PROPERTIES
Just 1 / 2 5 Of 1% Of AIkaterge-C — that's all it takes to reduce the interfacial tension between n-hexane a n d w a t e r t o one d y n e per centimeter. In mineral oil, 0 . 1 % reduces the interfacial tension t o a p p r o x imately one t o t w o dynes per centimeter. That's why A l k a t e r g e - C is such a successful oil-soluble wetting and auxiliary emulsifying agent. It's a sort of chemical lever—makes it easy for the emulsifying agent t o do its job. This striking effect on interfacial tension suggests many applications in connection with lubrication, extraction, and impregnating operations.

This non-volatile, amine-type compound reacts with acids to f o r m salts and soaps which a r e themselves emulsifying and wetting agents. Salts o f the mineral a n d lower aliphatic acids are water-soluble. W i t h the higher f a t t y acids, A l k a t e r g e - C forms oil-soluble soaps. These salts and soaps have been used as wetting agents and penetrants in metal cleaners a n d in the processing a n d impregnating of textile and p a p e r products.
Solubility in Water Less than 0.002% by weight in Mineral and Vegetable Oils Miscible in Organic Solvents Miscible with naphtha, benzene, kerosene, carbon tetrachloride, ethyl acetate, acetone, methanol, butanol, and most other organic solvents.
Alkaterge-C also has many uses based on its acid-accepting a n d surface-active properties. It is an effective anti-foam agent, especially when used in conjunction with mineral o i l , and it is also an excellent pigmentgrinding assistant in mineral oil vehicles.
