Abstract: A composition, which can prepare hypochlorous acid water having a pH of 5 to 7.5, a concentration of hypochlorous acid of 50 to 500 ppm, a concentration of free chlorine molecules lower than an effective chlorine concentration, the concentration of free chlorine molecules of 20 ppm or less, and a nonionized hypochlorous acid as an active ingredient when diluted with an aqueous vehicle, the composition comprising: 1) one or more selected from trichloroisocyanuric acid, dichloroisocyanuric acid and salts thereof; and 2) a buffer salt (provided that, a chlorite of an alkali metal or alkaline earth metal is included in neither the aqueous medium nor the composition).

Abstract: A quantitative test method for determining the content of a heat transfer oil mixed with a polar edible oil or fat, wherein the polar edible oil or fat containing a trace amount of the heat transfer oil is diluted with a nonpolar organic solvent, said edible fat or oil is adsorbed onto a column packing medium by passing the dilute solution thereof through a separation column, the heat transfer oil is allowed to flow out from the separation column together with the nonpolar organic solvent, the solution that has thus flowed out is concentrated and subjected to gas chromatography, and a quantitative determination is performed by comparison with the gas chromatography analysis value of a reference solution of heat transfer oil.

Abstract: An ink jet recording material having a high gloss and capable of recording thereon ink images having high color density and clarity, has an ink-receiving layer formed on a substrate and including a binder and secondary particle having an average size of 10 to 300 nm and including a plurality of primary particles of silica prepared by wet method and/or aluminosilicate agglomerated with each other without binder, and can be produced by forming the ink-receiving layer on a shaping base, bonding the substrate to the ink-receiving layer on the shaping base and separating the resultant laminate from the shaping base.
