Polysorbate 80 is an emulsifier that can also be found in moisturizers, makeup and shampoo. It helps bind ingredients together and keep a formula from separating. In fragranced products, it also helps ensure even distribution of the fragrance. Adding emulsifiers helps ensure that our products provide the same performance use after use. The food-grade version of Polysorbate 80 is one of the most common emulsifiers used in ice cream.
