What is it?
Perfume blending follows a three-tier structure: top notes (first impression, volatile � citrus, herbs), middle/heart notes (main character � florals, spices), and base notes (lasting foundation � woods, musks, resins). The concentration determines the total fragrance load in alcohol or carrier.
How to use
Set your total volume and desired concentration (e.g., Eau de Parfum = 15-20% fragrance in alcohol). Adjust the percentage split between top, middle, and base notes. The calculator outputs precise mL for each tier and the alcohol volume needed.
Example scenario
For a 50 mL Eau de Parfum at 18% concentration with 30/50/20 split: 9 mL total fragrance oils = 2.7 mL top notes (bergamot, lemon) + 4.5 mL middles (rose, jasmine) + 1.8 mL base (sandalwood, musk). Add 41 mL of 96% perfumers alcohol.
Pro tip
Let your blend macerate (rest) for at least 4 weeks before evaluating the final scent. Top notes fade first � do not judge a perfume immediately after mixing. Use 96% ethanol perfumers alcohol, not isopropyl (IPA), which smells harsh and can alter fragrance profiles.
