Everytime I post about the dangers of using synthetic fragrance oils in self care products, I get a lot of pushback from other soap and skincare makers, some accusing me of using fear to sell my products. That couldn't be further from the truth. I'm big on research and understanding before I make a claim, and there are several resources I turn to, like PubMed (National Library of Medicine), which holds countless reports and studies on the dangers of synthetic fragrance oils. One report called them "slow poisons".
Fragrance oils are made up of thousands of different chemical compounds and most are deemed safe to use. The International Fragrance Association (IFRA) makes the rules regarding safe usage levels. Yet, many studies that have emerged in recent years have concluded that consistent use of synthetic fragrances can build up in the body, causing disruption to the endocrine system, estrogen overproduction in both sexes, inflammation, suppression of the immune system, and cancer (87 fragrance chemicals are linked to cancer causing cell mutations).
Many makers like me have turned to the use of naturally derived essential oils which are mostly safe within usage guidelines, but they can also cause allergic reactions or sensitivity in some people. In that case, choose fragrance-free or scent-free products over synthetic fragrances.
I always encourage everyone to do their own research and come to their own conclusions. My goal has always been to be transparent about why I make the choices I do.
