The Use of Soft Detergents in P-C-436b and P-C-437 Cleaners,
Abstract
Anticipating Federal legislation banning the use of hard detergents, a feasibility study was made of the substitution of commercially-available, soft detergents in alkaline soak, hydrosteam, and high pressure steam cleaners of Federal Specifications P-C-436b and P-C-437. P-C-436b cleaners based on surfactant mixtures of an ethoxylated straight chain alkyl phenol or alcohol with a straight chain ABS met the specified performance requirements. Soft ABS slurries (ca 50% liquid) were not suitable because they induced severe caking. Sodium lauryl sulphate and amphoterics of the quaternary imidazolium hydroxide and amino-carboxylate types, when used with soft nonionic ethoxylates, also gave satisfactory P-C-436b compounds. P-C-437 cleaners formulated with ethoxylated straight chain alcohols or alkyl phenol compiled with the performance requirements of the specification. (Author)
