Polysorbate 80

In skin care products, polysorbate 80, also known as Tween 80, is considered a safe and non-toxic chemical .  The ingredients in polysorbate 80 work together to form a powerful emulsifier, which means they help liquids of varying densities bind together and avoid separation.  
Additionally, polysorbate 80 is a solubiliser, which means it helps dissolve ingredients that would otherwise be difficult or impossible to dissolve on their own. It is also a surfactant which is a material that lowers the surface tension of a liquid that makes it easier and smoother to spread. Because of these characteristics, polysorbate 80 is used for a variety of cosmetics and personal care products.  
Polysorbate 80 specifically is a common fragrance and essential oil solubiliser as well as an emulsifying agent. Soluble in alcohol and water but not in oil, Polysorbate 80 is characteristically a co-emulsifier that is used to modify the viscosity (i.e. thickness) of a product.It is generally used to combine thicker or heavier oils  such as sunflower oil, argan oil and other thick carrier oils. It is usually added to cosmetic formulations during the oil process which can help to achieve a uniform consistency by allowing different ingredients to mix more thoroughly. It helps creams, lotions, and gels remain stable, particularly those made with cold processes. Polysorbate 80 can be added to a variety of sprays as a fragrance and essential oil dispersal agent. Bath oils, for example, can be made by mixing Polysorbate 80 with an appropriate liquid. Bath bombs, sugar or salt scrubs, and whipping or foaming body creams are all examples of items that contain it.  
Polysorbate is also known for its soothing feeling when it is applied to the skin, making it an excellent cosmetic ingredient for skincare products of all styles and conditions.
