Consumer Advice
Polysorbate 20 is a synthetic emulsifier made from sorbitol, fatty acids and ethylene oxide. It helps oil and water mix evenly and is used in drinks, sauces and baked goods. It contains no animal ingredients and is generally recognized as safe at normal levels; as with the broader emulsifier family, very large intakes may cause mild discomfort in some sensitive individuals.
