New S T E R O X D F , D J , N J and N L were developed to give consistent performance and genuine economy. T h e y are stable in acidic and alkaline media, even a t elevated temperatures, and are effective in both hard and soft water. T h e y provide specific advantages where low odor, light color and good deter gency are wanted; and also where emulsification, wetting, foaming characteristics or liquid-solid contact is important.

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 u s e s . . . In liquid detergents, emulsifiable toxicant concentrates, metal cleaning and treating compounds; as a paper rewetting agent and an emulsifier 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, but generally insoluble in nonpolar solvents.
Solubility . . More soluble than Sterox NJ. Especially useful in solutions containing inorganic s a l t s or S A N T O M E R S E ® alkyl aryl sulfonates.
Other Promising Characteristics. . . Low foam and high chemical stability are combined with effective functional properties and ease of use. Lack of odor typically associated with this type of surfaceactive material makes perfuming easier—helps build market appeal for your products.
Other Promising Characteristics. . . Exceptionally light colored, this "wheel horse" nonionic is effective per se as an emulsifier and as a lightduty detergent for hard surfaces. In combination with SANTOMERSE alkyl arylsulfonates, it exhibits foamstabilizing effects, and produces a denser foam than that obtained with alkyl aryl sulfonates alone.
Other Promising Characteristics,. . . Primarily designed for use in liquid detergents. Exceptionally valuable for this application in combination with Monsanto T K P P . Effective per se as an emulsifier and light-duty detergent for hard surfaces. In combination with S A N T O M E R S E alkyl aryl sulfonates, it exhibits foamstabilizing effects and produces a denser foam than that obtained with alkyl aryl sulfonates alone.
Typical uses- • . In liquid and powdered detergents, chemical processing, textile dyes and scouring agents, and numerous compounds for metal cleaning and treating, paper de-inking, felt washing and other wet processing operations.
Typical uses. . . In liquid and powdered detergents, insecticides, and in numerous compounds for textile, paper and leather processing, chemical processing, petroleum acidizing and secondary recovery.
Typical uses.. . In liquid detergents, industrial cleaners, textile scouring and soaping-off compounds, many specialty products; as a post-polymerization latex paint stabilizer.
