What You'll Learn
DPG is dangerous to burn
DPG, or dipropylene glycol, is a liquid solvent used in preparing fragrances for incense. It is a cutting agent that dilutes fragrances and essential oils, allowing the fragrance to bind to the incense stick or cone so it burns slowly. However, despite its common use, DPG is not safe to burn.
DPG should not be burned as it can make people sick. The Material Safety Data Sheet (MSDS) on DPG lists hazardous decomposition products that are formed when burning, including oxides of carbon, and irritating aldehydes and ketones. The MSDS also lists conditions to avoid, such as extreme temperatures and pure oxygen. Acetaldehyde, one of the decomposition products, is toxic when applied externally for prolonged periods, is an irritant, and a probable carcinogen. It is a known upper respiratory tract irritant and can be found as a pollutant in indoor and outdoor environments.
The potential health risks of burning DPG-infused incense are serious. The smoke produced can contain harmful chemicals, and the indoor air quality can be negatively affected, leading to respiratory issues and other health problems. Even the process of making incense with DPG can be hazardous, as the dipping oils can contaminate the surrounding environment, including air ducts and HVAC systems.
While some may argue that DPG is safe, the potential risks outlined by the MSDS and the experiences of individuals who have used DPG in incense-making suggest otherwise. It is important for incense makers and users to be aware of the potential dangers and take the necessary precautions to ensure their health and safety. This may include opting for alternative fragrance carriers, such as jojoba oil, or choosing natural incense products that do not contain DPG.

DPG is a liquid solvent
DPG, or dipropylene glycol, is a liquid solvent used in the preparation of fragrances for incense. It is a cutting agent that dilutes fragrances and essential oils, allowing them to bind to incense sticks or cones and burn slowly. DPG is often used to create incense with fragrance oils, where the fragrance oil and DPG are mixed and the incense sticks are soaked in the mixture for 24 hours. This process is repeated batch after batch, topping off the fragrance oil and DPG as the levels lower.
DPG is a water-soluble, colorless liquid known for its low odor and volatility. It is an excellent solvent for organic materials and exhibits great solubility in water, soap bases, and oils. This makes it ideal for diluting and conveying fragrances and essential oils in various applications, such as incense making, diffusers, burning oils, and body oils.
One of the advantages of using DPG in incense-making is its ability to slow down the evaporation rate of scents, resulting in a long-lasting fragrance experience. It is also non-toxic and safe for skin contact, making it a standard choice in the industry.
However, it is important to note that DPG itself should not be burned as it is not safe and can make people sick. Burning DPG can produce hazardous decomposition products such as oxides of carbon, irritating aldehydes, and ketones. Therefore, it is crucial to follow the proper instructions and safety guidelines when using DPG for incense-making.

DPG is used as a cutting agent
DPG, or dipropylene glycol, is a liquid solvent used in preparing fragrances for incense. It is a cutting agent that helps to dilute fragrances and essential oils. This allows the fragrance to bind to the incense stick or cone so it burns slowly. DPG is also used to slow down the evaporation rate of scents, ensuring a long-lasting fragrance experience.
To use DPG as a cutting agent when making incense, it is recommended to mix one part fragrance oil to two parts DPG liquid. The incense sticks are then soaked in this scent mixture for 24 hours in a glass or HDPE plastic container. After soaking, the sticks are set on waxed paper (not paper towels) and allowed to dry completely for at least 48 hours before burning.
It is important to note that while DPG is widely used in the incense industry, it is not safe to burn. The Material Safety Data Sheet (MSDS) on DPG states that hazardous decomposition products, such as oxides of carbon, irritating aldehydes, and ketones, may be formed when burned. These decomposition products can be toxic and irritating to the respiratory tract. Therefore, it is recommended to use DPG as a cutting agent to dilute fragrances and essential oils but not to burn the DPG itself.
When working with DPG, it is crucial to take the necessary safety precautions. This includes avoiding extreme temperatures and pure oxygen conditions, as specified in the MSDS. Additionally, proper ventilation and protective gear, such as gloves and eye protection, are recommended when handling DPG to prevent any potential irritation or exposure to hazardous decomposition products.
By following these instructions and safety guidelines, incense makers can effectively use DPG as a cutting agent to create high-quality, fragrant incense sticks or cones with a slow burn and long-lasting fragrance.

DPG slows down the evaporation rate of scents
DPG, or dipropylene glycol, is a common ingredient used in incense-making. It is a water-soluble, colourless liquid known for its low odour and volatility. One of its key advantages is its ability to slow down the evaporation rate of scents, resulting in long-lasting fragrances. This makes it a preferred choice for incense makers who want to create incense with enduring aroma.
DPG acts as a cutting agent or solvent in incense-making. It helps to dilute fragrances and essential oils, allowing them to bind to the incense sticks or cones effectively. The standard ratio recommended for incense mixtures is one part DPG to one part fragrance oil. This mixture is then used to soak the incense sticks, which are later dried completely before burning.
The slow evaporation rate of DPG ensures that the fragrance is released gradually when the incense is burned. This not only enhances the longevity of the scent but also contributes to a more consistent and controlled release of the fragrance. As a result, incense made with DPG tends to have a smoother and more prolonged aroma compared to those without it.
While DPG is widely used in the incense industry, it is important to note that it should not be burned directly. Burning DPG can produce hazardous by-products, including oxides of carbon and irritating aldehydes and ketones. Therefore, it is crucial to use DPG as a component within incense sticks or cones rather than as a standalone burning agent.
Additionally, when working with DPG, it is essential to prioritise safety. DPG should be handled carefully, avoiding extreme temperatures and pure oxygen conditions. Proper ventilation and protective gear are recommended when working with this substance to prevent any potential health risks associated with prolonged exposure.
