Decontamination formulation with additive for enhanced mold remediation
View Patent ↗Decontamination formulations with an additive for enhancing mold remediation. The formulations include a solubilizing agent (e.g., a cationic surfactant), a reactive compound (e.g., hydrogen peroxide), a carbonate or bicarbonate salt, a water-soluble bleaching activator (e.g., propylene glycol diacetate or glycerol diacetate), a mold remediation enhancer containing Fe or Mn, and water. The concentration of Fe 2+ or Mn 2+ ions in the aqueous mixture is in the range of about 0.0001% to about 0.001%. The enhanced formulations can be delivered, for example, as a foam, spray, liquid, fog, mist, or aerosol for neutralization of chemical compounds, and for killing certain biological compounds or agents and mold spores, on contaminated surfaces and materials.

water (balance).
2. An aqueous decontamination formulation comprising a mixture of:
about 2% benzalkonium chloride;
about 2% propylene glycol diacetate or glycerol diacetate;
about 2-5% hydrogen peroxide;
