Abstract: The present invention relates to the use of cycloaliphatic diamines as cosolvents for hydrophobic amines in aqueous solution. The cycloaliphatic diamines of the present invention have a formula: 1 where n is 1 or 2, each R is independently selected from a group consisting of: hydrogen, a 1 to 6 carbon aliphatic, and a 0 to 6 carbon containing amine, wherein each R is chosen such that the cosolvent amine comprises at least two amine groups; and a quantity of water to maintain said solution as a homogeneous phase. The cosolvent diatines have particular utility in the formation of water based epoxy resin curing agents. Superior water miscibility is achieved for hydrophobic amines through the use of cycloaliphatic amines as compared to conventional cosolvents.
