Release agent and corrosion inhibitor formulation and method of use

A release agent and corrosion inhibitor formulation that yields minimal film buildup comprising:

• at least one tertiary ethoxylated fatty amine having formula (I)
• wherein R′=C8-C20 linear or branched, saturated or unsaturated aliphatic group, and subscripts j+k=2-20 moles of ethylene oxide content on average, and
• at least one of an acidic alkyl phosphate ester and an acidic phosphate ester ethoxylate, or combinations thereof, having formula (II)
• wherein X=C6-C14 aliphatic carbon chain (either linear or branched) and Y=H or C6-C14 aliphatic carbon chain (either linear or branched) for the acidic alkyl phosphate ester;
• and
• wherein X=—(CH2CH2O)z—R where R=a C6-C20 aliphatic carbon chain (linear or branched;
• saturated or unsaturated) and z=2-10 units of ethylene oxide content and Y=H or —(CH2CH2O)z—R where R=a C6-C20 aliphatic carbon chain (linear or branched;
• saturated or unsaturated) and z=2-10 units of ethylene oxide content, for the acidic phosphate ester ethoxylate;
• and
• water;
• wherein an active basis weight ratio of the at least one of an acidic alkyl phosphate ester and an acidic phosphate ester ethoxylate or combination thereof to the at least one tertiary ethoxylated fatty amine ranges between about 5/95 to about 60/40;
• and
• wherein a total actives content of the formulation ranges between about 5 and about 50% by weight of the total formulation, the balance being water.
