摘要： 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.

摘要： A system and method for printing and drying flavors and fragrances is provided. The system and method include a source of flavor or fragrance, a print assembly adapted to print the flavor or fragrance, a movable product conveyor that directly receives the printed flavor or fragrance and a drying component. As the movable product conveyor passes through or adjacent to the drying component, the printed flavor or fragrance is dried thereby providing a free-flowing flavor or fragrance product.

摘要： Poiyurea or polyurethane capsule compositions. A subset of these compositions contain a plurality of capsules and a capsule formation aid, in which each of the capsules contains a poiyurea or polyurethane wall and an oil core; the poiyurea or polyurethane wall is formed of a reaction product of a polyisocyanate and a cross-linking agent in the presence of the capsule formation aid; and the oil core contains an active material. The polyisocyante, cross-linking agent, and capsule formation aids are described herein. Also disclosed are methods of preparing poiyurea and polyurethane capsule compositions, as well as consumer products containing one of these compositions.
