- STEPAN MWA-180 is a biodegradable linear fatty alcohol ether sulfate. Stepan's continuous SO₃ process minimizes salt and free alcohol content, eliminates the presence of chlorides, permitting more consistent control of viscosity. It is a clear liquid of exceptionally light color and good odor. STEPAN MWA-180 is not recommended in alkaline systems since ammonia is liberated above pH 7.
- STEPAN MWA-180 is used in the emulsification of components and can enable improved performance in metal cleaning in metalworking applications. It can be used to efficiently remove oil residue from metal surfaces.

Storage & Handling
- Storage & Handling
- It is recommended that STEPAN MWA-180 be stored in sealed containers kept in a well-ventilated area away from sparks, fire, and open flame. Avoid overheating or freezing. Equipment should be grounded when transferring or using material. Normal safety precautions (e.g., gloves and safety goggles) should be employed when handing STEPAN MWA-180. Contact with eyes, nose or prolonged contact with skin should be avoided. Wash thoroughly after handling STEPAN MWA-180. See the SDS for further information.
- Non-Bulk Storage Information: It is recommended that STEPAN MWA-180 be stored in sealed containers and kept in a well ventilated, cool, dry area away from sparks, fire, and open flame. Avoid overheating or freezing. Equipment should be grounded when transferring or using material.
- Bulk Storage Information: Tanks made of 316 stainless steel or fiberglass with an Atlac 382 corrosion liner, atmospheric storage with a flame arrestor, and fittings electrically grounded are recommended. Centrifugal pumps and piping should be 316 stainless steel. Recommended storage for bulk tanks is 80-90°F (26-32°C).
