Alcohol is a key ingredient in perfumes, acting as a solvent to dissolve various fragrance compounds and efficiently enhance the scent when applied to the skin. However, the type of alcohol used in perfumes is specifically denatured alcohol, which is treated to be unfit for human consumption. This denatured alcohol is typically ethanol, which is produced through the fermentation of grains and other plants, followed by distillation. The ethanol used in perfumes is usually cosmetic-grade Trade-Specific Denatured Alcohol (TSDA), with the most widely recommended variant being SD-40b. While alcohol helps create a long-lasting scent and preserve the product, it can have negative side effects on skin and hair health, including dryness, irritation, and allergic reactions. As a result, there has been a growing trend towards alcohol-free perfumes that prioritize skin health and environmental sustainability.

What You'll Learn
Ethanol vs. isopropyl alcohol
Perfumes typically use ethanol as their primary alcohol base. Ethanol is generally considered safer and less toxic than isopropyl alcohol, which is why it is fit for human consumption and is used in perfumes. Ethanol is also better tolerated by the skin and has a milder odour.
Isopropyl alcohol, on the other hand, is a synthetic alcohol made from petroleum using a chemical reaction. It is commonly referred to as "rubbing alcohol" and has a strong smell. It is also harsher on the skin. These characteristics make isopropyl alcohol unsuitable for use in perfumes.
Ethanol and isopropyl alcohol are both used in cosmetics, hand sanitisers, disinfectants, and antiseptics. However, ethanol is preferred for cleaning electronics as it is less harsh on sensitive materials. It is also more widely available in various concentrations and relatively less toxic and safer for use.
The percentage of alcohol differs between isopropyl alcohol and ethanol because their chemical properties differ, and they can be more effective against different microbes in varying concentrations. For example, isopropyl alcohol is effective against the FCV virus at 40-60% concentrations, while ethanol is more effective at 70-90% concentrations.
The choice between ethanol and isopropyl alcohol depends on the specific needs of the task at hand. Both have advantages and disadvantages, and both have diverse applications beyond electronics cleaning.

Alcohol carriers vs. oil carriers
The carrier used in a perfume will influence the length of time it lasts and the range at which others can smell it. Alcohol is the carrier of choice for fine fragrances, but natural oils such as olive oil, jojoba oil, grapeseed oil, and many others can be used as carriers for essential oils.
Perfumer's alcohol is ethanol, whereas rubbing alcohol is isopropyl alcohol. Perfumer's alcohol has less of a chemical odor, while rubbing alcohol carries a strong odor, which isn't ideal when creating aromas. Rubbing alcohol is also harsh on the skin and evaporates too quickly, so it is not used in perfumery. As far as perfumes go, the higher the proof of alcohol, the better. The more pure the alcohol, the better.
Alcohol effectively dissolves and blends essential oils and aromatic compounds in perfumes, ensuring even distribution. It also acts as a preservative, preventing microbial growth and extending the shelf life of perfumes. However, alcohol can cause irritation and dryness, especially for those with sensitive skin. Its rapid evaporation rate helps project the perfume, dispersing the fragrance from the skin. But this quick evaporation can be harsh, leaving the skin feeling dry and potentially causing irritation.
Oils, on the other hand, will keep the scent closer to the body as the oil soaks into the skin. Oil-based perfumes are moisturizing and can soften the skin. Since the oil sticks to the skin longer than alcohol, the scent will stay with you longer. However, with oil-based perfumes, what you gain in longevity, you lose in range. Only those who come in close will be able to smell your fragrance.
Both oil and alcohol are perfect carriers for aromatics, but if you prefer a more intimate fragrance experience, you may prefer perfume oils. Due to how oil interacts with the skin, the aromas incorporated into the fragrance will often unfold in a slightly different way than alcohol-based fragrances. Perfume oils also age differently, veering more into the depths of the base and middle notes over time.

Alcohol-based perfumes' advantages and disadvantages
Alcohol-based perfumes have been a crucial part of the fragrance industry for centuries. Perfumer's alcohol is a blend of ethanol (ethyl alcohol) and additives, creating a base for perfumes. It is an excellent solvent, effectively dissolving and blending essential oils and fragrance compounds, ensuring even distribution. The rapid evaporation of alcohol helps project the perfume, allowing the scent to disperse from the skin. This property makes alcoholic perfumes ideal for those looking for long-lasting fragrances with strong sillage. Furthermore, alcoholic perfumes are versatile, working well with different perfume types and facilitating layering to create unique scent profiles.
However, alcohol-based perfumes also have several drawbacks. The use of alcohol can cause skin irritation and dryness, particularly for those with sensitive skin. Alcohol strips away the skin's natural moisture and oils, disrupting the skin's ecosystem and microbiome, leading to potential skin issues and accelerated ageing. The strong scent of alcoholic perfumes may also be overwhelming for some, especially those with allergies or scent sensitivities.
In recent years, a notable shift towards alcohol-free perfumes has occurred due to growing consumer awareness of the potential health and environmental benefits of natural fragrances. Alcohol-free perfumes often contain moisturizing ingredients, providing a hydrating experience suitable for sensitive skin types. They offer a more subtle and intimate fragrance experience, allowing the scent to morph with each individual's unique skin chemistry. Additionally, natural fragrances are enriched with nourishing ingredients, capturing the essence of botanical ingredients without synthetic chemicals, resulting in a more authentic and multi-dimensional aroma profile.
When choosing between alcoholic and non-alcoholic perfumes, it is essential to consider the occasion and personal preferences for scent strength and skin comfort. Alcohol-based perfumes are ideal for those seeking long-lasting and bold fragrances, while non-alcoholic options provide a gentler and more subtle olfactory journey, prioritizing skin health and environmental sustainability.

How perfumers' alcohol is made
Perfumers alcohol is a blend of alcohol and additives used as a base for perfumes. It is used to combine with essential oils and fragrance notes to produce aromatic perfumes. The alcohol acts as a solvent, dissolving and blending the oils and compounds in perfumes, ensuring even distribution.
Perfumers alcohol is ethanol, specifically ethyl alcohol, which is often denatured to make it unfit for human consumption. This is done by adding substances such as methanol, isopropyl alcohol, or tert-butyl alcohol. The ethanol is usually at least 95% concentration, with the rest of the solution made up of water or other additives. The higher the proof of the alcohol, the better, as the rapid evaporation of alcohol helps to project the perfume and disperse the fragrance from the skin.
Perfumers alcohol can be purchased from various suppliers, with some offering USDA-certified organic products. It is important to note that not all perfumers alcohol is created equal, and some may be too diluted for effective use in perfumery.
Overall, perfumers alcohol is a key ingredient in the creation of perfumes, allowing for the simple addition and blending of fragrances to produce crystal clear solutions.
