Abstract: A dispenser for powdered, granular, pellet, briquette or tablet-like material is provided. The dispenser includes a dispenser head through which the material dissolved in water can be dispensed. A spray device is provided at the head to spray water onto the material provided in the dispenser head. A suspension device is provided to suspend a bag containing the material above the dispenser head. The bag in its suspended orientation has a fastener along the bottom end which closes the bottom end of the bag. The fastener is not, however, releasable until after the bag is mounted in the dispenser. Then the fastener is releasable to allow the contents thereof to fall by gravity onto the dispenser head. The dispenser provides a system, which normally avoids contact of the toxic contents of the bag with the user. At the same time, the only waste is in the form of a bag which may be made of recyclable plastic, hence minimizing waste associated with the system.

Abstract: Chemical etching of bottles in a bottle washer is minimized by soaking the bottles in a highly caustic composition which does not include any phosphorus compounds, ethylene diamine tetraacetic acid or nitrilotriacetic acid. The soaking composition includes the sodium hydroxide dissolved in water, in combination with polycarboxylic acid crystal growth inhibitors. Preferably, the soaking solution further includes a nonionic surfactant such as an alkyl polyglucoside, as well as a chelant such as a gluconate, glucoheptonate, or boroheptonate. The soaking solution can be added by either combining a liquid or powder built detergent composition which also forms a portion of the present invention or, alternately, an additive package, not including the sodium hydroxide, can be added. These compositions effectively clean the bottles and significantly reduce the dissolution of the glass which can, in turn, cause a hazing and weight loss.

Abstract: Improved light duty cleaning compositions comprising 15-50% surfactant on product can be formulated such that they comprise, on surfactant:a) 50-70% wt of a mixture of primary alkyl sulphate and alkyl ether sulphate, wherein the average ethoxylation value of the mixture is 0.5-2.5,b) 2-8% wt of a betaine, an amine oxide or a mixture of betaine and amine oxide, and,c) 25-45% wt of an alkylpolyglucoside surfactant.It is believed that compositions which have an excess in surfactant of a mixture of both primary alkyl sulphate and alkyl ether sulphate in a specified ratio, i.e. such that the total EO is 0.5-2.5, together with a lesser, but significant level of APG and a minor amount of betaine, provide an acceptable combination of mildness, cleaning and foaming under a broad range of conditions and show surprising benefit in a bowl-wash situation.

The diacetic acid is desirably in the form of a divalent metal complex thereof. A process is also provided for removing a zinc containing acrylate polymer film from a floor surface, wherein a floor stripper composition of the invention is applied. A good floor stripper performance could be obtained with this composition owing to its low foaming behaviour.

Abstract: An all-in-one cooling water treatment composition includes a high concentration of peroxide, preferably hydrogen peroxide, in combination with a polyhydric alcohol and a phosphonate to stabilize the peroxide in a concentrated solution. The composition further includes a yellow metal corrosion inhibitor such as aromatic triazole and optionally polymeric dispersants and ferrous metal corrosion inhibitors and/or molybdate metal corrosion inhibitors. In this composition the phosphonate, preferably HEDP, acts both to stabilize the peroxide and, at the same time, provides anti-scalant treatment for the cooling tower. Due to the stability provided by the HEDP and its anti-scalant properties, this can be formulated as an all-in-one treatment composition which is stable at high concentrations and can be added to effectively control biocidal activity, scale and corrosion.
