Solubility. . . Miscible w i t h water in all proportions. Soluble in many nonpolar solvents. Functions well wherever a surfactant would be desirable in oils or aliphatic solvents. Other Promising Characteristics . . . Valuable intermediate for sulfation. Conversion produces high-foaming active ingredients especially suited for liquid detergents. Unreacted, it is a low-foaming surfaceactive agent for use per se and an excellent emulsifier. Typical uses . . . In liquid detergents, emulsi fiable toxicant concentrates, metal cleaning and treating compounds; as a paper rewetting agent and an e m u l s i f i e r in a v a r i e t y of applications.

Solubility- · · Soluble in water and most polar solvents, but generally insoluble in nonpolar solvents.
Solubility... Soluble in water and most polar solvents, b u t generally insoluble in nonpolar solvents.
Solubility . . More soluble than Sterox N J . Especially useful in solutions containing inorganic salts or S A N T O M E R S E ® alkyl aryl sulfonates.
Other Promising Characteristics- · · Low foam a n d high chemical s t a b i l i t y a r e combined with effective functional p r o p e r t i e s a n d ease of use. Lack of odor typically associated with this type of surfaceactive material makes perfuming easier—helps build market appeal for your products.
