Ingredients and Their Functions in Fog Machine Juice

Fog machine juice primarily consists of a combination of water, glycol or glycerin, and sometimes additives to enhance performance or safety. Understanding the role each ingredient plays is crucial for creating an effective and safe fog fluid.

Water acts as the base solvent, providing the medium in which the fog-producing compounds dissolve. It evaporates rapidly when heated, helping to disperse the fog particles into the air.

Glycols, such as propylene glycol or ethylene glycol, are the key fog-forming agents. These compounds have a low vapor pressure and high boiling points, which allows them to vaporize and condense into visible fog when expelled from the machine. Propylene glycol is preferred for its lower toxicity compared to ethylene glycol, making it safer for indoor use.

Glycerin, a viscous liquid, is often used as an alternative or supplement to glycols. It produces a thicker, longer-lasting fog but may require careful dilution to avoid residue buildup in the machine.

Additives may include preservatives to extend shelf life, anti-foaming agents to prevent excessive bubbling during heating, and fragrances to mask any chemical odors.
