PEG-75 Lanolin (PEG-75 Lanolin) is a versatile cosmetic ingredient renowned for its dual functionality as both an emollient and an emulsifier. Derived from a biobased source—specifically, a natural secretion from the sebaceous glands of sheep—this unique compound is rich in complex esters and polyesters that include a diverse blend of nearly seventy alcohols and fatty acids. Its emollient properties help to soften and soothe the skin, enhancing hydration while providing a protective barrier. As an emulsifier, PEG-75 Lanolin stabilizes formulations, ensuring that oil and water components blend seamlessly for a smooth and luxurious application experience.
