It is a water-soluble derivative of lanolin, with PEG-27 indicating the molecular weight of the polyethylene glycol (PEG) used in the compound. PEG-27 Lanolin is widely used in the cosmetics and pharmaceutical industries due to its emollient, moisturizing, and occlusive properties, which help to retain skin moisture and protect it from external irritants. It is also known for its ability to improve skin hydration, reduce dryness, and promote a smooth, soft texture. The compound is generally considered safe for use in personal care products, although individuals with sensitive skin or allergies to lanolin may experience adverse reactions.
