Abstract
Abstract A detergent composition containing an anionic detergent and an organosilane is capable of imparting soil release benefits to hard surfaces washed therewith. Soil adheres to such surfaces less strongly thereby making them easier to clean. The detergent composition can be formulated for use in a wide range of applications, e.g., as a light duty liquid composition, car wash composition, oven cleaner, window cleaner or toilet bowl cleaner.
