Flexible wax and method of making same

A method of making a flexible wax composition, comprising:

• mixing fatty acid and/or oil, a fatty acid dimer, and glycerin to form a mixture;
• and
• adding a caustic or enzymatic catalyst to the mixture to facilitate esterification and transesterification reactions until the mixture achieves an acid value of less than 1.5, so as to obtain a flexible wax composition, the flexible wax composition comprising
• about 20 wt % to about 45 wt % monoacylglycerides,
• about 28 wt % to about 40 wt % diacylglycerides, and
• about 10 wt % to about 45 wt % acylglyceride polymers, wherein the acylglyceride polymers are compounds containing the one or more dimerized fatty acid residues and a plurality of glycerol moieties;
• wherein the flexible wax composition has an average creep stiffness of less than about 30 Mpa.
