Isopropyl alcohol, also known as rubbing alcohol, is not recommended for perfume-making due to its strong and distinct bitter odour that lingers even after evaporation. It is harsh on the skin and may interfere with the dissolution of raw materials in the perfume mixture. However, some people experiment with using isopropyl alcohol for basic fragrance tests or in very small concentrations, as it evaporates quickly, leaving no traces. For perfume-making, perfumer's alcohol, which contains ethanol, is typically used as it creates a perfect balance of absorption and evaporation for fragrance mixtures.

What You'll Learn
Isopropyl alcohol has a strong smell and is harsh on the skin
Isopropyl alcohol, also known as rubbing alcohol, is not suitable for use in perfumes. This is because it has a strong smell and is harsh on the skin.
Isopropyl alcohol has a distinct bitter odour that never truly disappears, no matter what other substances are mixed with it. One source claims that the smell of isopropyl alcohol is so strong that it will affect the rest of the perfume composition, even after sitting for a few days. Another source states that while the smell of isopropyl alcohol evaporates quickly, it is still very pungent.
Isopropyl alcohol is also harsh on the skin. This is because it contains a very high percentage of water, which can interfere with the perfume. Some sources claim that materials do not dissolve well in isopropyl alcohol, which is a key function of perfumer's alcohol.
Perfumer's alcohol, on the other hand, is a blend of alcohol and additives used as a base for perfumes. It is typically made with ethanol, which is much more suitable for combining with essential oils and fragrance notes to produce aromatic perfumes. Ethanol is commonly used in spray-on perfumes, as it has a good balance of absorption and evaporation. It is also safe for the skin, unlike isopropyl alcohol.
Overall, isopropyl alcohol is not suitable for use in perfumes due to its strong smell and harsh effects on the skin. It is important to choose a safe and suitable alcohol, such as ethanol, when creating perfumes to ensure the best results and avoid any skin irritation.

It is a good solvent and disinfectant
Isopropyl alcohol, also known as rubbing alcohol, is a good solvent, especially in high concentrations. It is an excellent disinfectant and works well for eliminating body odours. It has a very fast evaporation rate, leaving no traces of its harsh smell.
Isopropyl alcohol is a chemical compound with the formula C3H8O3, or CH3CHOHCH3. It is a colourless, flammable liquid with a strong odour. It is commonly used as a solvent and as a disinfectant. It is effective at eliminating bacteria, viruses, and other microorganisms. Due to these properties, it is often used in cleaning solutions and hand sanitizers.
When used in perfumes, isopropyl alcohol can help to eliminate body odours and provide a clean base for the fragrance. It is important to note that isopropyl alcohol should only be used in very small concentrations in perfume-making, as it has a strong and bitter odour that can be harsh on the skin. This odour does not dissipate over time, even when mixed with other fragrances. Therefore, it is not ideal for perfumery and can interfere with the final scent.
Some people have experimented with using isopropyl alcohol in their homemade perfumes. They have found that while it does not affect the scent of essential oils, it does not make the fragrance last longer. Isopropyl alcohol is also not suitable for dissolving raw materials, as it contains a high percentage of water.
Overall, while isopropyl alcohol is a good solvent and disinfectant, its strong odour and potential skin irritation make it less suitable for perfume-making. It is important to use safe and non-toxic ingredients when creating fragrances to avoid any adverse reactions.

It is not suitable for perfumes because raw materials do not dissolve into it
Isopropyl alcohol, also known as rubbing alcohol, is not suitable for making perfumes. This is mainly because it has a strong, bitter odour that never really goes away, even when mixed with other scents. It is also harsh on the skin and can cause irritation.
Another issue with using isopropyl alcohol as a base for perfume is that raw materials do not dissolve into it. This is due to the fact that rubbing alcohol contains a very high percentage of water. Water can interfere with perfumes as it can cause cloudiness in the fragrance due to the formation of a colloid. If water is added to a perfume, it must be deionised or distilled—regular tap water will not suffice.
Perfumers often use ethanol or perfumer's alcohol as a base for their fragrances. These types of alcohol create a perfect marriage of absorption and evaporation, which is ideal for mixing. Ethanol is found in alcoholic drinks, biofuel, and perfume. It is also commonly known as "alcohol" in everyday life. Perfumers often use high-proof, food-grade ethanol, which is easy to obtain.
Some people also use vodka or Everclear as a base for their perfumes. These are clear and do not have a particularly "boozy" odour. It is important to note that toxic oils, such as thyme and cinnamon, should be used sparingly as they can be harmful in high doses.

