ALKATERGE - C
oil-soluble wetting agent
PROPERTIES
Just 1/2S Of 1% Of AMcaterge-C — that's all it takes to reduce the interfacial tension b e t w e e n n-hexane and w a t e r to one d y n e per centimeter. In mineral o i l , 0 . 1 % reduces the interfacial tension t o a p p r o x imately one to two dynes per centimeter. That's why A l k a t e r g e - C is such a successful oil-soluble wetting a n d auxiliary emulsifying agent. It's a sort o f chemical l e v e r — m a k e s it easy f o r the emulsifying agent to d o its job. This striking effect o n interfacial tension suggests many applications in connec tion with lubrication, extraction, and impregnating operations.

This non-volatile, a m i n e - t y p e compound reacts with acids to form salts and soaps which a r e themselves emulsifying and wetting agents. Salts of the mineral and l o w e r aliphatic acids a r e 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 a n d soaps have been used as wetting agents a n d penetrants in metal cleaners a n d in the processing and impregnating of textile a n d p a p e r products.

A ! k a t e r g e - C also has many uses b a s e d 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 , a n d it is also an excellent pigmentgrinding assistant in mineral oil vehicles.
