Abstract

This invention relates to organic acid corrosion inhibitors for use in antifreeze coolant compositions. The corrosion inhibitors comprise a C8 mono-carboxylic acid component, or isomers and/or salts thereof, and a neo-decanoic acid, or isomers and/or salts thereof. The corrosion inhibitors of this invention provide improved corrosion protection to metal surfaces as compared to conventional inhibitors and provide surprisingly improved corrosion protection as compared to inhibitors containing only a single mono-carboxylic acid component.
