Lansurf AE73

Lansurf AE73 is a biodegradable nonionic surfactant obtained by ethoxylating cetyl oleyl alcohol. It offers excellent compatibility with soaps, anionic, cationic, and other nonionic surfactants, providing broad formulation flexibility.

Lansurf AE73 delivers strong oil/water emulsification performance, making it highly effective in systems containing vegetable oils, mineral oils, waxes, and alkyd resins.

​​

Key Features

​

• Highly effective emulsifier for vegetable oils, mineral oils, paraffin waxes, and alkyd resins.

• Excellent Oil/Water emulsion stability when used alone or in combination with co‑emulsifiers. 

• Good wetting and dispersing properties for enhanced formulation performance.

• Versatile nonionic surfactant compatible with anionic, cationic, and nonionic systems.

• Provides reliable performance across metalworking, agrochemicals, oilfield, textile, and coating applications.

• Readily biodegradable, supporting environmentally responsible formulations.
