. Specific data for E495 are limited; the conclusion relies on read-across from E491.
Metabolism: broken down to components the body handles routinely
In the gut, sorbitan esters are hydrolysed to their component parts: sorbitol and fatty acids. Both are normal metabolic substrates. Palmitic acid is a saturated fat present naturally in many foods; sorbitol is a naturally occurring sugar alcohol. There is no accumulation in tissues and no novel metabolic product of concern identified in studies.
Sorbitan esters are hydrolysed in the gastrointestinal tract to sorbitol and fatty acids, which are normal food components handled by standard metabolic pathways.
Where it stands with the regulators
Who should be careful
No specific group is required to avoid E495 under UK food law. People with known allergies to palm-derived ingredients may wish to check ingredient lists for 'sorbitan monopalmitate' or 'E495', as it is derived from palmitic acid (typically of palm origin), though palm oil itself is not a declarable allergen under UK law.
The honest read
Sorbitan monopalmitate is one of five closely related sorbitan esters used in food since the mid-twentieth century. The science base is thinner for E495 specifically than for the more-studied E491, and EFSA's 2017 review noted the data gap, though it considered read-across justified. The group ADI was revised down from the 1974 figure, but at typical food exposure levels the available evidence does not point to a harm pathway. This is an ordinary manufacturing emulsifier whose main open question is data adequacy rather than a known toxicological signal.

Common questions
Is E495 banned in the UK?
No. Sorbitan monopalmitate (E495) is approved for use in the UK under the assimilated EU Regulation 1333/2008 as retained in Great Britain law.
Was E495's safety ever questioned by regulators?
In its 2017 re-evaluation, EFSA noted that direct toxicology data for E495 are limited and that the safety conclusion relies on read-across from sorbitan monostearate (E491). The group ADI was also revised downward from the 1974 figure. EFSA considered the evidence sufficient, but the data gap is a real one.
What foods contain E495?
Chocolate and cocoa products, sugar confectionery, cake glazes and coatings, fine baked goods, instant drink powders, and desserts. Check for 'sorbitan monopalmitate' or 'E495' on the label.
Is E495 vegan?
It depends on the manufacturing source. E495 is made from sorbitol and palmitic acid; palmitic acid is most commonly derived from palm oil (plant-based) but can in principle come from animal fat. Most commercial production uses vegetable-source palmitic acid, but this is not guaranteed unless the manufacturer confirms it. Strict vegans should verify with the brand.
