Acetylated lanolin

Acetylated lanolin (CAS 91053-41-7) is a modified wool wax derivative produced by acetylating natural lanolin to reduce tackiness and improve compatibility with formulation bases.

Where is Acetylated lanolin used?

• Personal care: emollient and humectant in lip balms, skin creams and hair conditioners
• Coatings and industrial lubricants: rheology modifier for viscosity adjustment
• Adhesives and sealants: flexibility and substrate wetting
• Water-in-oil formulations: emulsifier for stability
• It improves film-forming characteristics on metal and substrate surfaces.

Good to know: Unlike standard lanolin, it delivers moisturizing and emulsification performance with a lighter, less greasy skin feel. It is often preferred where conventional lanolin would introduce unwanted stickiness.

Commercial specifications

• Cosmetic-grade material conforming to standard purity specifications is the most common commercial form.
• Typically packaged in drums or pails for bulk industrial use.
