One Number on Your Fragrance Oil Label Is Killing Your Car Diffusers

I almost put $480 into a batch of car diffusers that would have destroyed my reputation. All because of one number I almost didn't check on the IFRA certificate. That number is Category 10A, and it determines whether your fragrance oil can actually throw scent in a car or whether it sits in the bottle doing nothing. In this video I break down exactly what IFRA Category 10A means, why car diffusers moved into a stricter safety category under IFRA 49, and the exact thresholds I use after testing over 100 fragrance oils. Under 18%, skip it. 18 to 25%, test one bottle first. 25% or higher, stock up (most of the time). I also cover why some makers loading at 30 to 40% still get weak throw (hint: it is not your technique, it is your oil quality), and I give you my 5-point supplier checklist and 3 suppliers I personally buy from. 🔗 FREE Fragrance Calculator.
