FABRIC SOFTENING AGENTS AND COMPOSITIONS THEREOF

摘要

This invention relates to a non-stoichiometric bisimidazoline ion pair complex. The ion pair complex comprises a bisimidazoline, organic acids selected from alkyl and aryl carboxylic acids, alkyl and alkyl aryl sulfonic acids, and alkyl dicarboxylic acids, and Bronstedt acids. The ion pair complex thus obtained can be concentrated and still retain softening performance benefits over many known conventional softeners. The ion pair complex can be combined with cosofteners in an aqueous fabric softening composition used to treat fabrics, usually during the rinse cycle of laundering operations.
