1. A freeze-thaw stabilizer additive composition comprising (a) from 20 wt % to 80 wt %, based on the total weight of the freeze-thaw stabilizer additive composition, of at least one anti-freezing compound selected from the group consisting of glycerin alkoxylate, pentaerythritol alkoxylate, sorbitol alkoxylate, and mixtures thereof; and (b) from 20 wt % to 80 wt %, based on the total weight of the freeze-thaw stabilizer additive composition, of at least one emulsifier, wherein the at least one emulsifier comprises a C12 to C14 primary or secondary alkoxylate, castor oil ethoxylate, ethylene oxide/propylene oxide copolymer, butylene oxide, or a mixture thereof; wherein the freeze-thaw stabilizer additive composition provides a paint formulation having a stability such that the change in viscosity of the paint formulation is from 0 percent to less than 10 percent after the formulation is subjected to the Freeze-Thaw Stability Test described in GB/T-9168-2008, when the viscosity of the paint formulation is measured at 23° C. using a Stormer Viscometer before and after the Freeze-Thaw Stability Test.
