Science
Mechanism of Action
This ingredient functions by decreasing the surface tension of disparate substances, facilitating the formation and stabilization of emulsions. On the skin's surface, it acts as a lubricant, promoting a smooth feel. As a lanolin derivative, it provides occlusive emollience, forming a protective film on the stratum corneum that reduces transepidermal water loss (TEWL) and thus softens the skin. Its polyethylene glycol (PEG) modification significantly increases its solubility in water and alcohol compared to traditional lanolin, expanding its utility in diverse formulations. Furthermore, it can solubilize hydrophobic compounds in aqueous systems and serve as a general surfactant.

Safety
Safety Profile
The Cosmetic Ingredient Review (CIR) Expert Panel deemed PEG-60 Lanolin safe for use in cosmetics. Typical concentrations range from 0.05%-2% in leave-on products and 0.05%-1% in rinse-off products. While the FDA generally does not pre-approve cosmetic ingredients, a known concern is the potential for 1,4-dioxane by-product, which can be mitigated through stringent purification.
