PROBLEM TO BE SOLVED: To use a crosslinked polyvinylpyrrolidone so as to increase the disintegration rate of a compact granulated detergent and cleanser when contacted with water, by utilizing crosslinked polyvinylpyrrolidone particles each with a specific diameter. SOLUTION: Crosslinked polyvinylpyrrolidone particles each with a diameter of 50-400 μm, preferably 80-300 μm are used as an additive so as to increase the disintegration rate of a compact granulated detergent and cleanser when contacted with water. The compact granulated detergent and cleanser mean particles exhibiting detergent and cleanser activities, especially pellets, e.g. (dishwasher) detergent pellets, bleaching agent pellets, or detergent pellets for clothing especially for domestic use, more especially in a washer. It is desirable that at least 10 wt.%, preferably 15 wt.%, more preferably 25 wt.% of the crosslinked polyvinylpyrrolidone particles have each a diameter of
Abstract:
The invention relates to the use of cross-linked polymers which have a water absorbency of less than 30 g/g polymer (determined in a 0.9 wt. % aqueous common-salt solution) and which contain polymerised monoethylenic unsaturated monomers that contain acid groups and/or the alkali salts or ammonium salts thereof and optionally additional polymerised monoethylenic unsaturated monomers. Said cross-linked polymers are used as an additive for compact, particle-shaped washing and cleaning agents for increasing the disintegration rate when being brought into contact with water. The invention also relates to the use of compact, particle-shaped washing and cleaning agents which contain cross-linked polymers with a water absorbency of less than 30 g/g polymer (determined in a 0.9 wt. % aqueous common-salt solution).
Abstract:
The invention relates to a method for the production of formic acid formates, wherein a flowing liquid (I) containing formic acid, and a flowing liquid (II) containing a metal formate, are provided. The flowing liquids (I) and (II) are guided to a rectification column such that a higher or equal guiding point for the liquid flow (II) is selected for the rectification column for the liquid flow (I). The liquid flows (I) and (II) in the rectification column are mixed by separating water via the head of the rectification column and the liquid flow is withdrawn from the rectification column, said liquid flow containing the formic acid formate. The invention is characterised in that the liquid flow is obtained as a melt containing at least 0.5 wt. % water.
Abstract:
A process is proposed for preparing acid formates in which a liquid stream I comprising formic acid and a liquid stream II comprising a metal formate are prepared, the liquid streams I and II are fed to a rectification column in such a manner that a higher or identical feed point to the rectification column is chosen for the liquid stream II than for the liquid stream I, the liquid streams I and II are mixed in the rectification column, with water being removed overhead from the rectification column and a bottoms stream comprising the acid formate is taken off from the rectification column, which comprises the bottoms stream being produced as melt comprising less than 0.5% by weight of water.
Abstract:
The invention relates to a method for producing and using a solid sodium diformate having a high formic acid content, to the use thereof in animal foods in the form of an acidifier, preservatives, ensilage auxiliary agents, fertilisers and a growth- and productivity-stimulating agent and the inventi ve animal food additives containing sodium diformate.
Abstract:
Dry microorganism cultures comprising at least one microorganism species in carrier-bound form are present in the form of particles which a) have a particle size of at least about 0.1 mm and b) are compressed; processes for preparing dry microorganism cultures and their use for preparing foodstuffs and feedstuffs are also claimed.
Abstract:
A method for preparing formic acid formates (A) comprises supplying separate liquid streams of formic acid (stream I) and a metal formate (stream II) to a rectification column, with II supplied at the same height as I, or at a higher position. Water is separated as overhead and an (A)-containing sump product is recovered. The sump product is recovered as a melt containing less than 0.5 wt.% water.
Abstract:
Granular materials are obtainable by pressing mixtures of at least one pulverulent, rheology-modifying, carboxyl-containing polymer as main component and at least one oil-soluble component.
