Disclosed are antimicrobial sacrificial floor coatings systems including an antimicrobial sacrificial floor coating composition capable of reducing and/or preventing gram positive and gram negative bacterial growth on floors. Also disclosed is an antimicrobial sacrificial floor coating remover being readily capable of removing the antimicrobial sacrificial floor coating as desired from previously treated flooring surfaces. In certain aspects, the antimicrobial sacrificial floor coatings can include a nonionic acrylic polymer; a nonionic wax; and a cationic alkyl biguanide or salt thereof. The antimicrobial sacrificial floor coating may further include a cationic wax that further stabilizes the system during storage, application, and/or post-application to a floor surface. The antimicrobial sacrificial floor coating composition has a pH of less than 7 while exhibiting continuous antimicrobial properties from full cure on a floor surface up to 1 year post-application to the floor surface at a minimum contact time of 1 hour.

The present invention relates to a method for removing a foreign material from the surface of an article comprising the following steps: i) providing an article having a surface covered at least partly with a foreign material; ii) contacting the article provided in step i) with a cleaning medium being an acid having a pKa in the range from −10 to 7 having a minimum concentration of 1 wt.-% and with a carrier medium having a density different from the density of the cleaning medium to obtain a mixture comprising the foreign material solved and/or dispersed in the cleaning medium, the carrier medium and the article free from the foreign material; iii) allowing the mixture obtained in step ii) to separate to obtain a heterophasic emulsion comprising at least a first phase comprising the carrier medium and the article free from the foreign material and a second phase comprising the cleaning medium and the foreign material solved and/or dispersed therein; iv) separating the phases obtained in step iii); and v) separating the article free from the foreign material from the carrier medium. Furthermore, the present invention relates to an installation for carrying out the inventive process.

A composition for paint removal and methods of making and of using the composition are provided. The paint remover composition comprises a component selected from the group consisting of THF, toluene, acetone, DMSO, dioxalane, 1,2 trans dichloroethylene, and a combination thereof.

A graffiti removal system and a method of removing graffiti are provided.The graffiti removal system comprises a liquid comprising 4-50 wt % glyceride wherein the glyceride is the condensation reaction product of at least 1.10 moles of a mixture of acids to no more than 2.1 moles of the mixture of acids per mole of glycerin. The mixture of acids comprises at least 0.275 to no more than 0.990 moles of a first acid comprising a branched acid with 16-20 aliphatic carbons; at least 0.250 to no more than 0.810 moles of a second acid comprising an alkyl acid with 9-11 carbons and at least 0.250 to no more than 0.810 moles of a third acid comprising an alkyl acid with 7-9 carbons. The third acid has a lower molecular weight than the second acid. The graffiti removal system also has 6-45 wt % surfactant, optionally up to 5-90 wt % graffiti removal agent and up to 90 wt % solvent. The liquid has a BYV of at least 50 dyn/cm.sup.2.

Disclosed is a liquid mixture (preferably an oil-in-water emulsion) for cleaning spilled paint, varnish, dye and/or surface coating, and a cleaning method comprising a step of applying said mixture to a fresh stain left by paint, varnish, surface coating and/or dye.

A cleaning liquid includes water, a surfactant, and glycol ether. The surfactant is an acetylene surfactant or a silicone surfactant. A content ratio of the glycol ether is at least 5% by mass and no greater than 15% by mass relative to a mass of the cleaning liquid. Preferably, a contact angle of the cleaning liquid to an austenitic stainless steel plate is no greater than 40 degrees.

A paint remover composition and methods of making and using are provided. The composition has a primary ether or acetyl solvent with a molar volume of <100 cm.sup.3/mol, and an amine with a molar volume of <100 cm.sup.3/mol.

Compositions and methods of the invention are directed to the removal of solid films, and particularly paint layers, from substrates, and particularly smooth, porous, and/or mineralogically fragile substrates such as sandstone. The compositions include cooked aqueous solutions of starch. The compositions can advantageously remove paints and other unwanted solid films from these and other substrates without damaging the substrate itself.

The disclosure relates to ink compositions for digital printing on an external surface of a plastic article. The ink compositions comprise an ink removal-promoting additive. In some aspects, the ink removal-promoting additive can facilitate the separation or loosening of the image from the external surface of the article when the image is exposed to a liquid-based solution at an elevated temperature. Also disclosed are recyclable plastic articles having an external surface with an image printed thereon using the disclosed ink composition and methods for removing cured ink from a plastic container. This abstract is intended as a scanning tool for purposes of searching in the particular art and is not intended to be limiting of the present invention.
