  • Patent number: 9884972
    Abstract: An aqueous composition for cleaning surfaces, for removing coatings from surfaces, or for plasticizing or softening coatings or other surface-adhered materials prior to stripping or mechanical removal thereof from the surface, comprises a trialkyi or triaryl phosphate, a dibasic or tribasic carboxylic acid ester, and greater than 80% by weight of water. The composition is useful in removing grease, waxes, oil, resins, tar, ink, magic marker ink, paint (including spray-paint), varnish, lacquer, stains (including wood staining compositions applied to a wooden surface), dirt, mold or foodstuffs from surfaces.

  • Patent number: 6339053
    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, R1 and R2 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 C2-20 carboxylic acid or at least one non-toxic C4-12 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.
