- Applications
- STEPAN MWA-181 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-181 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.

STEPAN MWA-181 is available in drums.
Storage & Handling
- Storage & Handling
- It is recommended that STEPAN MWA-181 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 (i.e., gloves and safety goggles) should be employed when handing STEPAN MWA-181. Contact with eyes, nose or prolonged contact with skin should be avoided. Wash thoroughly after handling STEPAN MWA-181. See the SDS for further information.
- Non-Bulk Storage Information: It is recommended that STEPAN MWA-181 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 electrically grounded fittings are recommended. Material should be stored between 26-32°C (80-90°F). Pumps, pipes and transfer lines should be 316 stainless steel.
- Workplace Exposure
Occupational exposure can occur primarily through skin contact or via inhalation of vapors and mists. Engineering controls, personal protective equipment, and other workplace practices should be used to control these exposures. See the SDS for further information.
