Fabric treating compositions containing esterquat with periodate salts

Abstract

Dispersible aqueous textile treatment compositions, such as fabric softeners, which include biodegradable quaternary ammonium fabric softener actives, and which exhibit excellent long-term storage stability, even where the storage is at elevated temperatures over long periods of time. The compositions comprise a biodegradable, fatty ester quaternary ammonium compound derived from the reaction of an alkanol amine and a fatty acid derivative, followed by quaternization; together with a periodate salt, such as potassium periodate.

Description

[0001] Cross References to Related Patents [0002] This application claims priority to US Provisional Patent Application No. 60 / 798,256, filed May 5, 2006, which is hereby incorporated by reference in its entirety. Background technique [0003] In laundry cleaning operations, compositions containing quaternary ammonium salts or imidazolinium salt compounds having at least one long chain hydrocarbyl group are commonly used to provide fabric treatment properties, especially good fabric softness. [0004] Recently, due to problems caused by the environmental safety (such as biodegradability) of quaternary compound softeners, and the limitation of the amount of cationic compounds that can be stably combined into more convenient liquid formulations, partial or complete replacement of traditional softeners has been proposed. Examples of alternatives to "quaternary ammonium" fabric softeners are dimethyl distearyl ammonium chloride or dimethyl ditallow ammonium chloride and various ...

Problems solved by technology

[0005] While it is recognized that there is a need to have fabric softener materials containing biodegradable linkages in textile treatment compositions, it is also recognized that these materials present difficulties with unpredictable or uncontrollable stability in long-term storage, especially in under high temperature
