ABSTRACT:
Disclosed is a process for inhibiting the formation of discoloration in an aqueous composition selected from the group consisting of water-based paint, adhesive, caulk and sealant compositions, and combinations thereof, wherein said discoloration is caused by the presence of ferric ion or cupric ion together with pyrithione in said composition. The process comprises contacting the composition with a discoloration-inhibiting amount of a zinc compound selected from the group consisting of zinc salts of organic acids, zinc salts of inorganic acids, zinc hydroxide, zinc oxide, and combinations thereof. Also disclosed is an aqueous antimicrobial composition protected against discoloration attributable to the presence of ferric ion or cupric ion therein.
