Abstract: Machine dishwashing detergents comprising builder(s), surfactant(s), and optionally further ingredients, and furthermore 0.1 to 50% by weight of one or more nonionic surfactants which, in 80% strength by weight solution in distilled water, have a viscosity (Brookfield, spindle 31, 30 rpm, 20° C.) of less than 450 mPas.

Abstract: A method for washing dishes containing colored soil is presented involving contacting the dish surface with a dishwashing detergent containing a peroxygen compound and an activator compound of the formula R1R2R3N+CH2CN X− where R1, R2 and R3 independently of one another represent an alkyl, alkenyl or aryl group containing 1 to 18 carbon atoms, and wherein R2 and R3 may be part of a heterocycle including the N atom, and X is an anion, to form an aqueous dishwashing detergent. The method is useful for washing colored stains from crockery and cutlery, and is effective at temperatures below 80° C.

Abstract: A fluidized bed apparatus for the production and treatment of granules and a method for its operation is provided. The fluidized bed apparatus includes an entry chamber through which a gas is designed to flow upwards; a fluidization chamber for fluidizing the material located above the entry chamber; pivotal slats located between the entry chamber and the fluidization chamber; and a nozzle arm located in the chamber below the slats with a nozzle line ending in a nozzle which is directed into the fluidization chamber through cutouts in the slats and extends partly into the fluidization chamber. The fluidized bed apparatus has rigid nozzle arms and lines which are easily jacketed for heating and cooling applications.

Abstract: An aqueous alkaline composition for cleaning equipment used in the food industry wherein the composition contains potassium hydroxide or a mixture of potassium hydroxide and sodium hydroxide and wherein the potassium hydroxide is present in an amount of at least 20% by weight, based on the weight of hydroxide present in the composition. A process for regenerating the cleaning solution is also disclosed.

Abstract: Naphthalene sulfonic acid/formaldehyde condensates (i) may be used in a composition for cleaning hard surfaces to reduce the rain effect and/or the film effect, (ii) may be present in a cleaning composition for hard surfaces in combination with one or more other anionic and/or nonionic surfactants and (iii) may be used in a process for reducing the rain effect and/or the film effect on a hard surface treated with a liquid cleaning composition, the surface being treated with a liquid cleaning composition in concentrated or diluted form containing one or more naphthalene sulfonic acid/formaldehyde condensates.

Abstract: Described are mouth and dental care preparations with improved action against the formation of plaque and containing as their active ingredients sulfophosphoric acid salts of the formula (I): ##STR1## in which R.sup.1 and R.sup.2, independently of each other, are hydrogen, or the cation M.sup.(+) and R.sup.2 together form the group(OC.sub.n H.sub.2n).sub.x --O--R.sup.3 --SO.sub.3.sup.(-) M.sup.(+),R.sup.3 is an alkylene, hydroxyalkylene or alkenylene group with 8-22 C-atoms, n=2 or 3, x=0 or a number between 1 and 30 and M.sup.(+) is an alkali metal ion, the ammonium ion or a mono-, di- or trialkanolammonium ion with 2-4 C-atoms in the alkanol group. The preparations inhibit in vitro the dissolution and crystal growth of hydroxyapatite.

Abstract: Drinking water, mixed feeds and/or fodders for laying hens having a content of essential oils for improving the flavor of the hen' eggs.

Abstract: This invention is directed to novel antimicrobial agents. More particularly, this invention is directed to 2-(3-iodo-2-propynyloxy)-ethyl carbamates of the formula ##STR1## wherein R is hydrogen, linear or branched alkyl of from 1 to 12 carbon atoms, cycloalkyl of from 4 to 8 carbon atoms, aryl, substituted aryl, aralkyl, or arylsulfonyl;R.sup.1 and R.sup.2, which may be the same or different, each are hydrogen, linear or branched alkyl or alkenyl of from 1 to 6 carbon atoms, or cycloalkyl of from 5 to 7 carbon atoms, or R.sup.1 and R.sup.2, taken together, represent --(CH.sub.2).sub.m --, in which m is an integer of from 4 to 6; andR.sup.3, R.sup.4, R.sup.5, and R.sup.6, which may be the same or different, each represent hydrogen, alkyl of from 1 to 4 carbon atoms, or aryl, or CCl.sub.3, or R.sup.3 and R.sup.5 or R.sup.4 and R.sup.6, taken together, represent --(CH.sub.2).sub.n --, in which n is an integer of from 3 to 5,as well as a process for their preparation and their use as antimicrobial agents.
