Patent

CA 2316115

There is provided according to the present invention an aqueous gel composition, comprising a) an ethoxylated polyhydric alcohol which comprises a reaction product of an alcohol having 3 to 6 hydroxy groups with ethylene oxide; and b) a gelling agent selected from the group consisting of a polyoxyethylene/polyoxypropylene/polyoxyethylene triblock surfactant having a molecular weight of from 4,000 to 16,000, and wherein the weight of the polyoxyethylene blocks is from 55% to 90% of the weight of the triblock surfactant; a crosslinked polyacrylic thickener; cellulose derivatives; hydrated silicas; and mixtures thereof. When the gelling agent is the triblock surfactants, the ethoxylated polyhydric alcohol comprises the reaction product of the polyhydric alcohol and up to 5 mole equivalents of ethylene oxide per mole equivalent of hydroxyl group in the alcohol.
