Abstract
Abstract Compositions of matter useful in the manufacture of superior cleaning and fabric treating compositions, bleaches, and the like, comprise amino-silane compounds in combination with ingredients such as cationic fabric softeners, or detersive surfactants, or bleach or the like. Such compositions are especially useful in aqueous fabric laundering baths and in combined fabric drying/ softening operations since the amino-silane provides a protective effect to the surface of the washing machine or dryer. The compositions are also useful in the formulation of porcelain-safe toilet cleansers, machine- and hand- dishwashing compositions that protect fine chinaware, and for similar uses wherein silicate or metal surfaces come in contact with harsh chemicals, especially in the presence of hot water.
