An activator composition having increased effectiveness and life when used in an aqueous alkaline stripper solution at elevated temperatures to remove siccative coatings from substrates containing two essential components A and B. Component A consists essentially of at least one of an ethoxylated tetrahydrofurfuryl, a mixture of an ethoxylated tetrahydrofurfuryl and an ethoxylated furfuryl, N-methyl-2-pyrrolidone and N-(2-hydroxyethyl)-2-pyrrolidine. Component B consists essentially of at least one of N-phenyl-diethanolamine, furfurylamine, tetrahydrofurfurylamine, octadecylamine, butoxypropanolamine and N-amino-morpholine.

An aqueous alkaline composition having increased effectiveness and bath life when used at elevated temperatures to remove siccative coatings from substrates coated therewith containing one or more alkaline compounds and at least two of the following three materials: tetrahydrofurfuryl alcohol, an ethoxylated furfuryl alcohol and an ethoxylated tetrahydrofurfuryl alcohol; and preferably containing one or more of a sequestering agent, a composition-stabilizing compound, and a surfactant.

Low foaming acid sanitizer compositions containing anionic surfactants which normally exhibit high-foaming, e. g. dodecyl benzene sulfonic acid, are obtained by incorporating in the composition a foam suppressant combination of a C. sub. 8 -C. sub. 18 -aliphatic alcohol, or a C. sub. 9 -C. sub. 12 -alkyl-phenol, e. g. tridecyl alcohol and a polyvalent metal salt, e. g. aluminium sulfate. The usual solubilizers such as propylene glycol and isopropyl alcohol can be present as optional ingredients. Anti-microbial properties of the composition are not adversely affected by the foam suppressants and the compositions exhibit low foaming even in deionized water.
