POLYSTEP B-330S is a sodium lauryl ether sulfate derived from fatty alcohols, ethoxylated to an average of 3 moles, and sulfated via Stepan's continuous SO3 process. POLYSTEP B-330S is used in latex manufacture; it aids in the control of latex particle size. It is useful in most polymer systems, especially with vinyl chloride and styrene butadiene emulsions.

Safety & Health
- Toxicity
POLYSTEP B-330S is practically non-toxic orally (LD50 is >5 g/kg) and causes mild to moderate skin and moderate eye irritation at 10% active.
Packaging & Availability
- Standard Packaging
POLYSTEP B-330S is available in bulk and 55 gallon drums (net weight 450 lb/204 kg).
Storage & Handling
- Storage & Handling
Normal safety precautions (i.e. gloves and safety goggles) should be employed when handling POLYSTEP B-330S. Contact with the eyes and prolonged contact with the skin should be avoided. It is recommended that POLYSTEP B-330S be stored in sealed containers at temperatures above 45°F (7°C). Avoid overheating or freezing. If material has been frozen, mild heat and agitation are recommended to ensure the material is homogeneous before use.
Bulk Storage Information
Tanks made of 316 stainless steel or fiberglass with an Atlac 382 corrosion liner are recommended. Positive displacement gear pumps and piping should be 316 stainless steel. Recommended storage for bulk tanks is 90-100 °F (32-38 °C).
