Abstract

Complexes of boron and alkyl ether terminated silane polyethers are described. Compositions incorporating such complexes are also described. In addition to the boron-silane polyether complex, such compositions include water and one or more enzymes. Compositions further containing actives and/or polyols are also described. Uses for such compositions include disinfection.

First claim

The invention claimed is:

1. A complex of an alkyl ether-terminated silane polyether and a boron compound, wherein the alkyl ether-terminated silane polyether has the formula:

wherein m and n are independently selected integers and range from 8 to 30, and R1 and R2 are linear or branched alkyl groups having 1 to 6 carbon atoms; and wherein the boron compound is selected from the group consisting of boric acid and borax.

2. The complex of claim 1 , wherein R1 and R2 are methyl groups.

3. The complex of claim 1 , wherein m and n are each at least 12 and no greater than 24.

4. The complex of claim 3 , wherein m and n are each at least 16 and no greater than 20.

5. The complex of claim 4 , wherein m and n are each 18.

6. The complex of claim 1 , wherein the boron compound is boric acid.

7. The complex of claim 1 , wherein the boron compound is borax.

8. A composition comprising water, at least one enzyme, and the complex according to claim 1 .

9. The composition of claim 8 , wherein the molar ratio of the boron compound to the silane polyether is from 90:10 to 30:70.

10. The composition of claim 9 , wherein the molar ratio of the boron compound to the silane polyether is from 70:30 to 40:60.

11. The composition of claim 8 comprising at least 0.5 wt. % and no greater than 2 wt. % of the silane polyether, wherein at least a portion of the silane polyether is complexed with the boron compound.

12. The composition of claim 8 comprising at least 2 wt. % and no greater than 5 wt. % of the boron compound.

13. The composition of claim 8 , further comprising a polyol.

14. The composition of claim 13 , wherein the polyol is selected from the group consisting of sugars, sugar alcohols, sugar acids, glycerol, and uronic acid, and combinations thereof.

15. The composition of claim 14 , wherein the polyol is selected from the group consisting of glycerol, glucose, and combinations thereof.

16. The composition of claim 13 comprising 2 to 4 wt. % of the polyol.

17. The composition of claim 8 , wherein the enzyme is selected from the group consisting of amylases, cellulases, lipases, proteases, and combinations thereof.

18. The composition of claim 17 comprising a plurality of enzymes selected from at least three of amylases, cellulases, lipases, and proteases.

19. The composition of claim 8 , further comprising an active selected from the group consisting of hydrogen peroxide, aldehydes, quaternary ammonium salts, acids, and combinations thereof.

20. The composition of claim 8 , wherein the pH of the composition increases by at least 1 upon dilution with 300 parts water per 1 part of the composition.
