Abstract: A spray pump package capable of delivering two or more different predetermined spray patterns or spray characteristics through two or more different spray orifices, but at a liquid application amount per unit of area being treated which is optimum for the particular spray orifice selected rather than a compromise between two extremes. The predetermined spray patterns from which the end user may select may differ by any desired spray pattern or characteristic, including but not limited to: the cone angle of the spray; the width of the spray pattern; the average size of the particles in the spray; the amount of particle size deviation from the average; etc. The packages are provided with structure for automatically adjusting the maximum available pump stroke so as to optimize the maximum amount of product which can be delivered on each complete pump stroke for whichever orifice is selected by the end user.

Abstract: A liquid rinse aid for use in automatic dishwashing machines comprises a low foaming ethoxylated nonionic surfactant, an organic chelating agent, a hydrotrope-water solubilizing system and 0.1-10%, by weight of the rinse aid, of magnesium, zinc, tin, bismuth or titanium ions, added in the form of a water soluble salt.

Abstract: A detergent tablet comprising an alkaline salt is provided with a coating of a hydrated salt having a melting point in the range from 30.degree. C. to 95.degree. C. The coating is applied in the form of a melt of the hydrated salt so that a good coating is formed without the need for lengthy drying times. Preferred materials for the coating are sodium acetate trihydrate, sodium metaborate tetrahydrate and sodium orthophosphate dodecahydrate.
