Safety in brief
Safe in moderation
Recorded EatMatrix rating, not a new clinical review. The amount, your sensitivities and country rules still matter.
- Watch for
- No allergen or sensitivity is recorded for this ingredient here. Check the whole product label; this is not an allergen-free guarantee.
- Our advice
- Read the whole food label and consider how often you eat the product. A name or E number does not tell you the amount, and an ingredient rating cannot assess the entire food.
What it is
Polysorbate 65 (Tween 65) is a synthetic emulsifier made from stearic acid and sorbitan with a higher degree of esterification than polysorbates 60 and 80, used mainly in food, cosmetic, and pharmaceutical formulations to stabilize emulsions and improve texture. It appears in some baked goods, confections, and topical products. It is approved for food use within regulated limits by the FDA and EFSA.

Research & body effects
Health notes from our ingredient record
- Generally recognized as safe at typical food-use levels.
- As with related polysorbates, animal research suggests possible effects on gut bacteria with high, regular intake; human evidence at dietary doses is limited.
- Stearic acid component may be derived from animal or plant sources depending on the manufacturer.
