Abstract

A coupling agent composition is provided and includes a plurality of non-toxic components in an amount equal to or greater than 97 weight percent (wt %). The coupling agent composition includes a carrier of water, at least one water soluble polyol selected from the group consisting of propanediol, pentylene glycol, and butylene glycol, a thickening agent having a naturally derived soluble polymer additive selected from a group consisting of xanthan gum, carrageenan, guar, locust bean, sodium hyaluronate, sodium alginate, acacia, tara gum, tamarind seed, succinoglycan, scleroglucan, and mannan, and a balance of incidental impurities.

Claims (26)

1. A coupling agent composition containing:

a plurality of non-toxic components in an amount equal to or greater than 97 weight percent (wt %) and having:

a carrier of water;

at least one water soluble polyol selected from the group consisting of propanediol, pentylene glycol, and butylene glycol;

a thickening agent having a naturally derived soluble polymer additive selected from a group consisting of xanthan gum, carrageenan, guar, locust bean, sodium hyaluronate, sodium alginate, acacia, tara gum, tamarind seed, succinoglycan, scleroglucan, and mannan; and

a balance of incidental impurities.

2. The composition according to claim 1 , wherein the naturally derived soluble polymer additive is in an amount of 0.50-3.00 wt %.

3. The composition according to claim 2 , wherein the at least one water soluble polyol is in an amount of from 9.00 to 11.00 wt %.

4. The composition according to claim 3 , further comprising a neutralizing agent selected from a group consisting of sodium hydroxide, triethanolamine, tromethamine, arginine, and lysine.

5. The composition according to claim 4 , further comprising a chelating agent selected from a group consisting of disodium EDTA and sodium phytate.

6. The composition according to claim 5 , wherein the neutralizing agent is in an amount of from 0.05 to 0.50 wt %.

7. The composition according to claim 6 , wherein the chelating agent is in an amount of from 0.025 to 0.10 wt %.

8. The composition according to claim 1 , wherein the water has a pH in the range of 6.0 to 8.0 wt %.

9. The composition according to claim 1 , wherein the at least one water soluble polyol is in an amount of from 9.00 to 11.00 wt %.

10. The composition according to claim 9 , wherein the wherein the at least one water soluble polyol is processed from fermentation or enzymatic synthesis.

11. The composition according to claim 10 , wherein the fermentation or enzymatic synthesis is a natural chemical process using bacteria or yeast to convert organic materials.

12. The composition according to claim 11 , wherein the thickening agent is less than or equal to 3 wt %.

13. The composition according to claim 12 , wherein the thickening agent is synthetic nontoxic swellable polymer.

14. The composition according to claim 13 , wherein the thickening agent is at least one cross-linked polymer selected from a group consisting of hydrophobic polyacrylate or hydrophilic polyacrylate.

15. The composition according to claim 14 , wherein the at least one cross-linked polymer is selected from a group consisting of hydrophobic polyacrylate or hydrophilic polyacrylate.

16. The composition according to claim 1 , wherein a viscosity of the composition is 25000-100000 centipoise.

17. The composition according to claim 1 , further comprising a biocide agent.

18. The composition according to claim 17 , wherein the biocide agent is selected from a group consisting of phenoxyethanol, benzyl alcohol, caprylyl glycol, ethylhexylglycerin, decylene glycol, and 1,2-hexanediol.

19. The composition according to claim 1 , wherein the carrier of water and the at least one water soluble polyol is present in an amount of from 15 to 19 wt %.

20. The composition according to claim 19 , wherein the at least one water soluble polyol is propanediol.

21. The composition according to claim 1 , wherein the plurality of non-toxic components is propylene glycol free.
