13 . The softened product of claim 1 , wherein the amine epoxide adduct is a multiple charged anionic compound having 1, 2, 3, or more negative charges.
14 . The softened product of claim 1 , wherein the amine epoxide adduct compound comprises an epoxide consisting of a monoepoxide or a polyepoxide.
15 . The softened product of claim 1 , the amine epoxide adduct has a hydrophobicity and/or hydrophilicity and the alkyl groups and alkyl have a length of carbon chains, and wherein the length of the carbon chains and/or the amount of epoxides adjusts the hydrophobicity and/or hydrophilicity of the amine epoxide adduct.
16 . The softened product of claim 1 , wherein the amine used to generate the amine epoxide adduct compound is selected from pentaethylenehexamine, tetraethylenepentamine, diethylenetriamine, ethyleneamine E-100, triethylenetetramine, tris(2-aminoethyl)amine, or a combination thereof.
17 .
