Abstract
A non-caking and freely flowing granulated composition of high abrasion-resistance which comprises a polymer phosphate and an ion-exchanging alkali metal aluminum silicate is disclosed. At least part of the polymer phosphate in said composition is a highly condensed phosphate, preferably of a phosphorous pentoxide-content between about 64% and about 69%. Said polymer phosphate may contain sodium tripolyphosphate in an amount between about 95% and 0% by weight and preferably between 80% and 60% by weight. Such a composition may also contain a water-soluble tenside which is liquid at room temperature. The process of producing such a granulated composition comprising a highly condensed phosphate and an alkali metal aluminum silicate, comprises granulation of the mixture of polymer phosphate and alkali metal aluminum silicate by spraying water or a tenside solution thereon. The resulting granulated composition is useful as additive to washing, rinsing, and cleaning-agents, as water-softening agents, as textile-washing agents, and the like.
