Lanolin (Wool Wax)

lanolin · wool wax · wool grease

A waxy substance secreted by sheep sebaceous glands used as an occlusive emollient. FDA recognizes it as safe; the CIR affirmed safety in 2005. However, the CIR initiated a re-evaluation in 2023 due to persistent allergenicity concerns. Contact allergy to lanolin, while less common than historically believed, remains a real consideration for sensitive individuals.
