A method of resolving an emulsion that includes an oil phase and an aqueous phase comprising contacting said emulsion with an effective amount of a demulsifier composition comprising:
- 1) a C5-C7 alkyl phenol-formaldehyde resin alkoxylate and 2) a polyalkylene oxide triblock polyol surfactant wherein 1) is present in an amount of about 90-50% by weight based upon the combined weight of 1) and 2) said surfactant 2) being present in an amount of about 10-50% by weight based upon the combined weight of 1) and 2).
Demulsifier composition comprising:
- 1) a C5-C7 alkyl phenol-formaldehyde resin alkoxylate and 2) a polyalkylene oxide triblock polyol surfactant, said 1) and 2) being dispersed or dissolved in an organic solvent, said 1) being present in an amount of about 90-50% by weight based upon the combined weight of 1) and 2) and said 2) being present in an amount of about 10-50 wt % based upon the combined weight of 1) and 2).
