The present invention provides cleaning solutions for removing ink, coating, varnish, adhesive, etc. residue from printing equipment. The cleaning solutions of the present invention comprise one or more solvents, preferably selected from acetoacetates, alcohols, glycol ethers, glycol esters, terpenes, and water, and are preferably free of surfactants. The cleaning solutions of the invention have a relative evaporation time (RET) of less than 60 seconds, and a ratio of the RET to the radius of the sphere of solubility of the resin in the ink to be removed of less than 6.

Provided are compositions containing alkyl esters derived from triglyceride oils produced from genetically engineered microalgae. Specific embodiments relate to esters derived from oils with high C10-C12 fatty acid profile. Compositions comprising the esters include cleaning products, completion fluids, work-over fluids, drilling fluids, metal working fluids, lubricants, paints, and inks.

A method of cleaning highway and road construction equipment is disclosed.

The testing of various chemicals has yielded new chemicals and chemical mixtures for the use of removing carbon deposits from the internal combustion engine. Some of these chemicals and chemical mixtures have proven to work better across many different carbon types than other chemicals that were tested. These chemical terpenes are typically produced from plants. One standard terpene mixture is known as turpentine. The chemical turpentine and chemicals found in turpentine have been determined, through our research and testing, to be extremely effective at removing the carbon that is produced within the internal combustion engine.

Compositions and methods for cleaning surfaces, such as for removing residues or other coatings from molds and other industrial parts, such compositions comprising, for example, a first solvent comprising a pyrrolidone such as 2-pyrrolidone, 1-(2-hydroxyethyl)-2-pyrrolidone, or mixture thereof; and a second solvent selected from the group consisting of an imidazole (such as 1,2-dimethylimidizole), an alkylene glycol ether (such as ethylene glycol monobutyl ether or diethylene glycol monobutyl ether, a terpene (such as d-limonene), and mixtures thereof. In various embodiments, such methods are for removing residues from molds used in forming polyurethane parts, wherein residues comprise polyurethane, urethane reactants, and mold release agents. The compositions may be substantially free of 1-methyl-2-pyrrolidone and of 1-ethyl-2-pyrrolidone.

A suctionable gel for eliminating a contaminating species contained in an organic layer on the surface of a material, consisting of a colloidal solution comprising, preferably consisting of: 1 wt % to 25 wt %, preferably 5 wt % to 20 wt % based on the total weight of the gel, of at least one inorganic viscosifying agent; 13 wt % to 99 wt %, preferably 80 wt % to 95 wt % based on the total weight of the gel, of an organic solvent selected among the terpenes and the mixtures thereof; optionally, 0.01 wt % to 10 wt %, based on the total weight of the gel, of at least one dye and/or pigment; optionally 0.1 wt % to 2 wt %, based on the total weight of the gel, of at least one surfactant. The disclosure further relates to a decontamination method using the gel.
