Lanolin Ethoxylated (PEG-75 Lanolin) is a chemically modified lanolin derived from the reaction of natural wool fat (lanolin) with ethylene oxide. It is a smooth, yellow to amber-colored waxy substance with mild odor, widely used in pharmaceutical, cosmetic, and laboratory formulations for its emulsifying, moisturizing, and protective properties.
🏭⚗️ Production
Lanolin Ethoxylated is produced by reacting anhydrous lanolin with controlled amounts of ethylene oxide under regulated conditions. This process generates polymeric chains averaging 75 ethylene oxide units that are covalently linked to lanolin esters. The resulting product is a stable, water-soluble wax with excellent emulsifying and moisture-retaining characteristics suitable for pharmaceutical and laboratory use.
🔬 Properties
Lanolin Ethoxylated exhibits high biocompatibility, chemical inertness, and hypoallergenic behavior. It is smooth, odorless to mildly odorous, water-soluble, and chemically stable. The material functions as a non-irritating emollient, maintaining skin hydration and forming a protective barrier. In laboratory settings, it acts as an inert medium and stabilizer that does not interfere with experimental formulations or analytical procedures.
🧪 Applications
In pharmaceutical and cosmetic formulations, Lanolin Ethoxylated is used as a base for creams, ointments, lotions, and hair care products to provide moisturizing, emollient, and protective effects. It also functions as an emulsifier to stabilize oil-in-water mixtures and enhances the delivery of active ingredients. In laboratory applications, it serves as an inert carrier, solvent, or vehicle in topical drug studies, dermatological experiments, and the preparation of microemulsions for testing or formulation development.
⚠️ Safety
Lanolin Ethoxylated is generally recognized as safe for topical use and is non-toxic, non-irritating, and hypoallergenic in recommended concentrations. Although rare allergic reactions may occur in individuals sensitive to lanolin, standard handling procedures, including proper storage and hygiene, should be followed to ensure safety during pharmaceutical or laboratory use.
