Surfaces modified with polymeric or monomeric amic acids that comprise one or more tertiary amine functional groups are shown to be hydrophilic, resulting in enhanced oily soil repellency.  Using contact angle and bespoke soil release test methods, we demonstrate that the proposed amic acid candidates are effective at promoting oily soil release and are also substantive, water soluble, stable over a wide pH range, and compatible with ionic and nonionic surfactants.  Additionally, corrosion inhibition effects are demonstrated.  These characteristics make them attractive as additives for cleaning formulations. Due to their favorable economics and ease of production, these chemistries should prove useful in a number of formulations for both consumer and I&I formulations.
