Polysorbate 20 is the essential ingredient for making body and room sprays. It acts as a solubiliser, allowing the oil phase of your formula to disperse and fully incorporate into the water phase. Polysorbate 20 is a solubilizer commonly used to bind fragrance and essential oils with water based products.
Polysorbate 80 is a common fragrance and essential oil solublizer as well as an emulsifying agent. It is soluble in water and alcohol and insoluble in oils. It is typically a co-emulsifier that is used both as a viscosity modifier and a dispersing agent for fragrances and essential oils for room sprays and linen sprays. When combined with liquid oils, Polysorbate 80 creates a blooming bath oil. It can also be used in a self-emulsifying sugar or salt scrub. In bath bombs, you can add up to 6% as a wetting agent (rather than a traditional witch hazel or liquid oil) to help prolong fizzing in the tub.
