Enzyme stabilized detergent compositions
View Patent ↗Biodegradable detergent compositions comprising enzymes and 1,3-propanediol are provided. The 1,3-propanediol in the composition is biologically derived and enhances the stability of the enzymes in the composition. The compositions also exhibit a low anthropogenic CO 2 emission profile.
1. A detergent composition comprising 1,3-propanediol and an enzyme, wherein the composition is biodegradable and wherein the 1,3-propanediol is biologically derived and enhances the stability of the enzyme.
2. The composition of claim 1 , wherein the weight percent of enzyme in the composition is between about 0.0001% and about 5.0%.
3. The composition of claim 1 , wherein the enzyme is selected from the group consisting of amylase, protease, Alcalase®, and Termamyl®.
4. The composition of claim 1 , further comprising borate or boric acid.
5. The composition of claim 4 , wherein the weight percent of borate or boric acid in the composition is less than about 5.0%.
6. The composition of claim 1 , wherein the composition is substantially free of borate or boric acid.
7. The composition of claim 1 , wherein the 1,3-propanediol has 50% biobased carbon.
8. The composition of claim 1 , wherein the 1,3-propanediol has 100% biobased carbon.
9. The composition of claim 1 , wherein said detergent composition is selected from the group consisting of dish-washing detergents, laundry detergents, clothing softeners, laundry bar soaps and car wash detergents.
10. The composition of claim 1 , wherein the composition has a lower anthropogenic CO 2 emission profile as compared to a biodegradable composition comprising 1,3-propanediol with a bio-based carbon content of 0%.
11. A method of enhancing enzyme stability in a detergent composition containing an enzyme, the method comprising the step of providing a detergent composition containing an enzyme, and combining 1,3-propanediol to the detergent composition, wherein the composition is biodegradable and wherein the 1,3-propanediol is biologically derived and enhances the stability of the enzyme.
12. The method of claim 11 , wherein the weight percent of enzyme in the composition is between about 0.0001% and about 5.0%.
13. The method of claim 11 , wherein the enzyme is selected from the group consisting of amylase, protease, Alcalase®, and Termamyl®.
14. The method of claim 11 , further comprising borate or boric acid.
15. The method of claim 14 , wherein the weight percent of borate or boric acid in the composition is less than about 5.0%.
16. The method of claim 11 , wherein the composition is substantially free of borate or boric acid.
17. The method of claim 11 , wherein the 1,3-propanediol has 50% biobased carbon.
18. The method of claim 11 , wherein the 1,3-propanediol has 100% biobased carbon.
19. The method of claim 11 , wherein said detergent composition is selected from the group consisting of dish-washing detergents, laundry detergents, clothing softeners, laundry bar soaps and car wash detergents.
20. The method of claim 11 , wherein the composition has a lower anthropogenic CO 2 emission profile as compared to a biodegradable composition comprising 1,3-propanediol with a bio-based carbon content of 0%.
