Abstract: An antistatic composition is provided for improving the conductivity of a wide variety of substrates. The composition comprises an aqueous solution containing(a) an anionic organic phosphate surfactant of the formula ##STR1## wherein R.sub.1 is selected from the group consisting of ##STR2## wherein --(R.sub.2)-- is selected from the group consisting of branched and linear alkylene having 4 to 18 carbon atoms, and wherin R.sub.3 and R.sub.4 are the same or different and are selected from the group consisting of hydrogen and branched and linear alkyl of 4 to 12 carbon atoms,and wherein n.sub.1 is an integer of 4 to 14, and(b) disodium phosphate, wherein the weight ratio of ingredient (a) to ingredient (b) is from about 1:20 to about 20:1.

Abstract: A process for neutralizing a static electric charge on a surface consists essentially of contacting an atmosphere with at least one aqueous static charge composition by spraying an effective amount of the composition into the atmosphere, and then contacting the resulting treated atmosphere with a surface having static electric charge thereon to thereby neutralize at least a portion of the charge. The static charge composition is prepared from substantially deionized water to thereby increase the rate at which the static charge is neutralized.
Abstract: A method for simultaneously neutralizing positive and negative static electric charges on surfaces consisting essentially of contacting a first atmosphere with a positive static charge composition (108) by spraying (125) an effective amount of the composition into the atmosphere, contacting a second atmosphere with a negative static charge composition (8) by spraying (25) an effective amount of the negative static charge composition into the second atmosphere, mixing (126) the resulting treated first atmosphere with the resulting treated second atmosphere to thereby form a mixed atmosphere, and contacting at least one surface (16) having positive and negative static electric charges thereon with the mixed atmosphere to thereby simultaneously neutralize positive and negative static charges on the surface.

Abstract: A process for imparting a positive electrical charge to a gaseous stream comprises contacting the stream with an aqueous solution comprising about 500-3000 ppm of a composition consisting essentially of borax and a surfactant. In the composition, borax and the surfactant are present in a weight ratio of borax to surfactant of about 1.2:1 to about 15:1. The process and composition are useful in the control of static electricity.
