Abstract:
A composition comprising a surfactant blend, comprising: a polyethylene glycol, wherein the polyethylene glycol has an average molecular weight of from 5,000 g/mol to 9,000 g/mol; a first ethoxylated alcohol comprising the formula R—O(EO)n—H, where R is an alkyl, alkenyl, aryl, aralkyl, or heterocyclic group having 7-25 carbons, where (EO) is a polyoxyethylene chain and where n is from 3 to 9, wherein the first ethoxylated alcohol has a Pour Point below 23° C.; and a second ethoxylated alcohol comprising the formula R—O(EO)m—H, where R is an alkyl, alkenyl, aryl, aralkyl, or heterocyclic group having 7-25 carbons, where (EO) is a polyoxyethylene chain and where m is from 12 to 20, wherein the second ethoxylated alcohol has a Pour Point at or above 23° C., further wherein the first ethoxylated alcohol is from 20 wt % to 80 wt % of a total weight of the surfactant blend.
