• Reduced VOC Content: Eco-friendly antimicrobial coatings are formulated with low or zero VOC content, minimizing the release of harmful chemicals into the atmosphere. This reduction in VOCs helps improve indoor air quality and reduces the overall environmental footprint of the coating.

Water-Based Coatings Offer Long-Lasting Protection

Novel coatings such as LapisShield by Microban provide long-lasting protection for water-based coatings and can be applied to a broad spectrum of substrates. The active ingredient disrupts bacteria's internal enzymes to block metabolic pathways and create an inhospitable environment that interrupts reproduction[1].

• Versatile Application: Water-based antimicrobial coatings can be applied to a wide range of surfaces, including plastics, metals, and textiles. This versatility allows for the protection of various manufacturing components, equipment, and facilities.

• Enzyme Disruption: The active ingredients in water-based coatings like LapisShield target specific enzymes within bacterial cells. By disrupting these enzymes, the coating interferes with the bacteria's metabolism and ability to reproduce, effectively controlling their growth.

• Durable Protection: Water-based antimicrobial coatings form a durable protective layer on surfaces. This durability ensures long-lasting antimicrobial activity, even under challenging manufacturing conditions such as high humidity or frequent cleaning.

Natural-Based Biocides Demonstrate Effectiveness

Natural-based biocides such as I3C and EUG are promising to be used in disinfectant formulations. I3C at 10 × MIC and 5500 mg/L was able to cause total CFU reduction of silicone and stainless steel deposited bacteria[2].

• Plant-Derived Compounds: I3C (indole-3-carbinol) and EUG (eugenol) are plant-derived compounds that exhibit strong antimicrobial properties. These natural biocides offer an eco-friendly alternative to synthetic antimicrobial agents.

• Effective Against Biofilms: Biofilms are communities of microorganisms that adhere to surfaces and are notoriously difficult to eradicate. Natural-based biocides like I3C have demonstrated the ability to effectively reduce biofilm formation on common manufacturing materials such as silicone and stainless steel.

• Synergistic Effects: Combining natural-based biocides with other antimicrobial agents can lead to synergistic effects, enhancing overall antimicrobial efficacy. This synergy allows for lower concentrations of individual components, further reducing the environmental impact.

Plant-Based Edible Coatings Enhance Food Preservation

Plant-based edible coatings can effectively maintain the quality, freshness, and nutritional value of food products. They can be incorporated with antimicrobial agents and antioxidants, further extending the shelf life of food[4].

• Natural Ingredients: Plant-based edible coatings are derived from renewable sources such as polysaccharides, proteins, and lipids. These natural ingredients are biodegradable and non-toxic, making them an eco-friendly choice for food packaging applications.

• Antimicrobial Properties: Edible coatings can be infused with natural antimicrobial agents, such as essential oils, organic acids, and bacteriocins. These agents inhibit the growth of spoilage microorganisms and foodborne pathogens, thereby extending the shelf life of food products.

• Reduced Packaging Waste: By applying edible coatings directly onto food surfaces, the need for additional plastic packaging can be reduced. This reduction in packaging materials contributes to a more sustainable and environmentally friendly food supply chain.

Green Seal Certification Ensures Low-VOC and Safer Formulas
