Abstract: The present invention provides a lubricating oil for a compression type refrigerator including a polyvinyl ether-based compound containing an alkylene glycol or polyoxyalkylene glycol unit and a vinyl ether unit in a molecule and having a molecular weight in a range of 300 to 3,000; and an organic carboxylic acid ester of a polyhydric alcohol in which the ester contains two or more free hydroxyl groups. The lubricating oil for a compression type refrigerator of the present invention has high miscibility and high viscosity index, and is excellent in wear resistance and also corrosion prevention property under carbon dioxide atmosphere.

Abstract: The present invention relates to an article comprising: (a) a liquid composition comprising: (i) enzyme; and (ii) from 0% to 10% (by weight of said liquid composition) free water, preferably 0% to 5% free water; and (iii) carboxylic acid comprising 5 carbon atoms or less, and 1 or 2 carboxy groups; and (iv) chelating agent; and (v) enzyme stabilizing metal ion system consisting of calcium ions and magnesium ions, present in a weight ratio of calcium ion to magnesium ion of from 1:1 to 4:1; and (vi) from 0% to 0.2% (by weight of said liquid composition) source of borate ions; and (b) a water-soluble polymeric material that is capable of being cross-linked by borate ions, preferably a water-soluble polymeric material comprising poly-vinyl alcohol.
