Sodium Alpha-Olefin Sulfonate CAS 68439-57-6

Sodium Alpha-Olefin Sulfonate (AOS) is supplied as an anionic surfactant derived from alpha-olefins through sulfonation, widely used in detergent and cleaning formulations. It provides strong detergency, good foaming performance, and effective wetting properties, making it suitable for both household and industrial cleaning systems.

In commercial supply, AOS is typically available as an aqueous solution (commonly around 35–40% active matter) or as spray-dried powder, allowing flexibility for different formulation processes. It is used in liquid detergents, powder detergents, personal care cleansers, and industrial cleaning agents. Standard packaging, batch documentation (COA, TDS, SDS), and supply support are available for both formulation development and bulk production.

Packaging

Sodium Alpha-Olefin Sulfonate is supplied in both liquid and solid forms depending on application requirements. Liquid grades are packed in plastic drums, IBC containers, or bulk tanker systems, while powder grades are packed in moisture-resistant bags or bulk containers. Packaging is designed to maintain product stability and prevent contamination during storage and transport. Configurations can be arranged according to order quantity and logistics needs.

Storage

Store in a cool, dry, and well-ventilated area. Keep containers tightly closed when not in use to prevent contamination and moisture variation. Avoid prolonged exposure to high temperatures and direct sunlight. For liquid forms, prevent freezing conditions; for powder forms, protect from humidity to avoid caking.
