Compositions and methods for decontamination

DWPI Title: Decontaminating composition for decontaminating substrate, comprises a mixture of peroxide solution and surfactant composition, where the surfactant composition comprises e.g. xanthan gum, levulinic acid and ethyl lactate, and peroxide solution comprises hydrogen peroxide
Abstract: The disclosure relates to compositions, methods for making the compositions, and methods for decontaminating substrates wherein the decontaminating compositions comprise a mixture of a peroxide solution and a surfactant composition, wherein (i) the surfactant composition comprises: (a) from about 20% to about 40% xanthan gum, (b) from about 10% to about 25% levulinic acid, (c) from about 32% to about 63% ethyl lactate, and (d) from about 3% to about 7% polyoxyethylene (20) sorbitan monooleate, wherein all weights are relative to the total weight of the surfactant composition, (ii) the peroxide solution comprises from about 1% to about 12% hydrogen peroxide, and the mixture comprises from about 0.001 g to about 10 g of the surfactant composition per liter of the peroxide solution.
Use: Decontaminating composition for decontaminating substrate (claimed).
Advantage: The decontaminating composition leaves little to no harmful residue, and are less toxic and/or corrosive.
Novelty: A decontaminating composition comprises a mixture of a peroxide solution and a surfactant composition, where the surfactant composition comprises 20-40 wt.% xanthan gum, 10-25 wt.% levulinic acid, 32-63 wt.% ethyl lactate, and 3-7 wt.% polyoxyethylene (20) sorbitan monooleate, and the peroxide solution comprises 1-12 wt.% hydrogen peroxide. The mixture comprises 0.001-10 g surfactant composition per/L of the peroxide solution.
