Abstract

This invention relates to fabric enhancer compositions comprising a hydrophobically modified cationic polymer that comprises a hemicellulose backbone or a starch backbone as well processes of making and using same. Such compositions exhibit improved fabric softener active deposition without exhibiting significantly increased stability negatives such as creaming/phase separation.
