Abstract
Disinfectant compositions having long-term stability and efficacy are disclosed. More specifically, the compositions of the present disclosure are stable when subjected to both light and heat and efficacious against virus families including the SARS-CoV2 virus. The compositions comprise a nanoparticle anti-microbial agent, and one or more additional components selected from reducing agents, surface binding agents, wetting agents, matrix components, polymers, and reverse micellar surfactants. Methods for treating or impregnating textiles, including gloves, with the disinfectant composition comprising a nanoparticle anti-microbial agent are also disclosed.

A method of making an anti-microbial nitrile or rubber latex glove, the method comprising the steps of:
- a. dipping a glove former into a nitrile or rubber latex dispersion, which dispersion comprises a disinfectant composition comprising a nanoparticle anti-microbial agent to form a coated nitrile or coated rubber latex glove;
- and
- b. placing the coated nitrile or coated rubber latex glove into a packaging, wherein the packaging comprises a clear coat varnish impregnated with a disinfectant composition comprising a nanoparticle anti-microbial agent.
A method of making an anti-microbial nitrile or rubber latex glove, the method comprising the steps of:
- a. dipping a glove former into a coagulant solution containing divalent calcium cations and calcium nitrate particles, the coagulant solution further comprising a disinfectant composition comprising a nanoparticle anti-microbial agent, to form a coagulant-coated glove former;
- b. dipping the coagulant-coated glove former into a nitrile or rubber latex dispersion, which dispersion comprises a disinfectant composition comprising a nanoparticle anti-microbial agent to form a coated nitrile or coated rubber latex glove;
- and
- c. placing the coated nitrile or coated rubber latex glove into a packaging, wherein the packaging comprises a clear coat varnish impregnated with a disinfectant composition comprising a nanoparticle anti-microbial agent.
A method of making a stable disinfectant composition, the method comprising the steps of:
- a. combining at least one reverse micellar surfactant with water to form a transparent mixture;
- b. adding an effective amount of a nanoparticle antimicrobial agent to the transparent mixture to form a second mixture;
- c. adding an effective amount of at least one polymer and at least one matrix component to the second mixture to form a resultant formulation;
- and
- d. filtering the resultant formulation to form the stable disinfectant composition.
A method of making a stable disinfectant composition, the method comprising the steps of:
- a. combining at least one polymer with water to form an initial mixture;
- b. adding an effective amount of at least one reducing agent to the initial mixture to form a translucent mixture;
- c. adding an effective amount of a nanoparticle antimicrobial agent to the translucent mixture to form a second mixture;
- d. adding an effective amount of at least one polymer to the second mixture to form a resultant formulation;
- and
- e. filtering the resultant formulation to form the stable disinfectant composition.
