Populations of benefit agent delivery particles are disclosed, the particles having a core and a shell encapsulating the core, the shell comprising certain multifunctional (meth)acrylate-based polymers, along with processes for making and uses of such compositions. The delivery particle has a core to polymer wall ratio by weight from about 96:4 to about 99.5 to 0.5 and a volume-weighted particle size from about 30 to about 50 microns. The compositions deliver core content with a desired delivery profile, such as fragrance delivery at desired touchpoints with higher efficiency. The delivery particle has high pay load, yet exhibits decreased benefit agent leakage, and provides a desired delivery profile.

Surfactants capable of releasing and/or dissolving polymers to form water-soluble or water-dispersible polymer solutions are disclosed. In addition, polymer compositions containing a water-in-oil emulsion comprising the surfactant are provided and can be used, for example, in methods of dissolving a polymer. Also disclosed are detergent compositions and methods of cleaning articles and/or membranes using the surfactants herein. These surfactants and polymer compositions can be used in various industries including for water clarification, papermaking, sewage and industrial water treatment, drilling mud stabilizers, and enhanced oil recovery.

Liquid fabric softener compositions containing (a) water-insoluble cationic softeners, (b) water-soluble cationic antibacterial agents and (c) cationic rheology modifying polymers are described that are stable homogenous mixtures. A method for determining stability of the softener formulations or determining the amount of component (a), (b) or (c) involves calculating a stability index of the formulation according to the following equation: Stability formula index=[(wt % of the (a) component+3*(wt % of the (c) component)]/[wt % of the (b) component], wherein a desirable stability index value is 2.5 or greater than 2.5.

The present invention relates to treatment compositions containing polymer systems that provide stability and benefit agent deposition as well as methods of making and using same. Such treatment compositions may be used for example as through the wash and/or through the rinse fabric enhancers as well as unit dose treatment compositions.
