Abstract

A process for making surfactant granules involving: (a) providing a surfactant component selected from the group consisting of a surface-active protein, a surface-active protein derivative, and mixtures thereof; (b) providing a disintegrator component; (c) combining the surfactant component and the disintegrator component to form a surfactant mixture; and (d) granulating and compacting the surfactant mixture to form the surfactant granules.

Claims (21)

1. A process for making surfactant granules comprising forming a surfactant mixture comprising:

(a) a surfactant component comprising a member selected from the group consisting of surface-active proteins, surface-active protein derivatives, and mixtures thereof; and

(b) a disintegrator component comprising a member selected from the group consisting of polysaccharides, polyvinyl pyrrolidone, polyurethane, polyacrylates, polyethylene glycols, alginic acids, alginates, layer silicates, and mixtures thereof; whereby,

surfactant granules with an improved dissolution rate are formed.

2. The process of claim 1 wherein the surfactant component comprises a member selected from the group consisting of protein hydrolyzates, protein fatty acid condensates, and mixtures thereof.

3. The process of claim 1 wherein the surfactant component further comprises an auxiliary surfactant component selected from the group consisting of anionic surfactants, nonionic surfactants, and mixtures thereof.

4. The process of claim 3 wherein the surfactant component and the auxiliary surfactant component are present in the granules in a ratio by weight of from about 1:10 to 10:1.

5. The process of claim 3 , wherein, the surfactant component comprises water-containing paste or dry solids.

6. The process of claim 1 , wherein, the surfactant mixture is granulated in a fluidized bed before compacting.

7. The process of claim 1 , wherein, the surfactant component and disintegrator component are present in the surfactant granules in a ratio by weight of from about 1:10 to 10:1.

8. The process of claim 7 , wherein, the surfactant component and disintegrator component are present in the surfactant granules in a ratio by weight of from about 5:1 to about 1:5.

9. The process of claim 8 , wherein, the surfactant component and disintegrator component are present in the surfactant granules in a ratio by weight of from about 2:1 to about 1:2.

10. A cleaning composition containing the surfactant granules of the process of claim 1 .

11. A cleaning composition comprising from 1% to 90% by weight of the granules of the process of claim 1 .

12. The cleaning composition of claim 11 comprising from 5% to 50% by weight of the granules of the process of claim 1 .

13. The cleaning composition comprising from 10% to 25% by weight of the granules of the process of claim 1 .

14. A cleaning composition comprising from 1% to 90% by weight of the granules of the process of claim 4 .

15. The cleaning composition comprising from 5% to 50% by weight of the granules of the process of claim 4 .

16. The cleaning composition comprising from 10% to 25% by weight of the granules of the process of claim 4 .

17. The cleaning composition comprising from about 5% to about 50% by weight of the surfactant granules of the process of claim 6 .

18. The cleaning composition comprising from about 5% to about 50% by weight of the surfactant granules of the process of claim 7 .
