- STEOL CS-330 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.
- STEOL CS-330 is not only milder than sodium lauryl, 1 mole or 2 mole laureth sulfates but also exhibits greater salt tolerance and solubilizing properties. Its low irritation properties make it useful for mild cleansing products, as well as baby products.
- STEOL CS-330 offers excellent skin compatibility, along with good foam and viscosity characteristics, all important considerations in shampoo, hand soap, and bath product formulations. STEOL CS-330 based products can be readily thickened with salts, betaines, and amides, with the latter two also offering foam enrichment. By modifying the additive levels, formulas exhibiting a variety of performance and physical attributes can be developed. Since STEOL CS-330 is compatible with commonly used opacifiers and pearlizing agents, the formulator is afforded flexibility in developing the desired product appearance.

Packaging & Availability
Storage & Handling
- Storage & Handling
- Normal safety precautions (i.e., gloves and safety goggles) should be employed when handling STEOL CS-330. Contact with the eyes and prolonged contact with the skin should be avoided. Wash thoroughly after handling material.
- It is recommended that STEOL CS-330 be stored in sealed containers and kept at temperatures above 45°F (7°C). Avoid overheating or freezing. If material is 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).
