Abstract:
1. A cleaning composition comprising: a) a primary detergent component which comprises at least one non-ionic surfactant having a critical packing parameter of ≧0.95, b) silanized colloidal silica particles wherein at least about 40 wt % of the colloidal silica particles are silanized, and c) a secondary surfactant having a critical packing parameter of <0.85, wherein said primary detergent component is an alkoxylate surfactant having the formula and wherein R 1 is linear or branched, saturated or unsaturated hydrocarbyl group containing from 8 to 18 carbon atoms, AO is an alkyleneoxy group, and n is an integer from 1 to 25; and wherein said secondary surfactant is selected from I.) an alkyl (poly)glucoside having the formula R G is a monosaccharide residue; p is a real number from 1 to 5; II.) an amine oxide of the structure wherein R is a alkyl group containing 10-18 carbons optionally containing an amide or ester linkage, R1 and R2 can be the same or different and are selected from the group consisting of, methyl, ethyl, hydroxyl ethyl, 2-hydroxy propyl; III.) a cationic surfactants is of the formula where R=C 6 -C 22 hydrocarbyl, R 1 and R 2 are independently C 1 -C 4 alkyl, n is at least 12, and X − is an anion; IV.) a surfactant of the formula where R=C 6 -C 22 hydrocarbyl, R 1 is independently C 1 -C 4 alkyl, n is an integer of from 12 to 17; and X is an anion; V.) an amphoteric secondary surfactant of the formula where R=C 6 -C 22 hydrocarbyl having 6 to 22 carbon atoms, n is an integer of from 1 to 4 VI.) a nonionic surfactant comprising a C
