Abstract
The present invention relates to an aqueous composition comprising three components. The first component is a primary detergent, non-ionic surfactant with a critical packing parameters (CPP) of ≧0.95. The second component is a inorganic particle whose surface has been modified to improve stability. The third necessary component is a secondary surfactant with a CPP of ≦0.85. The secondary surfactant can function to improve the overall cleaning performance, the streaking performance and provide overall formulation stability.
