Amino-Carboxylic Amphoteric Surfactants in Alkaline Cleaners

Abstract

A study was made of amino-carboxylic amphoteric surfactants in soak type alkaline cleaners suitable for use with aluminum and magnesium (nonferrous) alloys as well as with ferrous materials. Compounds were developed possessing the "improved detergency" necessary for the removal of asphalt and mineral oil soils. The surfactant portion of such compounds may consist of as little as 1.0 percent of the partial sodium salt of N-lauryl beta iminodipropionate plus 1.0 percent of a polyethanoxy nonyl phenol (15-30 ethylene oxide mole ratio). Galvanic corrosion tests using magnesium-aluminum couples indicated satisfactory behavior of the aluminum, the anodic member of the couple, as well as of the magnesium. The developed cleaners meet all the performance requirements of Fed. Spec. P-C-436a (Cleaning Compound, Alkali Type) except surface tension.
