Abstract

The present application relates to encapsulated benefit agents, compositions comprising such encapsulated benefit agents and processes for making and using compositions comprising such encapsulated benefit agents that do not require or require a reduced amount of scavenger materials. Such encapsulated benefit agents, compositions comprising such encapsulated benefit agents are processed such that no or lower levels of scavenger materials are required.

First claim

What is claimed is:

1. A consumer product comprising an adjunct material and, based on total composition weight, from about 0.1% to about 20% of a benefit agent delivery composition comprising, based on total benefit agent delivery composition weight:
a.) from about 2% to about 95% of an encapsulated benefit agent, said encapsulated benefit agent optionally comprising a sufficient amount of benefit agent to provide, based on total benefit delivery composition weight from about 1% to about 85% benefit agent;
b.) from about 1% to about 12% shell particles; and
c.) the balance of said benefit agent delivery composition being one or more processing aids and/or carriers.

2. The consumer product of claim 1 , wherein said encapsulated benefit agent comprises, a benefit agent selected from the group consisting of perfumes; brighteners; insect repellants; silicones; waxes; flavors; vitamins; fabric softening agents; skin care agents; enzymes; anti-bacterial agents; bleaches; and mixtures thereof.

3. The consumer product of claim 1 , wherein said shell particles comprise an amino resin.

4. The consumer product of claim 2 , wherein said encapsulated benefit agent's perfume comprises a perfume raw material selected from the group consisting of Quadrant I, II, III perfume raw materials and mixtures thereof.

5. The consumer product of claim 1 , wherein said benefit agent delivery composition's one or more processing aids are selected from the group consisting of water, aggregate inhibiting materials such as divalent salts, soil suspending polymers, and mixtures thereof.

6. The consumer product of claim 1 , wherein said benefit agent delivery composition's one or more carriers is selected from the group consisting of polar solvents; nonpolar solvents, and mixtures thereof.

7. The consumer product of claim 2 , wherein:
a. said encapsulated benefit agent's perfume comprises a perfume raw material selected from the group consisting of Quadrant I, II, III perfume raw materials and mixtures thereof;
b. said benefit agent delivery composition's one or more processing aids are selected from the group consisting of water, aggregate inhibiting materials and mixtures thereof; and
c. said benefit agent delivery composition's one or more carriers is selected from the group consisting of water, ethylene glycol, propylene glycol, polyethylene glycol, glycerol; nonpolar solvents, and mixtures thereof.

8. The consumer product of claim 1 , wherein said consumer product adjunct is selected from the group consisting of polymers, for example cationic polymers, surfactants, builders, chelating agents, dye transfer inhibiting agents, dispersants, enzymes, and enzyme stabilizers, catalytic materials, bleach activators, polymeric dispersing agents, clay soil removal/anti-redeposition agents, brighteners, suds suppressors, dyes, additional perfume and perfume delivery systems, structure elasticizing agents, fabric softeners, carriers, hydrotropes, processing aids and/or pigments and mixtures thereof.

9. A consumer product according to claim 1 , comprising a material selected from the group consisting of dyes; perfume; optical brighteners; deposition aids; and mixtures thereof.

10. A method of treating and/or cleaning a situs, said method comprising
a.) optionally washing and/or rinsing said situs;
b.) contacting said situs with a consumer product according to claim 1 and
c.) optionally washing and/or rinsing said situs.

11. A consumer product comprising an adjunct material and, based on total composition weight, from about 0.1% to about 20% of a benefit agent delivery composition comprising, based on total benefit agent delivery composition weight:
a.) from about 2% to about 95% of an encapsulated benefit agent, said encapsulated benefit agent optionally comprising a sufficient amount of benefit agent to provide, based on total benefit delivery composition weight from about 1% to about 85% benefit agent;
b.) from about 0.1% to about 5% shell particles; and
c.) the balance of said benefit agent delivery composition being one or more processing aids and/or carriers.

12. A consumer product according to claim 11 , comprising, based on total consumer product weight:
a.) from about 0.1% to about 5%, encapsulated benefit agent, said benefit agent comprising an amino resin;
b.) from about 1 ppm to about 150 ppm, formaldehyde; and
c.) less than about 0.3 weight %, formaldehyde scavenger.
