Abstract: A system includes an anti-allergen formulation and a device that generates droplets of the formulation to be delivered to an air environment. The aqueous formulation includes an organic acid having a vapor pressure between 0.001 Pa and 172 Pa and an aqueous solubility of at least 24.99 grams organic acid per 100 grams water, both at room temperature and standard pressure. The device can generate droplets of the formulation having a median particle size (Dv50) of no greater than 120 micrometers. The formulation delivered as droplets in an air environment can provide a statistically significant reduction, over a control, in one or more airborne allergens as measured by an enzyme linked immunoassay. In addition, the formulation delivered as droplets in the air environment can be effective to neutralize greater than 50% of one or more airborne allergens present in the air environment.

Abstract: A toner process comprised of a first heating of a mixture of an acicular magnetite dispersion, a colorant dispersion, a wax dispersion, and a core latex comprised of a first latex containing a vinyl crystalline polyester resin substantially free of crosslinking, and wherein said polyester is substantially dissolved in a vinyl monomer and polymerized to provide said first core latex resin, and which mixture contains a second crosslinked resin containing latex wherein said heating is accomplished in the presence of a coagulant to provide aggregates; adding a shell latex comprised of a polymer substantially free of crosslinking, and further heating said aggregates to provide coalesced toner particles, and wherein said further heating is at a higher temperature than said first heating.

Abstract: A toner composition is provider including a branched amorphous polyester resin and a crystalline polyester resin, wherein the toner possesses rheological properties yielding desired characteristics.

Abstract: A process for preparing toner particles and compositions adapted for use in preparing toners that comprise a blend of a first polyester resin with a second sharp melting polyester resin. The process includes forming an emulsion resin comprising a branched polyester resin, a crystalline polyester resin, a colorant, and optionally a wax. The resin mixture is aggregated using an aggregating agent, such as a zinc acetate solution, to form an aggregate mixture. The aggregate mixture is then coalesced at a temperature of from about 5 to about 20° C. above the Tg of the emulsion resin to produce the resultant toner particles.

Abstract: A toner containing a mixture of a sulfopolyester resin, a colorant and an alkyl amide.
