Silica microcapsules and methods of preparing same

Abstract:

Disclosed is a microcapsule containing: (i) a microcapsule core having an active material, and (ii) a microcapsule wall formed of a first polymer and second polymer. The first polymer is a sol-gel polymer. The second polymer is gum arabic, purity gum ultra, gelatin, chitosan, xanthan gum, plant gum, carboxymethyl cellulose, sodium carboxymethyl guar gum, or a combination thereof. The weight ratio between the first and second polymer is 1:10 to 10:1. Also disclosed are processes for preparing the microcapsule and uses of the microcapsules in consumer products.
