aqueous mixtures of the invention to pseudoplastic non-New› tonian solutions for use with a range of high performance nozzles including, but not limited to, ultrasonic nozzles. 

[0220] Surface active components of the organic/aqueous mixtures are also useful for forming microemulsion fogs that enhance aerosol decontamination by increasing (i) the rates oftoxant hydrolysis, (ii) the aerosol persistence of the decon› taminating solution when dispersed through high perfor› mance nozzles; and (iii) the area covered per unit volume of decontaminant. The surfactant components can also form microemulsion sprays that enhance surface decontamination when dispersed through high performance nozzles. In this case, the surface active components form a thin film that holds the decontamination solution on the surface to be decontami› nated. Thus, other embodiments of the present invention include methods of forming microemulsion fogs or sprays when dispersed through high performance nozzles. 

[ 0221] One embodiment of the present invention are decon› tamination solutions with minimum viscosity at the disper› sion nozzle, but optimum viscosity for diffusion and retention on the target surface Such formulations produce medium sized droplets with no change in droplet size with speed, pressure, flow fluctuations, and temperature. To compare droplet sizes produced by different nozzle designs, droplet diameters derived using the same assessment method must be used. FIG. 10 shows how droplet size is determined. Viscosity and surface tension are the two main factors that influence droplet size. Generally, as viscosity or surface tension is increased, the forces required to generate droplets increases. This increase in required force results in less energy available for atomization. Hence, viscous liquids or those with high surface tension tend to form more coarse droplets. Moreover, as flow rate increases, an increase in droplet size is also observed. In the case of air atomizers, increasing the shear velocity of the liquid will decrease droplet size. The shear velocity is a function of viscosity. 

[0222] According to certain aspects of the invention, meth› ods of decontaminating toxants can use a decontamination solution comprising an aqueous/organic solution providing certain capabilities. Specifically, the solution can rapidly dis› solve full threat loads of toxants in a homogeneous, isotropic solution; can rapidly dissolve reactive oxygen species or their dry sources in sufficient concentrations to rapidly and com› pletely hydrolyze or otherwise neutralize full threat; can rap› idly dissolve loads oftoxants in small volume ratios of decon› taminant solution to toxant; and can remain a low viscosity liquid with a low vapor pressure from about 125° F. to about -25° F. Further, the solution can also improve the reaction kinetics of decontamination; can minimize the volume ratio of decontamination solution/toxant for greater efficacy; can utilize surfactant/block co-polymer synergies to create non› Newtonian solutions; and can minimize damage to sensitive equipment (e.g., electronics and specialized materials). The solution should also have a sufficiently low vapor pressure and high flash point, to ensure easy and safe shipping, storage, and use. In addition, ease of cleanup and disposal of the solution and the toxant by-products is desirable, as are envi› ronmental safety and biodegradability. 

[0223] Another aspect of the invention relates to systems comprising the decontaminants of the instant invention. One system configuration for any of the polyol based formulations can comprise four parts: the base mix, at least one liquid activator (which may be two liquid activators), and a dry activator. This format is known as a quaternary system (FIG. 

13). Alternative system configurations can comprise three parts (a ternary kit) or two parts (a binary kit). The latter system would include a base solution which contains all of the components except either (i) the reactive oxygen species or its source, or (ii) the liquid activator or dry activator or source thereof. The binary system configuration of the present inven› tion (FIG. 14) has the peroxy acid source(s) dissolved in their stable unactivated states in the base mix, and the activator source, in either its stable liquid or dry source, would be contained in a separate container. 

[0224] The system components can be routinely supplied in two, three, or four containers, depending upon the system configuration. The components can be mixed on an as-needed basis in the required volumes. In addition, the base mix can be shipped fully diluted with water, or, in the case of the high flash point polyol based formulations, shipped without the water fraction. Certain embodiments of the invention com› prise mixed components as a solution ready for deployment. Other embodiments include hardware for dispersal of decon› tamination solutions as either an aerosol fog or as a spray for surface applications. Other embodiments of the invention use the solutions as fogs or sprays to hydrolyze chemical toxants. 

[0225] The following examples illustrate concepts related to the present invention. 

[0226] The melting point of a solution of 9% isopropyl alcohol PA, 9% H$_{2}$O$_{2}$ , and 82% H$_{2}$O by volume can be determined. CH 3 ----CH(CH 3 )-OH does not dissociate appreciably and forms an ideal solution. 2 moles of hydrogen peroxide are disproportionate 

so the solute is CH 3 ----CH(CH 3 )-OH. The concentration of CH 3 -CH(CH 3 )-OH is 8% v/v=80 ml/L; the density of CH 3 -CH(CH 3 )-OH=0.7855 g/ml; the solution contains 0.7855 g/mlx80 ml=62.84 g; the molecular weight ofCH 3 - CH(CH3)-OH=60.10 g/M. 62.84 g/60.10 g/M=l.046 Moles is added to 920 ml water with a density of 1 g/ml. Then ll T=kfm=l.86° C. kg mol-$^{1}$xl.137 molal=2.11 ° C. and the freezing Point=(0-2.11)° C.=-2.11 ° C. 

[0227] The amount of glycol (1,2-ethane-diol), C$_{2}$H$_{6}$O$_{2 }$ which must be added to 1.00 L of H$_{2}$O such that the solution does not freeze above -20° C. may be calculated as follows:

where kf (H$_{2}$0)=1.86° C. kg mol-1; llT=i kf m where i=l. Since 1.0 Lhasa mass of 1.0 kg, 10.8 mo! of ethylene glycol is needed, so 10.8 molx62 g/mol=670 grains of ethylene glycol. The density of ethylene glycol is 1.1088. Therefore, 670 g/1.1088 g/mL=604 ml, which is dissolved in 1 L=6.04 ml in 10 ml. At this concentration, the viscosity of such a solution renders it unusable for aerosol spraying. 

[0228] The amount of NaCl that must be added to 1.00 L of H$_{2}$O to decrease the freezing point to -20° C. can be calcu› lated:
