Polysorbate 20

Polysorbate 20 is a non-ionic surfactant and emulsifier derived from sorbitol and lauric acid. It helps to mix oil and water-based ingredients in cosmetic formulations, creating stable products. It can also act as a solubilizer for fragrances and essential oils, allowing them to disperse evenly in water-based solutions.
