Article

PEG-75 is a type of polyethylene glycol. PEGs are amazingly versatile skin care ingredients in skin care because of their many uses and broad compatibility with different types of ingredients. PEG-75 can be used as a humectant (water-binding agent) to boost skin’s hydration. It can also be used as a solvent that improves the overall texture of a formula by making the ingredients mesh more cohesively. 

With any PEG ingredient followed by a number, the higher the number, the higher molecular weight of the ingredient. Thus, PEG-75 will feel more substantial on skin than, say, PEG-14. 

PEG-75 has many derivatives, including PEG-75 lanolin oil, PEG-75 stearate, PEG-75 shea butter glycerides, and PEG-75 propylene glycol stearate. Each offers its own distinct functions and properties.  

PEG-75 has been deemed a safe cosmetic ingredient by the Cosmetic Ingredient Review Expert Panel. Their report looked at concentrations between 0.2-36%.
