ABSTRACT:
A non-caking and freely flowing granulated composition of high abrasion resistance, said composition containing a polymer phosphate and an ion exchanging alkali metal aluminum silicate is provided. At least part of the polymer phosphate in said composition is a highly condensed phosphate, preferably of a phosphorus pentoxide content between about 64% and about 69%. Said composition 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 of a highly condensed phosphate and an alkali metal aluminum silicate to which sodium tripolyphosphate and a tenside may be added, comprises granulation of the mixture of polymer phosphate and alkali metal aluminum silicate by spraying water or a tenside solution thereon. Preferred tensides are ethoxylated nonylphenols. Other agents are conventionally added to the resulting compositions. The resulting granulated compositions have proved to be useful as additives to washing, rinsing, and cleaning agents, as water softening agents, as textile washing agents, and the like.
