| 摘要 |
The present invention is method of boosting the performance of a cost-reduced liquid fabric softener comprising a quaternary surfactant fabric softener by adding a quaternary (meth)acrylic polymer that functions dually as a fabric softening active and a rheology modifier. In particular, poly[{2-(methacryloyloxy)ethyl} trimethylammonium chloride], poly[{2-(acryloyloxy)ethyl} trimethylammonium chloride], poly[{3-(methacryloyloxy)propyl} trimethylammonium chloride], and poly[{3-(acryloyloxy)propyl} trimethylammonium chloride] provide synergistic fabric softening with quaternary surfactants to provide superior fabric softening scores from cost-optimized compositions. |
