Definitions

  • 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.
  • Conventional fabric enhancer compositions typically comprise a solvent phase and particulates that comprise a fabric softener active. Such particulates may be vesicles.
  • a fabric enhancer composition may comprise other materials that include softener actives that are found in the fabric enhancer composition but outside the aforementioned particulates. Regardless of where such softener actives are found, it is desirable to increase the deposition efficiency of such softener actives as this can improve the performance of the fabric enhancer compositions and/or reduce the cost of such fabric enhancer compositions.
  • the deposition efficiency of fabric enhancer compositions is typically increased by the addition of deposition polymers. Unfortunately, as the level of deposition polymer in a fabric enhancer composition is increased the fabric enhancer composition's stability decreases. Eventually, as the level of deposition polymer is increased, the fabric enhancer composition's particulates will bulk separate, which manifests itself as phase separation or a change in the fabric enhancer composition's viscosity will occur, which results in the composition gelling.
  • the phase separation is driven by depletion induced flocculation due to excess deposition aid polymer in the solvent phase of the fabric enhancer composition and that gelling is due to the deposition aid polymer linking particulates.
  • the judicious selection of the type and level of the deposition polymer can lead to fabric enhancer compositions that exhibit improved fabric softener active deposition without exhibiting significantly increased stability negatives.
  • Such deposition polymers should have a high adsorption affinity for the aforementioned particulates - thus minimizing the amount of polymer in the fabric enhancer composition's solvent phase - and a low or no tendency to link particulates.
  • the formulator can use increased levels of such polymer and thus achieve the desired fabric softener active deposition without the aforementioned stability negatives.
  • This invention relates to fabric enhancer compositions 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 which may include poor silicone deposition, stringiness, and/or poor viscosity.
