3. The liquid concentrate according to claim 1 wherein the pseudo-plastic, high yield, suspending agent comprises an acrylic acid copolymer cross linked with a polyalkenyl polyether.

4. The liquid concentrate according to claim 1 wherein the alcohol amine neutralizer comprises 2-amino-2-methly-1-propanol.

5. The liquid concentrate according to claim 1 wherein the non-ionic surfactant comprises an alkoxylated alcohol non-ionic surfactant.

6. The liquid concentrate according to claim 1 further comprising a smectite clay.

7. The liquid concentrate according to claim 1 wherein the liquid concentrate comprises less than 5 wt % water.

8. The liquid concentrate according to claim 6 wherein the smectite clay is present at a concentration of 0.1-5 wt %.

9. The liquid concentrate according to claim 1 comprising:

10-15 wt % starch;

33-38 wt % pseudo-plastic, high yield, suspending agent comprising acrylic acid copolymer cross linked with a polyalkenyl polyether;

35-45 wt % C 14-16 paraffin or C 14-16 olefin;

0.5-2 wt % non-ionic surfactant comprising alkoxylated alcohol non-ionic surfactant;

5-10 wt % alcohol amine neutralizer comprising 2-amino-2-methly-1-propanol; and

0.1-2.5 wt % smectite clay.

10. A method of forming a fire suppression non-aqueous liquid concentrate comprising:

combining a C 10-18 paraffin or a C 10-18 olefin with a non-ionic surfactant and an alcohol amine neutralizer to form a first liquid composition;

combining a pseudo-plastic, high yield, suspending agent to the first liquid composition to form a second liquid composition;

combining a smectite clay to the second liquid composition to form a third liquid composition; and

combining starch to the third liquid composition to form a fire suppression non-aqueous liquid concentrate; wherein the fire suppression non-aqueous liquid concentrate comprises:

0.1-20 wt % starch;

30-40 wt % pseudo-plastic, high yield, suspending agent;

30-50 wt % C 10-18 paraffin or C 10-18 olefin;

0.5-5 wt % non-ionic surfactant;

5-10 wt % alcohol amine neutralizer; and

0.1-5 wt % smectite clay.

11. The method according to claim 10 wherein the liquid concentrate comprises less than 5 wt % water.

12. The method according to claim 10 wherein first liquid composition is mixed until a homogenous first liquid composition is formed and the second liquid composition is mixed until a homogenous second liquid composition is formed and the third liquid composition is mixed until a homogenous third liquid composition is formed and the fire suppression non-aqueous liquid concentrate is mixed until a homogenous fire suppression non-aqueous liquid concentrate is formed.

13. The method according to claim 10 wherein the fire suppression non-aqueous liquid concentrate comprises:

10-15 wt % starch;

33-38 wt % pseudo-plastic, high yield, suspending agent comprising acrylic acid copolymer cross linked with a polyalkenyl polyether;

35-45 wt % C 14-16 paraffin or C 14-16 olefin;

0.5-2 wt % non-ionic surfactant comprising alkoxylated alcohol non-ionic surfactant;

5-10 wt % alcohol amine neutralizer comprising 2-amino-2-methly-1-propanol; and

0.1-2.5 wt % smectite clay.

14. A method comprising:

diluting the non-aqueous liquid concentrate of claim 1 with water to form a fire suppression dispersion comprising from 0.05 to 10 wt % non-aqueous liquid concentrate, wherein the fire suppression dispersion clings to a surface and forms an intumescent char coating upon fire contact.

15. The method according to claim 14 further comprising directing the fire suppression dispersion onto a surface to suppress fire.

16. The method according to claim 14 wherein the diluting occurs on a fire firefighting vehicle.

17. The method according to claim 14 wherein the diluting occurs within fire firefighting equipment.
