Namely
PEG-150 distearate is a surfactant with a strong HLB (18.9). It mainly makes it possible to create oil-in-water emulsions and acts as a thickener.
Its functions (INCI)
Emulsifying : Promotes the formation of intimate mixtures between immiscible liquids by modifying the interfacial tension (water and oil)
Surfactant : Reduces the surface tension of cosmetics and contributes to the even distribution of the product when it is used
Viscosity controlling : Increases or decreases the viscosity of cosmetics
