Abstract

A composition that can decontaminate opioids on surfaces or objects, and in particular decontaminate fentanyls on surfaces using an opioid-active reagent and an opioid-effective solubilizing agent, which is a mixture of an alkyl dimethylamine oxide surfactant, an alkyl dimethylamine oxide surfactant, a C 8-18 alkyl polyethylene glycol sorbitan fatty ester surfactant, and a C 12-14 secondary alcohol ethoxylate surfactant. Preferably, the opioid-active reagent is chlorine dioxide. Additionally, methods for decontaminating opioids on surfaces using this composition.

First claim

What is claimed is:

1. A composition for decontaminating opioids, the composition comprising an opioid-active reagent and an opioid-effective solubilizing agent, wherein the opioid-effective solubilizing agent is a mixture of an alkyl dimethylamine oxide surfactant, an alkyl dimethylamine oxide surfactant, a C 8-18 alkyl polyethylene glycol sorbitan fatty ester surfactant, and a C 12-14 secondary alcohol ethoxylate surfactant.

2. A method of decontaminating opioids, the method comprising the step of applying the composition of claim 1 to a surface or an object contaminated with an opioid; and, using the composition of claim 1 to chemically convert the opioid into an opioid reaction product.

3. The method of claim 2 further comprising the step of providing mechanical energy to the composition of claim 1 in contact with the opioid to enhance mixing between the composition and the opioid.

4. The method of claim 3 , wherein the mechanical energy is either stirring, spraying, power washing, brushing, ultrasonic energy, or combinations thereof.

5. The method of claim 2 , wherein the composition of claim 1 further comprises an opioid-effective solubilizing agent.

6. The method of claim 5 , wherein the opioid-active reagent has a chemical reactivity such that the opioid-active reagent converts a fentanyl into an opioid reaction product.

7. The method of claim 6 , wherein the opioid-active reagent is selected from the group consisting of chlorine dioxide, a peroxide, an organic peroxide, a peracetic acid, trichloroisocyanuric acid and sodium dichloroisocyanurate.

8. The method of claim 7 , wherein the opioid-active reagent is chlorine dioxide.

9. The method of claim 7 , wherein the composition further comprises a chlorine dioxide precursor.

10. The method of claim 9 , wherein the chlorine dioxide precursor is sodium chlorite.

11. The method of claim 10 , wherein the composition further comprises an acid that promotes conversion of sodium chlorite to chlorine dioxide.

12. The method of claim 10 , wherein the composition further comprises an organic photoactivator to promote conversion of sodium chlorite to chlorine dioxide;
and the method further comprising the steps of exposing the composition to light and photogenerating chlorine dioxide.
