Methods and compositions for stabilized, emulsified aqueous resin and/or polymer emulsions within aqueous fluids characterized by extreme chemical environment having high ionic strengths and/or extremes of pH are provided. The methods include combining an organic premix comprising an aqueous fluid and the emulsified aqueous resin/emulsion polymers with a high hydrophobic-lipophilic balance (HLB) surfactant and a fluid having an extreme chemical environment (e.g., an acidic passivate) to yield a composition wherein the emulsified aqueous resins are stabilized. Other methods include combining an emulsified aqueous resin/emulsion polymer with a high hydrophobic-lipophilic balance (HLB) surfactant and a fluid having an extreme chemical environment (e.g., an acidic passivate) to yield a composition wherein the emulsified aqueous resins are stabilized.
