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. triethlyphosphate) and (a2) at least one non-toxic lower alkyl ester of a C carboxylic acid or at least one non-toxic C alkanol (e.g. diethyl succinate, diethyl succinate, diethyl 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 nonionic water-soluble block compolymers of more than one alkylene oxide (e.g. Synperonic PE™ (F-series)): and (c) water, characterized 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.
