  • Patent number: 7468345
    Abstract: A concentrated non-aqueous cleaning solution having a long shelf life includes an ester and an anhydrous surfactant. The ester is the active ingredient for dissolving graffiti, grease and other contaminants. The ester can be one of or a mixture of dimethyl glutarate, dimethyl succinate, dimethyl adipate, ethyl lactate, and a methyl ester extracted from soybean oil. The anhydrous surfactant is preferably alcohol ethoxylate. The ester in the concentrated solution does not degrade into an acid and alcohol as long as the solution is not mixed with water. This allows the concentrated solution to be shipped and stored and remain efficacious. The concentrate can be diluted with water immediately prior to use. Diluting before use makes the graffiti cleaner less expensive and prevents damage to sensitive surfaces but does not provide long enough time for the ester to degrade.

  • Patent number: 6417149
    Abstract: A paint stripping composition comprising methyl benzoate and formic acid, as well as a method for using the foregoing composition in stripping paint from a substrate, are disclosed. The paint stripping composition may optionally also comprise thickeners, surfactants, and corrosion inhibitors. The composition and method are useful in stripping a variety of paints and similar organic coatings from both metallic and non-metallic substrates. Most preferably, the paint stripping composition does not comprise n-methyl-2-pyrrolidone.

  • Patent number: 6369010
    Abstract: The present invention is a method and composition for preventing the deposition of contaminants from resinous pulp and/or recycled pulp in the press section of a pulp and paper process. The composition of the invention includes a cleaning solvent comprising a blend of aromatic hydrocarbons containing between nine and eleven carbon atoms and a surfactant comprising an alcohol ethoxylate. The composition of the invention can be applied to the felts in the press felt section of a pulp and paper process to break down and loosen deposited contaminants and the contaminants can be removed thereby preventing the need for batch cleaning and downtime in the press felt section.

  • 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.
