Abstract
Official abstract text for this publication.
A composition having water and first and second surfactants having the formulas below. The values m and y are non-negative integers, and n and x are positive integers. R is a zwitterionic group. R′ is a siloxane group. A foam of the composition may be used to extinguish a fire.
First claim
Opening claim text (preview).
What is claimed is: 1. A composition comprising: a first surfactant having the formula: a second surfactant having the formula: and water; wherein m, x, and y are independently selected non-negative integers; wherein n is a positive integer; wherein R is a zwitterionic group; and wherein R′ is a siloxane group. 2. The composition of claim 1 , wherein the first surfactant has the formula: 3. The composition of claim 1 , wherein R is a sulfobetaine group or a chlorobetaine group. 4. The composition of claim 1 , wherein m is from 0 to 20. 5. The composition of claim 1 , wherein n is from 1 to 20. 6. The composition of claim 1 , wherein x is from 0 to 4. 7. The composition of claim 1 , wherein y is from 0 to 5. 8. The composition of claim 1 , wherein the composition comprises more than one of the first surfactant or the second surfactant having different values of m, n, x, or y. 9. The composition of claim 1 , wherein first surfactant and the second surfactant have a wt. % ratio of 0.03 to 5. 10. The composition of claim 1 , wherein the composition further comprises: a solvent having the formula: wherein p and z are positive integers. 11. The composition of claim 10 , wherein p is from 1 to 8. 12. The composition of claim 10 , wherein z is from 1 to 6. 13. A method comprising: mixing the composition of claim 1 with air to form a foam. 14. The method of claim 13 , further comprising: applying the foam to a fire. 15. The method of claim 13 , further comprising: applying the foam to a fire in an amount sufficient to extinguish the fire. 16. A method comprising: mixing a first surfactant, a second surfactant, and water to form a composition; wherein the first surfactant has the formula: wherein the second surfactant has the formula: and water; wherein m, x, and y are independently selected non-negative integers; wherein n is a positive integer; wherein R is a zwitterionic group; and wherein R′ is a siloxane group. 17. The method of claim 16 , wherein the first surfactant has the formula: 18. The method of claim 16 , wherein the composition further comprises: a solvent having the formula: wherein p and z are positive integers.
