  • the present invention relates to glove with surface area coated with long acting broad spectrum antimicrobial formulation.
  • the disclosed invention is capable of exerting rapid killing of contacted hazardous microbes and sustaining the antimicrobial property in an exposed environment for an extended duration.
  • Disposable gloves are manufactured to be readily discarded upon utilization. Disposability of these gloves not only aims to reduces the likelihood of the user being exposed to such microbes contaminated-gloves after repeated use.
  • Some of the gloves such as protective gloves or facial mask, are particularly used in a condition which avoid transfer of microbial agent from an object to the user or vice versa.
  • protective gloves are widely used in hospitals, pharmaceutical plants, food plants, kitchens or even public place to isolate microorganisms from being transferred to or out of the user's hand so as to reduce the risk of microbial cross contamination. Nevertheless, once microbes attached to the surface of the glove are not halted or killed, the attached microbes may proliferate on the glove surface rendering the contaminated gloves a potential cross contaminating source.
  • facial masks are used to minimize inhalation or transmitting of airborne pathogens at household, schools healthcare, industrial etc.
  • the typical pore size is usually too big to effectively block the pathogens.
  • effort has been put in to have an effective antimicrobial coating made onto the surfaces, which are actively exposed to potential microbe contamination, of these glove to rapidly kill microorganisms upon contact the coated surface.
  • United Kingdom patent application no. 1337617 details surgical gloves with antimicrobial substances coated at the finger portion of the gloves to minimize cross- contamination.
  • Another United Kingdom patent application no. 2218617 describes another glove incorporated with non-ionic sparingly water soluble antimicrobial agent to form additional barrier to prevent infection caused by breach of microbes.

  • the antimicrobial property available on these products remains intact during this exposure time despite being constantly challenged by air impurities, moisture, humidity, organic matter or microorganisms. Failure in sustaining the antimicrobial property mainly attribute to the antimicrobial agents used in these prior arts do not exert sustained activity and the formulation is not stable over the surface for extended period of time. For example, earlier attempts of using antimicrobial agent such as chlorhexidine in mask failed to provide sustained activity or rapid kill-rate necessary to protect a user to minimize the risk of cross contamination when exhaling.
  • the present invention aims to disclose gloves equipped with antimicrobial property to avoid proliferation of harmful microbes on the gloves which is likely to serve as a source of cross- contamination or infectious agent.

This contribute to an overall hygiene and lesser product spoilage as well as greater product acceptance by achieving rapid and broad-spectrum kill of spoilage microorganisms.
  • Object of the present invention also involves providing glove having a stable antimicrobial coating even subjected to environmental challenge.
  • Earlier antimicrobial compounds has less tolerance to organic matter challenge on surfaces well. In fact, mere 10% organic matter challenge reduces chlorine efficacy by 50%.

  • Further object of the present invention is to provide a gloves which is substantially environmental friendly compared to some prior similar inventions.

It was found by the inventors of the present invention that the antimicrobial formulation is chemically stable over a long period of time without much decline in killing efficiency. In more specific, through appropriate proportion of different antimicrobial agents in the formulation, the disclosed invention is able to achieve extended antimicrobial property albeit facing various challenges in an open environment, particularly in an open or broken box condition which the packaged gloves are subjected to environmental challenge.

  • urea that it enhances the kill efficiency and stabilizes the coating on the gloves. It is known that pores and crevices are naturally occurred on the surface of the gloves such as gloves and conventional antimicrobial compounds, restrained by surface tension, are incapable of penetrating into these pores or crevices to achieve effective kill. This provides opportunity for microbes to quickly multiply in numbers on the surfaces when condition is ideal for growing (typical in hot and humid storage and using conditions).
  • the incorporation of GRAS urea on the surface coating lower the surface tension of water or moisture presented on the treated surface. Thus, the disrupted water or moisture with other dissolved antimicrobial agent can penetrate into pores and crevices on the irregular surfaces of the gloves.
  • the GRAS urea further potentiates the quaternary ammonium chloride (QAC) molecules in the antimicrobial activity synergistically.
  • QAC molecules alone have limited efficacy to destroy non-enveloped viruses, endospores and Gram negative bacteria such as Pseudomonas spp.. Yet, in the presence of GRAS urea, the QAC can effectively act on these microbes disrupted by the GRAS urea.
  • QAC shows low tolerance to hardwater (only up to 200ppm) and organic matter as well while a far more stable formulation of QAC suitable for wider pH, temperature and organic matter tolerance is achieved in the present invention with the addition of GRAS urea.

  • the antimicrobial formulation of the present invention incorporated with GRAS urea remains effective between pH3-l l ; typically in coagulant mixture of pH 10 used in online production of glove.

  • the chemical and heat stability of the disclosed formulation also allow the present invention to be manufactured through an online process.
  • the coagulant mix contains a multitude of chemicals and soluble solids that causes wide soluble solids variability and hardness. The wide range renders earlier antimicrobial formulations ineffective. Most antimicrobial compounds tend to lose their antimicrobial property when soluble solids and hardness exceeds 300ppm in the coagulant, while the typical coagulant mix in nitrile and latex glove manufacturing ranges between 3,000 - 220,000ppm. Nevertheless, the antimicrobial formulation used in the present invention remains effective even after the gloves are produced from such drastic processes..
  • the active agents of the coated antimicrobial formulation In order to achieve rapid and effective kill, the active agents of the coated antimicrobial formulation, particularly the 5 th generation quaternary ammonium chloride derived compound, needs to attain a preferable concentration of 300 to 6000 ppm on the treated surface area. Effective eradication may not be able to complete for any concentration lower than 400ppm, while concentration above 6000 ppm is made redundant.