It is not ideal for perfumes as it contains added water
Isopropyl alcohol, commonly known as rubbing alcohol, is not ideal for making perfumes. This is mainly because it contains added water, which can interfere with the final product.
Firstly, the presence of water can affect the scent of the perfume. While some perfumers add a small amount of water (only a couple of per cent) to make the fragrance less harsh on the skin and to help 'lift' the scent, it can also cloud the fragrance due to the formation of a colloid.
Secondly, the added water in rubbing alcohol can cause issues with dissolving raw materials. This is because isopropyl alcohol is a poor solvent for many of the ingredients used in perfumes.
Thirdly, isopropyl alcohol has a very distinct bitter odour that never really goes away, no matter what you mix into it. This can negatively impact the overall fragrance of the perfume.
Finally, isopropyl alcohol is harsh on the skin, which is not a desirable trait for a perfume intended for topical application.
In summary, while isopropyl alcohol may be used in very small concentrations in certain applications, it is generally not ideal for perfumes due to the presence of added water and its strong odour, poor solvent properties, and skin irritation potential.

Ethanol is a better alternative for perfumes
Isopropyl alcohol, also known as rubbing alcohol, is sometimes used as a substitute for ethanol in perfumes. However, it is not ideal due to its distinct bitter odour that never really goes away, no matter what you mix into it.
Ethanol, on the other hand, is a better alternative for perfumes for several reasons. Firstly, it has a neutral odour and will not interfere with the scent of the perfume. It is commonly used as a solvent to create a sprayable consistency and help the perfume disperse well on the skin and evaporate. It is also safer for the skin than isopropyl alcohol, which can be harsh and irritating.
Another advantage of using ethanol is its wide availability. Ethanol can be easily sourced from alcoholic beverages or grain alcohol, such as Everclear, which has a high proof and is suitable for perfumery. It is also commonly used in the cosmetic industry, making it a reliable and accessible option for perfume makers.
Furthermore, ethanol is effective at preserving and carrying fragrance compounds. It is often used to dilute fragrance concentrates made from aromachemicals and essential oils, creating a stable and long-lasting perfume.
While isopropyl alcohol can be used as a disinfectant and solvent in other applications, its strong smell and skin irritation make it unsuitable for perfumes. Ethanol, with its neutral odour, skin-friendly properties, and wide availability, is the preferred choice for creating high-quality, safe, and appealing perfumes.

Frequently asked questions
No, isopropyl alcohol is not suitable for use in perfumes as it has a strong, bitter smell and is harsh on the skin. It also contains added water which can interfere with your perfume.
You should use perfumer's alcohol, which is a blend of alcohol and additives used as a base for perfumes. Perfumer's alcohol contains ethanol, which is commonly used in perfumes.
Ethanol is a specific type of alcohol formed when an ethyl group is added to the alcohol molecule. It is commonly found in alcoholic drinks, biofuel, and perfumes.
Perfumer's alcohol acts as a carrier for the scent, diluting essential oils and fragrance ingredients to reduce potential harm to the skin. It also creates a balance between absorption and evaporation, influencing how long a perfume lasts and how far its scent reaches.
Yes, alternatives such as vodka or Everclear (pure 190-proof alcoholic beverages) can be used. These alternatives are clear and do not have a strong odour that interferes with the perfume's scent. However, it is important to avoid using toxic carrier oils and denatured alcohol or methanol when creating perfumes.
