  • Publication number: 20240043688
    Abstract: Described herein stabilized polysiloxane particles and methods for making and using the same. In one aspect, the composite includes (a) a polysiloxane comprising one or more positively charged groups and a negatively charged polyelectrolyte polymer or (b) a polysiloxane comprising one or more negatively charged groups and a positively charged polyelectrolyte polymer. Additionally, components such as, for example, inorganic drying agent, a filler, a reinforcing agent, magnetic particles, a wet/dry indicator, a pharmaceutical agent, a catalyst, or any combination thereof. The composites are effective in encapsulating hydrophobic materials that can subsequently be dispersed in aqueous medium.
