Processes for preparing multiple capsules

A method of preparing a capsule delivery system having two different capsules, the method comprising:

• (a) providing a first emulsion containing a first benefit agent and a first capsule wall-forming material;
• (b) providing a second emulsion containing a second benefit agent and a second capsule wall-forming material;
• (c) mixing the first emulsion and the second emulsion to obtain an emulsion mixture;
• (d) causing the formation of a first capsule and a second capsule to obtain a mixed capsule slurry, the first capsule containing the first benefit agent encapsulated by a first capsule wall formed of the first capsule wall-forming material, the second capsule containing the second benefit agent encapsulated by a second capsule wall formed of the second capsule wall-forming material, and the first capsule being different from the second capsule;
• and
• (e) curing the mixed capsule slurry to obtain the capsule delivery system,
• wherein the first or second benefit agent, independently, is a fragrance, flavor, malodor counteracting agent, or combination thereof.

A method of preparing a capsule delivery system containing two different capsules, the method comprising:

• (a) providing a first capsule slurry including a first capsule, in which the first capsule contains a first benefit agent encapsulated by a first capsule wall that is formed of a first wall-forming material;
• (b) providing a second emulsion including a second benefit agent and a second wall-forming material;
• (c) mixing the first capsule slurry and the second emulsion to obtain a capsule mixture;
• (d) causing the formation of a second capsule to obtain a mixed capsule slurry, in which the second capsule contains the second benefit agent encapsulated by a second capsule wall, the second capsule wall is formed of the second wall-forming material, and the second capsule is different from the first capsule;
• and
• (e) curing the mixed capsule slurry to obtain the capsule delivery system,
• wherein the first or second benefit agent, independently, is a fragrance, flavor, malodor counteracting agent, or combination thereof.

A method of preparing a capsule delivery system containing two different capsules, the method comprising:

• (a) providing a first capsule emulsion including a first water phase, a first wall-forming material, and a first core material, in which the first core material has a first benefit agent and is dispersed in the first capsule emulsion as oil droplets having a size of 0.01 to 1000 microns;
• (b) adding a second core material and a second wall-forming material to the first capsule emulsion, in which the second core material has a second benefit agent;
• (c) emulsifying the second core material to obtain a second capsule emulsion, in which the second core material is dispersed in the second capsule emulsion as oil droplets having a size of 0.01 to 1000 microns;
• (d) causing the formation of a first and second capsules to obtain a mixed capsule slurry, in which the first capsule is different from the second capsule, the first capsule contains the first benefit agent encapsulated by a first capsule wall, the first capsule wall is formed of the first wall-forming material, the second capsule contains the second benefit agent encapsulated by a second capsule wall, the second capsule wall is formed of the second wall-forming material;
• and
• (e) curing the mixed capsule slurry to obtain the capsule delivery system,
• wherein the first or second benefit agent is a fragrance, flavor, malodor counteracting agent, or combination thereof.
