Air purification candle

A method for air purification, the method comprising:

• providing a candle comprising a wax composition, wherein the wax composition comprises:
• a blend of long-chain waxes, medium-chain waxes, and short-chain waxes, wherein the long-chain waxes comprise hydrogenated waxes having carbon chain lengths of C38-C44 and are present in an amount of 0-15% of a total composition of the wax composition, the medium-chain waxes comprise waxes having carbon chain lengths of C16-C20 and are present in an amount of 60-100% of the total composition of the wax composition, and the short-chain waxes comprise waxes having carbon chain lengths less than C16 and are present in an amount of 0-15% of the total composition of the wax composition;
• a plurality of metal nanoparticles embedded within the wax composition and are to be released into surrounding air during burning of the candle for neutralizing airborne pathogens, wherein the plurality of metal nanoparticles are uniformly dispersed within the wax composition through high-shear mixing, and wherein:
• the plurality of nanoparticles are less than 50 nm in size,
• are composed of alloy metals comprising silver, copper, zinc, or gold alloys, or a combination thereof, and are coated, and
• are present in a concentration range of 1 to 50 micrograms of nanoparticles per gram of wax composition;
• and
• a wick for burning the wax composition;
• burning the candle to release the plurality of metal nanoparticles and metal ions into the surrounding air,
• wherein burning the candle releases metal nanoparticles into the surrounding air creating charged nucleation points that attract airborne particulates to form complexes infused with the plurality of metal nanoparticles, and wherein burning the candle achieves at least 60% reduction in airborne microorganisms selected from the group consisting of Gram-positive bacteria, Gram-negative bacteria, enveloped viruses, non-enveloped viruses, yeast, and mold spores.
