摘要:
An active agent delivery dispersion includes water, 1 to 98 weight percent of a plurality of encapsulated particles dispersed in the water, and 0.1 to 20 weight percent of an active agent, each based on a total weight of the dispersion. The active agent is dispersed in the water independently from the plurality of encapsulated particles. Each of the particles includes a core and a layer including a silica disposed about the core. The plurality includes first and second populations of encapsulated particles. The core of the first population includes a first organopolysiloxane having at least two silicon-bonded alkenyl groups per molecule and a hydro-silylation catalyst. The core of the second population includes an organohydrogensiloxane having an average of greater than two silicon bonded hydrogen atoms per molecule and a second organopolysiloxane having at least two silicon-bonded alkenyl groups per molecule.
