Dipropylene glycol (DPG) is a versatile solvent that is commonly used as a fixative and booster in perfumes and colognes. It is an organic chemical compound that is almost odourless and colourless, with a high boiling point and low toxicity. When added to carrier oils, DPG dilutes the strength of fragrance oils, helping to slowly disperse the smell and increase the longevity of the perfume. It can be used to create fragrance oils at home by mixing it with essential oils, but it is important to note that not all essential oils are safe for skin contact. The recommended usage level for DPG in cosmetic applications is between 1% and 20%.

What You'll Learn
DPG is a safe, odourless, and colorless organic compound
Dipropylene glycol (DPG) is a type of organic chemical compound that is commonly used as a solvent in fragrances. It is a derivative of propylene glycol, with a longer carbon chain and three hydroxyl groups. DPG is colourless, odourless, and has a high boiling point.
DPG is a safe and effective ingredient for perfumes and fragrances. When added to carrier oils, it dilutes the strength of fragrance oils, slowly dispersing the smell. This makes it a great fixative and booster for perfumes, as it does not add any unnecessary odour to the fragrance. It is also safe for use on the skin and has low toxicity levels.
DPG is used in the production of perfumes, colognes, skincare products, deodorants, hair care, shaving products, and bath and shower products. It is suitable for use in cosmetic and personal care formulations and is often used as a raw material. It can enhance the stability of fragrances and is able to carry both essential oils and fragrance oils together.
In addition to its use in the cosmetic industry, DPG is also used in the production of plasticizers and resins, and as a solvent in paints and coatings. It has a wide range of applications due to its favourable physical and chemical properties.
Overall, DPG is a safe, odourless, and colourless organic compound that is well-suited for use in perfumes and personal care products. It effectively enhances and prolongs the scent of fragrances without altering their intended smell.

It dilutes fragrance oils and evenly distributes the scent
Dipropylene glycol (DPG) is a type of organic chemical compound that is commonly used as a solvent in fragrances. It is a clear, odourless liquid with a high boiling point and low toxicity. When added to carrier oils, DPG dilutes the strength of fragrance oils, slowly dispersing the scent. This is because DPG attaches to fragrance molecules, carrying both essential oils and fragrance oils together.
DPG is an excellent option for those looking to create long-lasting fragrances. By diluting the fragrance oils, DPG helps to evenly distribute the scent, ensuring that the perfume or cologne does not become too concentrated in certain areas. This even distribution also helps to prolong the scent's longevity, ensuring that it lingers on the skin or fabric it is applied to.
The ratio of DPG to fragrance oil can be adjusted to suit the desired strength of the final product. For example, a ratio of one part DPG to one part fragrance oil is recommended for diffuser oil, while a ratio of two parts DPG to one part fragrance is suggested for incense. When creating a fragrance oil, a simple ratio to follow is one part fragrance to two parts DPG. However, it is important to note that the recommended usage level of DPG in cosmetic applications is between 1-20%.
DPG is a versatile solvent, mixing well with most essential oils and being water-soluble. Its high purity and performance make it a popular choice for manufacturers of fragrances and personal care products. However, it is important to note that DPG is not suitable for all applications. For instance, it should be avoided in oily or waxy products due to solubility issues.

It prolongs the scent life of perfumes
Dipropylene glycol (DPG) is a type of organic chemical compound commonly used as a solvent in fragrances. It is a perfect unscented carrier oil that dilutes concentrated oils, enhancing fragrance and essential oils.
DPG prolongs the scent life of perfumes by slowly dispersing the smell. Its high boiling point and low toxicity levels make it ideal for use in perfumes and on the skin. It is also colourless and odourless, so it will not alter the appearance or scent of the perfume.
DPG is added to carrier oils, diluting the strength of fragrance oils. This slow dispersal of the smell prolongs the life of the scent. It is able to carry both essential oils and fragrance oils together, keeping perfume notes in harmony.
DPG is also used to make reed diffuser bases and incense mixtures. For diffuser oil, a ratio of 1 part DPG to 1 part fragrance is recommended, while for incense, 2 parts DPG to 1 part fragrance is suggested.

It can be used to make fragrance oils
Dipropylene glycol (DPG) is a type of organic chemical compound used as a solvent in fragrances. It is odourless, colourless, has a high boiling point, and low toxicity. Its chemical properties make it a good solvent for fragrance oils as it does not add any unnecessary odour to the final product and is safe to use on the skin.
DPG is added to carrier oils to dilute the strength of fragrance oils and slowly disperse their smell. This is why fragrance oils without DPG seem to have a shorter lifespan. It is also a good solvent as it can carry both essential oils and fragrance oils together.
To make fragrance oil with DPG, add two ounces of DPG to a non-reactive bottle or container. Then, add the fragrance oil and close the container tightly. Shake the bottle vigorously for 30 to 45 seconds until all the ingredients are well mixed. This ratio is perfect for an oil burner. If you are creating a fragrance oil mix to use on a reed diffuser, change the ratio of fragrance oil to DPG. Add three parts fragrance oil to six parts DPG. Add the fragrance oil first and then add the DPG. Shake vigorously for 30 to 45 seconds. The easiest ratio to follow when creating a fragrance oil is to mix one part fragrance into two parts DPG.
It is important to note that DPG is not a food-grade product and should not be used in food, beverage, or flavouring applications.

It can be used in incense mixtures
Dipropylene glycol (DPG) is a popular choice for incense mixtures due to its ability to effectively carry fragrances and essential oils. It is a safe and non-toxic option for skin contact, making it suitable for incense applications.
When creating incense mixtures with DPG, it is important to follow specific guidelines. Firstly, determine the desired fragrance-to-DPG ratio, typically ranging from 1:2 to 2:1. The chosen ratio will depend on the fragrance oil used and the desired strength of the incense.
Once the ratio is established, prepare the mixture by combining the fragrance oil and DPG liquid. It is crucial to stir the mixture thoroughly to ensure proper blending. The next step involves soaking the incense sticks in the scent mixture. Use a glass or HDPE plastic container to soak the sticks, and allow them to absorb the fragrance for approximately 24 hours.
After soaking, place the incense sticks on waxed paper and let them dry completely. This drying process is essential and typically takes at least 48 hours. Once the incense sticks are fully dry, they are ready for packaging or immediate use. However, it is important to note that DPG itself should not be burned as it may produce hazardous decomposition products.
By following these steps and guidelines, you can successfully create incense mixtures using DPG as the carrier for your chosen fragrances. Remember to prioritize safety and make informed decisions based on the specific materials and fragrances you are working with.
