Abstract

Compositions, articles and methods are provided for supplying fabric care benefits to clothing or fabrics in an automated washing machine and by manual washing. The fabric care compositions preferably have less than about 5% detergent surfactants, more preferably less than 3%, even more preferably less than 1% and are most preferably free of detergent surfactants. Similarly, the fabric care compositions preferably have less than about 5% fabric softener actives, more preferably less than 3%, even more preferably less than 1% and are most preferably free of detergent surfactants. The laundry articles can take a variety of forms in a variety of physical states all of which will rapidly dispense a unitized amount of one or more selected fabric care agents to a wash and/or rinse bath solution during the laundering process under a variety of conditions. The invention also pertains to laundry kits that contain a variety of such articles and instructions concerning their use. Likewise, methods for preparing a customized laundry solution to obtain a specific fabric care benefit selected based on the user'"'"'s personal preferences and/or the fabric care needs of the fabrics being laundered are also provided. Further, the present invention also concerns methods for assisting a consumer in identifying the unitized articles to be used in preparing a laundry solution that will impart desired fabric care benefits as well as merchandising displays for dispensing the articles, assembling customized laundry kits and instructing the consumer on the selection and use of laundry articles.

Claims

1. An article for dispensing in a laundry wash and/or rinse cycle comprising an outer coating or film that is at least partially water-soluble that encapsulates a fabric care composition comprising:

a. a unitized dose of a silicone, wherein said silicone comprises from about 4% to about 99% by weight of said fabric care composition; and

b. less than about 3 grams of a detergent surfactant.

2. The article of claim 1, wherein said fabric care composition delivers less than about 47 ppm of said detergent surfactant in a volume of wash water comprising from about 64 L to about 75 L.

3. The article of claim 1, comprising from about 0.05 grams to about 60 grams of a fabric care composition.

4. The article of claim 1, wherein said fabric care composition further comprises from about 0.0025 grams to about 3 grams of said detergent surfactant by weight of said fabric care composition.

5. The article of claim 1, wherein said fabric care composition comprises less than about 5% of said detergent surfactant by weight of said fabric care composition.

6. The article of claim 1, wherein said fabric care composition further comprises a fabric softening active.

7. The article of claim 1, wherein said fabric care composition comprises from about 4% to about 60% of said silicone by weight of said fabric care composition.

8. The article of claim 1, wherein said silicone polymer is selected from polydimethylsilicones, aminosilicones, hydroxysilicones, polydimethyl siloxane, polydimethyl polysiloxane, and mixtures thereof.
