Cory T asks
What do you think is the upper safety level for Ylang-ylang in an oil based perfume? I have looked at the IFRA (International Fragrance Association) guideline and I’m not sure what to think about it. Thanks if you have an answer. I would appreciate it.
Hi Cory, thank you for your support! I would go along with the IFRA guideline of 0.8%. Ylang-ylang is, relatively speaking, one of the most skin-reactive essential oils. I don’t always agree with IFRA guidelines, but I think this is a good one.
