Abstract:
An aqueous emulsion composition for plasticizing or softening paint, varnish and similar coatings prior to stripping the coating from a surface, the composition comprising:(a) a emulsified hydrophobic phase comprising a plasticizing/softening mixture,(b) an effective amount of at least one water-soluble block copolymer surfactant of more than one alkylene oxide to stabilize the emulsion,(c) an aqueous phase including water in an amount sufficient to comprise the major portion of the composition; and said emulsified hydrophobic phase suspended in the aqueous phase, the hydrophobic phase including components (a1) and (a2) as defined below:(a1) at least one compound of formula I: ##STR2## wherein R, R.sup.1 and R.sup.2, which may be the same or different, represent unsubstituted mono-substituted or poly-substituted C.sub.1-8 alkyl, phenyl or (C.sub.1-8 -alkyl)-phenyl groups; and(a2) about 4% to about 10% by weight of total composition of at least one unsubstituted mono-substituted or poly-substituted C.sub.1-8 alkyl ester of a C.sub.2-20 carboxylic acid; or about 4% to about 10% by weight of the total composition of at least one C.sub.4-12 alkanol;wherein said mono-substituted or poly-substituted C.sub.1-8 alkyl consist of one or more substitutents selected from the group consisting of halo, nitro, amino, C.sub.1-4 alkylamino, di-C.sub.1-4 alkylamino, hydroxy, C.sub.1-4 alkoxy, carboxy, (C.sub.1-4 alkyl)carbonyl, (C.sub.1-4 alkoxy)-carbonyl, C.sub.2-4 alkanoyloxy, (C.sub.1-4 alkyl) carbamoyl, aryl, cycloalkyl and salts thereof.
