Abstract
Official abstract text for this publication.
This invention relates to a method for emulsion templating hollow silica-based particles. The particles are suitable for containing one or more active ingredients or for containing other smaller particles which may include one or more active ingredients. The emulsion templated particles can be formed from two or more silanes. The emulsion templated particles can also be formed from a silane and a compound that attaches a polymer on the shell of the hollow silica-based particles.
First claim
Opening claim text (preview).
What is claimed is: 1. A method for forming silica-based particles, the method comprising the steps: (a) preparing an emulsion having a basic pH, the emulsion including a continuous phase that is polar and has one or more cationic surfactants, and a dispersed phase comprising droplets including a non-polar active ingredient and a non-polar diluent; (b) adding a first modified silica precursor to the emulsion such that the first modified silica precursor is emulsion templated ont…
