The present invention relates to a specific type of phosphate ester that is as effective or more effective than corrosion inhibitors available in the past. In accordance with the invention, these corrosion inhibitors are highly effective alone or when blended with other specific compounds for protection of ferrous metals against attack by a corrosive environment. More particularly, the inhibitors of the present invention are the reaction products of ethoxylated, propoxylated, or butoxylated alcohols or phenols with phosphating agents.
