Propylene glycol is a commonly used ingredient in fog liquids. It is responsible for creating the fog effect in fog machines. Fog liquids that use propylene glycol as the main component, like Antari fog liquids, are known for their safety. They are odorless, non-irritating, non-toxic, and non-flammable. This makes them an excellent choice for use in the entertainment industry, including theaters, photo shoots, and themed parties.
2. Water-based Fog Liquid
Water-based fog liquids are another common type of fog liquid. These fluids use distilled water as the primary ingredient, along with pharmaceutical-grade chemicals. They are known for producing atmospheric effects without leaving an oily residue. Water-based fluids are generally safe to use, as they do not pose any health risks or cause breathing difficulties. They are suitable for low-lying fog and can be used in combination with haze machines for creating visually stunning effects.
3. Oil-based Fog Liquid
Oil-based fog liquids, on the other hand, contain mineral oil as the primary ingredient. While they do create long-lasting fog with excellent hang time, there are some safety concerns associated with their use. Prolonged exposure to oil-based fog can cause eye and skin irritation. Additionally, they may pose a risk to smoke alarms and should be used with caution in enclosed spaces. It is important to carefully consider the type of fog machine and the specific requirements of the event or venue when choosing the type of fog liquid.
When choosing fog liquids, propylene glycol-based fluids and water-based fluids are excellent choices due to their safe ingredients and effectiveness in creating various types of fog effects.
Differences Between Propylene Glycol And Ethylene Glycol
Propylene glycol and ethylene glycol are two common ingredients used in fog machine fluids. While both substances are used to create theatrical effects and provide a realistic atmosphere, there are crucial differences in their safety and environmental impact. Propylene glycol is regarded as safe for humans and the environment compared to ethylene glycol.
When used in fog machines, these liquids need to be heated up, which can increase exposure to harmful substances. Antari, a leading manufacturer of fog machines, strictly controls the temperature of their fog machines to ensure that the fluid only heats up to 200 degrees, producing optimal fog with propylene glycol-based liquids.
Tests conducted by the Mount Sinai School of Medicine on behalf of the Actor’s Equity Association and the League of American Theaters and Producers have confirmed the safety of Antari’s fog liquid. Therefore, choosing fog fluids with propylene glycol as the primary ingredient is a safe and responsible choice for creating atmospheric and visual effects in the entertainment industry.
Is Propylene Glycol Or Glycerin Better For Fog Machines
When it comes to choosing between propylene glycol and glycerin for fog machines, it depends on the specific application. Propylene glycol is generally the least persistent, while glycerin can create more long-lasting effects. For applications where dense concentrations of fog are required, such as leak testing or fire training, glycerin is often recommended to ensure a more persistent fog.
However, for other uses in the entertainment industry or themed parties, propylene glycol may be a better choice due to its ability to create atmospheric and visual effects without leaving oily residue or posing health risks. Ultimately, the decision between propylene glycol and glycerin should be based on the desired effect, hang time, and safety concerns.
Can You Make Your Own Fog Juice
Yes, you can make your own fog juice using a basic composition of glycerin and water in a ratio of 1 part glycerin to 3 parts water. This simple formula allows you to adjust the thickness and density of the fog by adding more glycerin for a thicker fog or more water for a thinner fog.
Making your own fog juice can be a cost-effective and convenient option for creating atmospheric effects for entertainment industry applications, such as parties, photo shoots, or theatrical productions.
