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 cationic 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 invention relates to a detergent for gentle removal of inks as used for marking in a roll mill, and to markers as used in production for temporary marking. According to the invention, the problem is solved by a detergent which permits the gentle removal of inks or markers from metallic surfaces in the form of a concentrate or a cleaning bath solution containing at least one water-immiscible solvent in an amount of 4 to 200 g/l, at least one anionic and/or nonionic surfactant in an amount of 8-300 g/l, at least one complexing agent in an amount of 1-100 g/l, at least one buffer substance in an amount of 1-100 g/l and at least one water-miscible solvent in an amount of 4-200 g/l in water.

A pH-stable dye which allows the penetration of hydrochloric acid into amorphically different carcinogenic fibers used for detection of sprayed asbestos or plastic mineral fibers for fireproofing components, is proposed. In the process, the continuous colored penetration of the fiber layers is achieved synchronously with the decomposition process of the hydrochloric acid. Thus, the progress of the penetration process can be estimated during the reconstruction work, and the task of removing the now spongy layers can be carried out with contrast agents of the following group consisting of organic and inorganic substances such as acridine orange, brilliant cresyl blue, bromophenol blue, eosin Y, erythrosine B, fluorescein, methyl blue, methyl orange, thymol blue resulting in the even penetration of carcinogenic fibers using hydrochloric acid.

Semiconductor-Oxides Nanotubes-Based Composite Particles Useful for Dye-Removal and Process Thereof, has been described in this invention, which relates to an innovative method, involving an ion-exchange mechanism operating under the dark-condition in an aqueous solution, for the processing of innovative products consisting of the nanotubes of semiconductor-oxides deposited on (or anchored to or attached to) the surface of flyash particles and metal-oxide (magnetic and non-magnetic) nanoparticles. The resulting micro-nano and nano-nano integrated composite particles find potential application in the removal of an organic synthetic-dye from an aqueous solution and industry effluent via the surface-adsorption process, involving the ion-exchange and electrostatic-attraction mechanisms, operating in the dark-condition. The novel composite particles can be recycled for the next-cycle of dye-adsorption by decomposing the previously adsorbed-dye on their surfaces via an innovative approach involving the use of either noble-metal-deposited photocatalyst or a magnetically separable magnetic photocatalyst and an exposure to the ultraviolet (UV) or solar-radiation.
