Adding glycerin to perfume oil is generally not recommended. Glycerin is a humectant, meaning it attracts water molecules. In very small amounts, it can make alcohol less stinging and prevent sensitive skin from drying out. However, as a carrier oil, it will result in dampness. It is also very sticky and can cause skin and clothes to become sticky and damp. Glycerin can also cause solubility problems and negatively affect the texture of the perfume. While some sources suggest adding a maximum of 5% glycerin to slow down the evaporation rate of the perfume, most professional perfumers do not recommend its use.

What You'll Learn
Glycerin can make perfume last longer
Glycerin, a scentless base oil, can be added to perfumes to make them last longer. It acts as a fixative agent, anchoring the scent to the skin and slowing down the rate of evaporation without damaging the perfume.
Ethyl hexyl glycerin, a type of glycerin, is a good fixative that does not affect the overall odour of the fragrance. It improves the feel of the product on the skin and boosts the activity of other preservatives, thereby enabling the use of lower concentrations of preservatives in the final product.
However, glycerin should be used sparingly, with a maximum concentration of 5% of the whole mixture. This is because too much glycerin can make the perfume too sticky and affect its sprayability.
There are mixed opinions on the use of glycerin in perfumes. Some sources claim that it is unnecessary and can cause solubility problems, while others assert that it helps extend the longevity of the scent.
One formula for adding glycerin to perfume involves dividing the maximum perfume quantity by 19 ml, which can be rounded to the perfume quantity divided by 20 ml. This method applies to EDP and EDT concentrations and lower.
It is important to note that glycerin may not solve sillage issues, and some people recommend purchasing a good fragrance compound instead of using fixatives.

It is sticky and messy
While it is possible to use glycerin in perfume oil, it is generally not recommended. One of the main issues with using glycerin is that it can make the perfume sticky and messy.
Glycerin is a humectant, which means it is hygroscopic and attracts water molecules. This can lead to increased dampness on the skin and clothes, causing discomfort and an unpleasant feeling of stickiness. The stickiness can also affect the spray mechanism of the perfume bottle, making it difficult to apply the perfume evenly and causing further mess.
Additionally, glycerin has a negative enthalpy of solution, which means it is exothermic and releases heat when applied to the skin. This can lead to increased sweating and amplify the sticky sensation.
To avoid these issues, it is generally advised to use alternative ingredients in perfume-making, such as pure or near-pure fragrance materials, essential oils, and aroma chemicals. These ingredients provide better solubility and a more pleasant sensory experience for the wearer.
While glycerin can be used in very small trace amounts to extend the longevity of a perfume, it should not exceed 5% of the total formulation. Exceeding this limit will result in the perfume becoming too sticky and difficult to use.

It is not a carrier oil
Glycerin is not a traditional carrier oil. It is a non-oily emollient that can serve a similar function by carrying other ingredients. However, it does not come from the fatty portion of a plant, which is where carrier oils are derived from.
Glycerin is a humectant, which means it is hygroscopic. It attracts moisture from the air, which can lead to bacterial growth in the blend. It will also make your skin feel sticky and damp.
Glycerin can be used in very small trace amounts to make alcohol sting a little less and to prevent sensitive skin from drying out. However, it is not recommended for use in perfumes. One source says that glycerin has "no place in perfumery".
If you are looking for a carrier oil to use in perfume, fractionated coconut oil, jojoba, and grapeseed oil are all popular options.

It can make alcohol less stingy
Glycerin, or glycerol, is a sugar alcohol derived from animal products, plants, or petroleum. It is a clear, colourless, odourless, sweet-tasting, viscous liquid. Glycerin is used in many products, including pharmaceuticals, cosmetics, and food.
Glycerin is not commonly used in perfumes. However, some perfume recipes do include it as an ingredient. It is important to note that glycerin is not a fixative and will not help a fragrance last longer on the skin. In fact, it can make the fragrance sticky on the skin and create solubility problems.
Some sources suggest that glycerin can be used to replace alcohol in perfumes. Alcohol-based tinctures can have the alcohol removed and replaced with glycerin for its preserving properties. However, these products are not "alcohol-free" in a scientific or FDA regulatory sense, as glycerin contains three hydroxyl groups.
Glycerin can be used to make alcohol less stingy. This is because glycerin is a humectant, which means it helps to retain moisture. When added to alcohol, glycerin can make it less drying and irritating to the skin. Glycerin is also used to relieve constipation, as it draws water into the gut, making it a good option for reducing the sting of alcohol-induced dehydration.
Overall, while glycerin can be used in perfume, it is not a common ingredient and may not provide the desired results. It is important to experiment and see how your skin reacts to glycerin if you choose to use it in your perfume.

It is safe for the skin
Glycerin is safe for the skin. In fact, it is hygroscopic, which means it can prevent sensitive skin from drying out. However, it is not recommended for use in perfumes. This is because it is sticky and can create solubility problems.
One source suggests that glycerin can be added to perfumes to make them last longer. They recommend that glycerin should not make up more than 5% of the whole perfume, otherwise, it will be too sticky and won't spray properly.
Another source agrees that glycerin can be used to make a fragrance last longer, but only recommends using up to 5% of the fragrance formula concentrate. They also say that using too much will "flatten" a fragrance.
Despite being safe for the skin, glycerin is not commonly used in perfumery. One source says that glycerin has no place in perfumery and that common carrier oils include FCO and jojoba. Another source says that glycerin is completely unnecessary in perfumes.
Glycerin is safe to use on the skin, but it is not a common ingredient in perfumes due to its stickiness and potential to create solubility issues.
