Process for preparing spray dried blended detergents
Abstract
Abstract IMPROVED DETERGENT COMPOSITIONS ARE PREPARED BY ADDITION OF A PORTION OF THE TOTAL FORMULATION TO THE REMAINDER OF THE INGREDIENTS AFTER THESE HAVE BEEN SPRAY DRIED. SPECIFICALLY IT HAS BEEN FOUND THAT BLENDING COMPOSITES OF HYDRATED ALKALI METAL SILICATE GLASS AND SEQUESTERING AGENTS WITH THE SPRAY DRIED GRANULES OF THE OTHER DETERGENT INGRIEDENTS YIELD FORMULATIONS WITH IMPROVED PROPERTIES. COMPARED WITH CONVENTIONAL SPRAY DRYING OF COMPLETE DETERGENT COMPOSITIONS, THIS PROCESS ALLOWS MORE UNIFORM DISTRIBUTION OF MINOR COMPONENTS THROUGHOUT THE FORMULATION, HIGHER ALKALI METAL SILICATE LEVELS, AND DECREASES OR EVEN ELIMINATES THE FORMATION OF INSOLUBLES. AN ADDITIONAL ADVANTAGE OF THIS PROCESS IS THAT IT PERMITS INCREASED PRODUCTION RATES.
