Lanolin Alcohol 400 (Eucerin 400) is a high-purity, hydrophilic derivative of lanolin, widely used in pharmaceuticals, cosmetics, and topical formulations as a potent emulsifying and moisturizing agent. It has enhanced emulsifying properties compared to Lanolin Alcohol 200 and is particularly effective in stabilizing complex oil-in-water emulsions.
🏭⚗️ Production
Lanolin Alcohol 400 is obtained through saponification of purified lanolin, followed by fractionation and purification to isolate the higher molecular weight alcohol fraction. This process ensures a high content of sterols and long-chain alcohols, which provide superior emulsifying capacity and emulsion stability. The product is standardized for pharmaceutical and cosmetic applications.
🔬 Properties
Lanolin Alcohol 400 appears as a pale yellow, waxy solid with a mild characteristic odor. It is soluble in alcohol, oils, and chloroform, and partially soluble in water. As a non-ionic emulsifier, it stabilizes oil-in-water emulsions efficiently and improves the texture, spreadability, and moisture retention of topical formulations. Its amphiphilic structure allows interaction with both hydrophilic and lipophilic ingredients.
🧪 Applications
Lanolin Alcohol 400 is used in pharmaceutical creams, ointments, and lotions to enhance emulsification, skin conditioning, and hydration. In cosmetics, it stabilizes complex emulsions in moisturizers, sunscreens, and lip care products. It improves product consistency, skin feel, and water-binding capacity, making it suitable for high-quality dermatological and personal care formulations.
⚠️ Safety
Lanolin Alcohol 400 is generally considered safe for topical use. Rare allergic reactions may occur in individuals sensitive to lanolin derivatives. It should be stored in a cool, dry place, protected from light and moisture. Handling in industrial settings should involve gloves to avoid prolonged skin contact, although it is not hazardous under normal conditions.
