Science
Mechanism of Action
This ingredient operates as an effective emollient, imparting softness and smoothness to the skin's surface. As a surfactant and emulsifier, it plays a critical role in stabilizing diverse oil and water phases, forming finely dispersed emulsions. Its polypropylene glycol structure also grants it versatility as a solubilizer and solvent, impacting a broad range of formulation properties like viscosity.

Safety Profile
The Cosmetic Ingredient Review (CIR) Expert Panel assessed polyether lanolins, including PPG-10 Lanolin Alcohol Ether, concluding they are 'safe as used' in cosmetic formulations, specifically when engineered to be non-irritating. Reported usage concentrations range from 0.001% to 15%. It is crucial to note that Lanolin and Lanolin Alcohol, the parent compounds, have been associated with allergenicity in patch tests, and Lanolin was designated Contact Allergen of the Year by the American Contact Dermatitis Society. This history suggests a need for careful formulation, particularly for sensitive individuals.
