Abstract

Disclosed herein are foamed gel air-treating compositions that have at least 50% water, between 1 and 15 percent soap surfactant, a volatile fragrance, at least 0.1 percent carbon, and a foam stabilizer. These compositions can fragrance a room as well as adsorb malodors in the room. Methods for forming these foamed gels are also disclosed.

Claims

1. A foamed gel air-treating composition, comprising:

at least 50% by weight water;

between 1 and 15 percent by weight soap surfactant;

a volatile fragrance; and

at least 0.1 percent by weight carbon as carbon.

2. The foam gel air-treating composition of claim 1, further comprising a foam stabilizer.

3. The foam gel air-treating composition of claim 2, wherein the foam stabilizer is a nitrogen containing surfactant.

4. The foam gel air-treating composition of claim 3, wherein the foam stabilizer is selected from the group consisting of amine oxides, amids and betaines.

5. The foam gel air-treating composition of claim 1, wherein the soap surfactant is a stearate salt.

6. The foam gel air-treating composition of claim 1, wherein the carbon is selected from the group consisting of charcoal, activated charcoal and coke.

7. The foam gel air-treating composition of claim 1, wherein the composition is in the form of a bulk, and a majority of the carbon is on an outside surface of the bulk.

8. The foam gel air-treating composition of claim 1, further comprising polyvinyl alcohol.

9. A method for forming a bulk of the composition of claim 2, comprising:

stirring the water, soap surfactant, fragrance, and foam stabilizer at a temperature sufficient to provide a soap solution;

then stirring the water, soap surfactant, fragrance, and foam stabilizer at a temperature between 28 C. and 43 C. to generate a foam gel matrix; and

thereafter allowing the composition to form a bulk and adding carbon to at least an outer exposed surface of the bulk.

10. A method for fragrancing and at least partially deodorizing air in a room having a malodor, comprising:

exposing the air in the room to a bulk of the claim 1 composition and allowing fragrance to disperse from the bulk to the air and allow a portion of the malodor to bind to the bulk.
