Title: METHOD FOR PRODUCING GRANULATES WITH A LONG SHELF LIFE CONTAINING SOIL RELEASE POLYMERS AND THE USE THEREOF FOR THE PRODUCTION OF SOLID DETERGENTS AND CLEANING AGENTS
Abstract:
The invention relates to a method for the production of granulates, consisting chiefly of a soil release polymer, a fine-particled, absorbing, high-melt substrate and a coating material. In a first step of the inventive method, the soil release polymer is deposited on the substrate. In a second step, the primary granulate thus obtained is sprayed with a coating material to form a film. The invention also relates to the granulates thus obtained, to the use of said granulates in solid detergents and cleaning agents and to solid detergents and cleaning agents which contain granulates produced according to the inventive method.
