Abstract: An aqueous composition for softening or removing organic coatings comprises: (a) an effective amount of a mixture of (a1) at least one non-toxic compound of formula (I), wherein R, R and R , which may be the same or different, represent lower alkyl, phenyl or lower alkyl-phenyl groups (e.g. triethylphosphate), and (a2) at least one non-toxic lower alkyl ester of a C2-20 carboxylic acid or at least one non-toxic C4-12 alkanol (e.g. dimethyl succinate, diethyl succinate, dimethyl adipate, 1,2,3-propanetriol triacetate, tri-n-butyl citrate, n-octyl acetate or methyl octanoate); (b) an effective amount of at least one surfactant to allow the composition to exist as a stable emulsion, the surfactant(s) being selected from nonionic water-soluble block copolymers of more than one alkylene oxide (e.g. Synperonic PE (F-series)); and (c) water; characterised in that component (c) (water) is present in an amount of less than about 50 % by weight and/or volume of component (a) and in that the composition exists as a stable microemulsion.
