1 of 54 products in this brand
STEOL® CS-270 C is a high-active, concentrated paste at 70% activity level. This 2-mole sodium laureth sulfate functions effectively across various applications, including detergents, dishwashers, laundry products, shampoos, bath products, liquid hand soaps, and industrial cleaners. Its robust foaming capacity remains consistent irrespective of water hardness, and its low skin irritation properties are noteworthy. Furthermore, it is suitable as an additive and scouring agent in textile and agricultural applications.

Applications
  • STEOL CS-270 C provides improved mildness over sodium lauryl sulfate without sacrificing critical performance attributes, such as foaming and viscosity response. Its low irritation properties make it ideal for mild cleansing products.
  • STEOL CS-270 C can be readily formulated into shampoos, bath products, hand soaps, and detergents offering the required physical properties and performance attributes.
  • Products based on STEOL CS-270 C can be thickened with salts, betaines, or amides, with the latter two also serving to enrich the foam. A variety of performance and physical attributes can be obtained simply by adjusting the amount of additive incorporated into a formula. Since STEOL CS-270 C is compatible with commonly used opacifying and pearlizing agents, the formulator is afforded flexibility in developing the desired product appearance.

Packaging & Availability

Packaging Type
Standard Packaging

STEOL CS-270 C is available in bulk and 55 gallon drums (net weight 450 lb/204 kg).

Storage & Handling

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.

Storage & Handling
  • Normal safety precautions (i.e., gloves and safety goggles) should be employed when handling STEOL CS-270 C. Contact with the eyes and prolonged contact with the skin should be avoided. Wash thoroughly after handling material.
  • The recommended dilution procedure for STEOL CS-270 C is to heat the precalculated water charge to 30-40 °C (86-104 °F). While agitating, add the STEOL CS-270 C at such a rate as to allow the product to dissolve without forming large gel masses. If excessive foam is generated, decrease agitation. All inorganic salts should be added once a clear solution of desired activity has been obtained.
  • It is recommended that STEOL CS-270 C be stored in sealed containers and kept at temperatures between 32-43 °C (90-110 °F). Avoid overheating or freezing. If material is frozen, heat mildly using warm water tracing.
  • Bulk Storage Information: Tanks, pumps, pipes and heat exchangers made of 316 stainless steel are recommended. Rotary piston type (positive displacement only) pumps are recommended. Recommended storage temperature for bulk tanks is 32-43 °C (90-110 °F).
