My wife has fallen in love with a fragrance in a soap she tried. I know the oils and percentages used, but am not completely clear on how to make a perfume. Trying the Google leads me to a good number of "how to make homemade perfume" websites that are all different, and all questionable. I *think* I understand the guidance provided by the FO supplier as it applies here. Say I am going to use 75% of FO #1 and 20% of FO #2. Both are listed on Nature's Garden website as 5% use max in perfume and lotions. So the math is easy ... 5% max. The big question is: what makes up the remainder? Is a perfume just fragrance + carrier oil? Or is there a percentage of alcohol like in a man's after-shave or cologne? The next question of course is what oil? I've found references for jojoba, apricot oil, almond oil, avocado oil, and coconut oil (fractionated I assume) among others. Are there any real differentiators here? I realize this is semi off-topic for this forum, but I'm sure someone here might be able to at least point me to a reputable reference.
