Biodegradable chelating agents and methods for fabric care

Abstract

Biodegradable chelating agents comprising tropolone, derivatives of tropolone, and combinations and salts thereof can be incorporated into various fabric care compositions and delivery formats. A fabric care composition may comprise at least one component according to Formula 7, and combinations and salts thereof. (7) In Formula 7, R1 is a hydroxyl, C1-C6 carboxyl, linear or branched C1-C6 alkyl, linear or branched C2-C6 alkenyl, or linear or branched C2-C6 alkynyl group, a is 0-5, R2 is a condensed C1-C6 cycloalkyl, condensed C1-C6 cycloalkoxy, or condensed C1-C6 cycloalkenyl, b is 0-4, R3 is oxygen or hydroxyl, and c is 0-4.
