What makes a good perfumers alcohol?
Never use methanol or isopropyl alcohol for making perfume. A good perfumers alcohol will be a base of ethyl alcohol and exhibit the following properties and characteristics:
Miscibility
- Miscibility refers to two or more substances’ ability to completely mix together to create a homogenous mixture.
- Ethyl alcohol and SD40b denatured alcohol are highly miscible with fragrance oils and water.
- Adding water to 200 proof perfumers alcohol will create a solution with a new ABV. Fragrance oils that are miscible at 200 proof (100%ABV) may not be as miscible at a lower proof, which can result in foggy perfume or settling of the fragrance oil at the bottom of the perfume.
Volatility
- Volatility refers to a substance’s ability to vaporize.
- Ethyl alcohol found in food grade ethanol or SD40b denatured alcohol are both naturally volatile (evaporates easily, but not instantly).
- Volatility changes as the concentration of alcohol decreases from added water or fragrance oils.
Shelf Life
- Perfumers alcohol, before being diluted with fragrance oils, does not expire.
- Adding fragrance oils or water to your perfume may alter the shelf life of your final perfume recipe, every fragrance oil is different there is no stead fast rule to offer here other than be aware a change may occur.
- Store unused perfumers alcohol at full strength or blended with water in the original bottle it was shipped in.
- Store finished perfume in a cool dark place, out of direct sun light, away from children and pets, and always with the cap tightly sealed.
- Atomizers and misters may not be as air tight as they look, they may be more susceptible to loss due to temperature changes of the liquid.
Base Aroma
- Perfumers alcohol base should have a "sensation" of alcohol, but should not "smell" of anything specific.
- Food grade alcohols made from different raw ingredient bases have different aromas, even at 200 proof, and perfumers should understand the differences presented by each before buying discount organic cane alcohol.

- Denaturants, depending on their source or specific origins, may contribute their own aroma/odor to the base alcohol and should be considered.
Does Certified Organic matter for Perfume?
Finally, there are options and choices for perfumers that are best for our body and planet. Products offered as organic must meet strict quality and chain of custody requirements, however not everyone requires certified organic ingredients for their final product. If you are offering an organic perfume, cologne, or body product, sourcing USDA certified organic alcohol is key to maintaining your product's complete organic certification. If a product is labeled as denatured, it is unlikely to be granted USDA certified status.
Denatured vs Pure Alcohol for Perfumers
All products labeled "perfumers alcohol" for sale online should contain only "ethyl alcohol" (ethanol). Some products available online, even if listed as "200 Proof Perfumers Alcohol" may still contain additives or "denaturants".
If denaturants are toxic, why use them at all?
Because of the reduced cost of denatured ethyl alcohol vs tax-paid undenatured ethyl alcohol, denatured blends like SDA40b are used throughout the commercial perfume making industry.
Many perfumers have grown accustomed to using denatured alcohol for their perfume recipes, or unaware that a better, more pure alternative exists in food grade ethyl alcohol.
Does Food Grade Ethanol make for a good Perfumers Alcohol?
Yes. Food Grade Ethanol refers to pure ethyl alcohol, identical to what's used in SD40b denatured alcohol blends but devoid of any harmful additives. It's completely safe for consumption and topical use, making it the superior choice for creating perfumes.
