Abstract: A paste-form to solid detergent composition is provided consisting of a) 21 to 70 percent by weight of an aqueous lye solution having a concentration of 42 to 55 percent by weight of lye; b) 0.5 to 40 percent by weight of one or more alcoholates of ethanol, propanol, isopropanol, glycerol or butyleneglycol, and c) 10 to 35 percent by weight of water. The detergent is a high alkaline detergent, useful for cleaning hard surfaces.

Abstract: The process of dishwashing in an institutional dishwashing machine by adding to the wash liquor of the dishwashing machine a low-alkali content detergent composition and adding to a washing tank of the dishwashing machine a detergency booster composition containing an enzyme. Apparatus to practice the process is also disclosed.

Abstract: A water-containing solid detergent having a delayed, controllable and variable hardening time after addition of all the components produced by providing a) aqueous 42 to 55% lye, in a quantity of 21 to 70% by weight, b) mixing with the aqueous lye a compound selected from the group corresponding to formula (I): HOCH2CH(R1)OR2  (I) in which R1 is a hydrogen atom or a methyl group and R2, independent of R1, is a hydrogen atom, a C1-4 alkyl group, a group CH2CH(R3)0R4 or a group CH2CH(R5)OCH2—CH(R6)OR7, where R3, R5, and R6 represent hydrogen atoms or methyl groups and R4and R7 represent hydrogen atoms or C1-4 alkyl groups, and compounds corresponding to formula II: [HOCH2CH(R8)3−xNHx  (II) in which R8 is a hydrogen atom or a methyl group and x is the number 0, 1 or 2, in a total quantity of 0.

Abstract: A water-containing compact detergent composition having a controllably variable strength containing an aqueous lye solution, a viscosity increasing agent selected from a compound corresponding to formula I or formula II HOCH2CH(R1)OR2   (I) [HOCH2CH(R8)3-xNHx  (II) and a solid alkali metal hydroxide. The product is useful in domestic or institutional dishwashing machines.

Abstract: The invention concerns a liquid agent in suspension for use in washing-up machines. The aim of the invention is to ensure the consistency of a paste without the need to use thickeners or extenders. This is achieved by using 30 to 60% by weight of water, 15 to 70% by weight of an alkali-metal tripolyphosphate selected from sodium tripolyphosphate, used either in the anhydrous or the partly hydrated form, and potassium tripolyphosphate in the presence of 5 to 30% by weight of an alkali carrier such as an alkali-metal hydroxide, carbonate, or metasilicate, if necessary in the presence of active-chlorine carriers, complex carriers and the other usual auxiliaries.

Abstract: Transport- and storage-stable paste-form detergents based on sodium hydroxide that are easily processed and handled are obtained by thickening concentrated aqueous sodium hydroxide preparations with glycols, glycol derivatives, alkanolamines, or alkanolamine derivatives. The detergents also can contain builders and other typical detergent composition ingredients.

Abstract: The aliphatic primary alcohols are reacted with a glycose, more especially glucose, in the presence of an acidic catalyst in certain process steps so that particularly light-colored and alkali-stable alkyl glucosides are obtained after a subsequent, compulsory bleaching step, which represents an improvement over known direct synthesis processes. The process may be carried out both on a laboratory scale and also on an industrial production scale.

Abstract: A process for the production of surface-active alkyl glycosides which is carried out by the transacetalization method with butanol, leads to a new alkyl glycoside as end product which is characterized by high color-stability in alkaline medium; besides a high proportion of alkyl monoglycoside, the product also contains polyglycoside on polyglycose and butyl glucoside.
