BIO-TERGE AS-40
CAS Registry No. 68439-57-6
INCI Name : Sodium C14-16 Olefin Sulfonate
Applications
BIO-TERGE AS-40 is an aqueous solution of sodium olefin sulfonate which is produced by the continuous sulfonation of alpha olefins via Stepan's falling film process. Stepan's process minimizes the formation of disulfonates thereby offering a consistent high quality product.
BIO-TERGE AS-40 is an ideal surfactant for a variety of detergent and personal care applications including hand soaps, shampoos, and bath products. It offers the formulator excellent viscosity and foam characteristics, as well as improved mildness over lauryl sulfates. It is more stable than alcohol sulfates over a broad pH range.

Health Effects
BIO-TERGE AS-40 is slightly toxic orally (LD50 = 1.3-2.4 g/kg) in rats and causes moderate skin and eye irritation at 10% active.
Storage & Handling
Normal safety precautions (i.e. the use of gloves and safety goggles) should be employed when handling
BIO-TERGE AS-40. Contact with the eyes and prolonged contact with the skin should be avoided. Wash thoroughly after handling material.
It is recommended that BIO-TERGE AS-40 be stored in sealed containers and kept at temperatures above 50°F (10°C). Avoid overheating or freezing. This material can gel and separate if exposed to cooler temperatures. Heat it slowly with mild agitation to insure its homogeneity before use.
Bulk Storage Information: Tanks made of 316 stainless steel or fiberglass with Atlac 382 corrosion liner are recommended. Positive displacement gear pumps and piping should be 316 stainless steel. Recommended storage for bulk tanks is 80-100°F (27-38°C).
Standard Packaging: BIO-TERGE AS-40 is available in bulk and 55 gallon drums (450 lb/204 kg).
