ABSTRACT:
This invention relates to a method and composition for inhibiting discoloration of the emulsions due to contact with ferrous materials. The invention comprises adding from 0.1 to 1.6 wt. %, preferably, from 0.3 to 0.9 wt. % based on the oil phase of the emulsion of one or more members of the group consisting of phosphoric acid and disodium phosphate. The invention also optionally comprises an amount of pit corrosion inhibitor selected from the group consisting of zinc pyrithione and a zinc containing siloxane resin. The invention also includes the composition of a silicone polymer in water emulsion, wherein the emulsion contains form 0.1 to 1.6 wt%, preferably, from 0.3 to 0.9 wt. % based on the oil phase of the emulsion of one or more mebers of the group consisting of phosphoric acid and disodium phosphate and optionally comprises an amount of pit corrosion inhibitor.
