A method for improving the corrosion resistance of aerosol or foam hair spray formulations in metal containers is disclosed. In particular, the present invention involves the use of phosphate ester emulsifiers in the preparation of the emulsion polymer hair fixative resins to provide corrosion resistance of the hair styling composition in metal containers without negatively affecting the performance of the hair styling product itself. Use of the selected emulsifiers is particularly useful in non-corrosive aqueous hair styling compositions containing low (80% or less) volatile organic compound (VOC) concentrations.
