Compsns. for cleaning agricultural sprayers - contg. surfactant, solvent and fat solubilisers

摘要

Cleaning compsns. for removing plant protection agent residues from agricultural spraying devices comprise a mixt. of one or more surfactants (I), a solvent for (I), a fat solubiliser (II) and a carrier. Pref. (I) is a mixt. of an ethroxylated polyarylphenol phosphate (Ia) and a polyoxypropylene/ polyoxyethylene copolymer (Ib). The solvent for (I) is n-BuOH. (II) is an 'alkylenephenylsulphonic acid' in Ca salt form. The carrier is water, opt. contg. ethylene glycol (III) as antifreeze. The compsns. comprise 5-15% (Ia), 3-12% (II), 3-12% (II), 1-5% n-BuOH, 2-5% (III), balance water. ADVANTAGE - The compsns. have good cleaning properties and are stated to be biodegradable.
