Abstract: The disclosure relates generally to the detergent art and more specifically to a silicic acid detergent product for the microdeposition of silicic acid on textiles. The product comprises essentially an adduct (hydrogen bond compound) of oligomer and/or polymer silicic acid with polyethylene oxide compounds together with alkali, M.sub.2 O, where M is selected from the group consisting of Na, K, Li, alkanolamines and a quaternary ammonium group, amounting to a molar ratio SiO.sub.2 :M.sub.2 O>4, or preferably 6-100, said product being physically or colloidally soluble in laundry medium inside a pH of 8-12, in which medium it serves as a microdepositor for silicic acid on laundry textiles.
