Emulsifier
Emulgators are used in cosmetics for example in creams and bath oils. A cream consists largely of an emulsion of fat in water or of water in fat, while a bath oil often contains an emulsifier to partially distribute the oil in the water. Without an emulsifier, the oil would float on the water. Examples of emulsifiers used in cosmetic products are glyceryl monostearate, Polysorbate 20, accasia, tragacanth agar, and pectin.
