Hi Stephanie, I don’t have a perfume making advice question as much as a simple yes or no question. Can the 100% cologne oil knockoffs that you can buy from places like thecommonscents.com and haywardenterprises.com be mixed with alcohol to create an edp or edt? I have no idea about perfume making, but was curious if this was the only step that is needed to make the product a spray. I can’t find the answer anywhere. thanks for the help if you can answer. I look forward to your site.
Chris, this is a great question. Only the answer is more of a “Yes, but…”
It depends on the product that’s being sold, and it takes some reviewing of the wording to determine if they are really uncut fragrance or ready-to-wear. In perfume terms, “Perfume” and “cologne” designate certain concentrations of fragrance (like EDP and EDT), but a vendor could also use those words and simply mean male and female fragrances.
If the fragrances are finished and marketed for wearing out of the bottle, they will be in a carrier. Carriers are the bases that fragrances are blended into to put them at a skin safe concentration. Common carriers are alcohol aka ethanol, natural fixed oils like jojoba, sweet almond oil, and sunflower oil, or other carriers like DPG, mineral oil and silicones. Fixed oils (as opposed to volatile oils that evaporate) will not blend with alcohol, and the others types may blend partially or not at all.
Many sites sell pure uncut fragrance oil and say it’s ready to wear, but I would never recommend wearing undiluted. That’s about 300-400% more than a normal concentration for skin wear, and you could possibly become allergic to the frag components.
If the scents in question are fragrance oils like these that are intended for soapmaking and multiple cosmetics types, then they would be uncut and they should blend completely into alcohol.
Also as a side note, if you are working with a raw aromatic material like a natural resin, often it will not blend fully but you’re not as likely to encounter that when purchasing fragrance oils prepared for the market.
