摘要:
Disclosed is a novel granulation method, wherein a surface active foam obtained by foaming a flowable component that contains a surface active agent with a gaseous medium is used as granulation adjuvant. The surface active foam has an average pore size of less than 10 mm, preferably less than 5 mm, and especially less than 2 mm.

In order to obtain mechanically stable extrudates by using short-chain C8-C14-alkylsulfates when producing washing granulates by extrusion of a solid premix under high pressure, the short-chain alkylsulfates are used as a granulate produced in a fluidised bed and if required dried at the same time.

The invention concerns additives with an apparent density of 500 g/l for use in granular washing or cleaning agents with apparent densities of at least 500 g/l, said additives containing one or several anion surfactants and at least one other ingredient that is usually subsequently added when producing washing or cleaning agents, provided that this other ingredient or ingredients is an ingredient chosen from the following; bleach activator, bleach catalyst and premanufactured foam inhibitor. By adding these solid additives to solid base granules, the additives having approximately the same apparent density, granular form and size as the base granules, washing or cleaning agents with greater apparent densities are produced which have a uniform appearance and are not inclined to separate.

The present invention relates to a portioned washing agent and detergent composition contained in a bag made from a water-soluble film, whereby at least 70 wt. % of the particles of the washing agent and detergent composition consists of particles of more than 800 νm. The usual production-related sealing problems with respect to the seams of the bag and problems arising therefrom are avoided by selecting particles within said size range.
摘要:
The invention aims at providing particulate washing or cleaning agents, compounds or raw materials with apparent densities above 600 g/l for the latter which even with a reduced surface, in particular with a spherical shape disintegrate better when they are dissolved in an aqueous bath. Moreover, the particulate washing or cleaning agents, compounds or treated raw materials should be produced by joining washing or cleaning agent compounds and/or raw materials, at the same time as or after they are shaped. For that purpose, at first an essentially anhydrous premixture is produced, containing individual raw materials and/or compounds which are solid under standard conditions and have a melting or softening point not below 45 °C, as well as up to 10 wt % optional non-ionic surfactants which are liquid at temperatures below 45 °C and under 1 bar pressure. The mixture is granulated by applying compacting forces at temperatures of at least 45 °C, then further processed or conditioned; the premixture contains at least one raw material or compound which is solid under 1 bar pressure and at temperatures below 45 °C, but which melts under processing conditions, forming a molten mass which acts as a polyfunctional, water-soluble binder which serves as a lubricant during the production of the washing and cleaning agent and as an adhésive for the solid washing or cleaning agent compounds or raw materials, but which has a disintegrating effect when the washing or cleaning agent is dissolved again in an aqueous bath.

The aim of the invention is to improve the stability in storage of bleach activators of the quaternized amino alkyl nitrile type. To this end, the invention provides that a particle containing these bleach activators is enclosed in the most complete possible manner by an enclosing material.

The invention relates to a neutralization and granulation method. According to said method, a neutralizing foam is used as granulation adjuvant. Said neutralizing foam was previously obtained by mixing an anionic surfactant in its acid form, which was expanded using a gaseous medium, and a highly concentrated, aqueous alkaline component, which was expanded using a gaseous medium. The neutralizing foam has an average pore size of less than 10 mm, preferably less than 5 mm and especially less than 2 mm.
