Abstract

FIELD: production of highly dispersion anion loose surface active substances for washing and / or clearing. SUBSTANCE: 1. Highly dispersion anion loose surface active substances for washing and / or clearing has microporous structure without dust forming shares. In the case its loose density is minimum 150 g/l and its share of residual water is maximum 20 weight %. 2. Highly dispersion loose composition has at least one anion surface active substance and at least one organic and / or inorganic auxiliary and / or useful substance. As anion surface active substance it has anion surface active substance of microporous structure without dust forming shares and its components are taken in following amount ratio (weight %): anion surface active substance 35 -95; organic and / or inorganic auxiliary and / or useful substance balance. In the case anion surface active substance has loose density at least 150 g/l and share of residual water in it is at least 20 weight %. 3. Method to produce highly dispersion anion loose surface active substances or their mixtures at least with one organic and / or inorganic auxiliary and / or useful substance provides for: feeding of water preparation of the substances or their mixture in stream, that has water steam of drying medium; discharge of highly dispersion solid loose product, removal of stream of waste drying medium, separation of stream bearing particles of useful substances, recirculation of purified drying medium part into process. As drying medium they use overheated steam, that after initial separation from it of evaporated from raw material water share, is fed in process for recirculation. EFFECT: improved process. + ++

Claims (1)

The object of the invention is a finely divided granular anionic surfactant for detergents and / or cleaning agents, which has a microporous structure without dust-forming parts, and its bulk density is at least 150 g / l, and its residual water content is a maximum of 20 wt.%. Another object of the invention is a finely divided loose detergent and / or cleaning composition containing at least one anionic surfactant and at least one organic and / or inorganic auxiliary and / or useful substance, and as an anionic surfactant it contains an anionic surfactant of a microporous structure without dust-forming fractions, and the components are taken in the following quantitative ratio, wt.%: anionic surfactant the substance 35 - 95, the organic and / or inorganic excipient and / or useful substance - the rest, while the anionic surfactant has a bulk density of at least 150 g / l, and the content of residual water in it is a maximum of 20 wt.% . A further object of the invention is a method for producing highly dispersed free-flowing anionic surfactants or mixtures thereof with at least one organic and / or inorganic auxiliary and / or useful substance by supplying an aqueous preparation of these substances or their mixture to a stream of drying medium containing water vapor the release of a finely divided solid granular product, the removal of the flow of spent drying medium, the separation of particles of useful substances and the recycling of part of the purified drying medium into the process, Rich as the drying medium is superheated steam which, after preliminary separation from it the vaporized fraction from the raw water is recycled into the process.
