Abstract

A soap bar is provided, comprising: a soap; water; a cellulose derivative selected from the group consisting of a hydroxyalkyl alkyl cellulose; and an additive selected from the group consisting of a psyllium, a sodium silicate and mixtures thereof; wherein the soap bar is a solid.

First claim

We claim:

1. A soap bar, comprising:
35 to <75 wt %, based on weight of the soap bar, of a soap;
>23 to 40 wt %, based on weight of the soap bar, of water;
0.01 to 5 wt %, based on weight of the soap bar, of a cellulose derivative selected from the group consisting of a hydroxyalkyl alkyl cellulose; and
an additive is a mixture of
0.1 to 5 wt %, based on weight of the soap bar, of a psyllium; and
2 to 18 wt %, based on weight of the soap bar, of a sodium silicate;

wherein the soap bar is a solid.

2. The soap bar of claim 1 , wherein the cellulose derivative is selected from the group consisting of a hydroxyethyl methyl cellulose, a hydroxypropyl methyl celluose, hydroxyethyl cellulose and a mixture thereof.

3. The soap bar of claim 2 , further comprising 0.01 to 3 wt %, based on weight of the soap bar, of a processing aid.

4. The soap bar of claim 3 , further comprising 0.01 to 3 wt %, based on weight of the soap bar, of an optional component selected from the group consisting of at least one of a fragrance and a dye.

5. The soap bar of claim 4 , further comprising a filler; and wherein the soap bar is a laundry soap bar.

6. The soap bar of claim 4 , further comprising 0.1 to 5 wt %, based on weight of the soap bar, of a humectant; and wherein the soap bar is a personal cleansing soap bar.

7. The soap bar of claim 6 , further comprising 0.01 to 0.5 wt %, based on weight of the soap bar, of a chelating agent.

8. A method of making a soap bar, comprising:
providing a soap;
providing a psyllium;
providing a cellulose derivative selected from the group consisting of a hydroxyalkyl alkyl cellulose;
providing a sodium silicate;
providing water;
mixing the soap, the psyllium, the hydroxyalkyl alkyl cellulose, the sodium silicate and the water to form a combination;
milling the combination;
extruding the milled combination; and
stamping the extruded material to provide the soap bar.

9. The method of claim 8 , further comprising:
providing a fragrance; and
providing a processing aid;
wherein the fragrance and the processing aid are mixed along with the soap, the psyllium, the hydroxyalkyl alkyl cellulose, the sodium silicate and the water to form the combination.
