They need to be used safely, this website is a good source of information. https://tisserandinstitute.org/safety-guidelines/

I avoid them almost entirely (I only use Blue Tansy in one of my products, mostly for color.)
Let’s just say they are “high risk.”
You have to be very careful. The citrus essential oils can be phototoxic, and for example, lavender essential oil has been found to be cytotoxic.
You have to have a really reliable supplier if you’re going to use essential oils, and you have to be careful in your handling of them as well. You should never have skin contact with 100% essential oil, for example.

In the hands of a skilled formulator who knows and understands essential oils, I would rate them as safe.Also, sourcing plays an important role, as do proper CoAs, and a formulator who understands the information provide. The allergens analysis in a CoA is important.The fact is that EOs have been around a long time, and are well documented in the scientific literature.And the alternatives? Synthetic fragrances. -

I will paste an example below…from my supplier. Does that mean that the TWO items that are listed, those are the probable allergens of the the 67 constituents in that EO?
If so, I did not know that before.

I believe this C of A list is the percentage of each terpenoid which is a representation of the olfactory characteristic of this essential oil, not an allergen analysis.

Thank you Syl, Graillotion, Markethair, emma1985.

In EU there is a list of 26 allergens you have to declare on LOI if the product contains more then 0,01% (in leave on). I normaly ask for a List of allergens separately cause not all companies put it on the CoA.
I´m not sure why Eugenol is listed twice there on your CoA. To my knowledge Beta Carophyllene is not listed as allergen yet. -
A lot on EOs was discussed here:https://chemistscorner.com/cosmeticsciencetalk/discussion/4656/to-be-or-not-to-be-essential-oils-in-skincare#latest
plus Perry kindly shared additional read (available to be downloaded)

As Ilse pointed out - the CoA is confusing. Eugenol is both 75% and 7%. Ask the supplier for clarification.
Eugenol is among the Fragrance allergens that require cosmetic/detergent labeling.

Yes, I chose the clove CoA, due to the fact it has a known allergen. But was puzzled with the double listing.
Where can I see…or can someone link the 26 allergens for the EU that @Ilsme referred?
-
doesn’t offer a lot of confidence on that supplier.
-
I would ask the supplier to explain this and to give you the information on the list of allergens and the IFRA Conformity Certificate. The later states what is the max concentration you can safely use in your product. Every supplier should be able to give you this information.

I´m not sure why Eugenol is listed twice there on your CoA. To my knowledge Beta Carophyllene is not listed as allergen yet.The Eugenol is not listed twice. The 60 - 95% is the expected range of results, and the 74.70% is the measured result.Sometimes it’s a case of the blind leading the blind. Customers who don’t understand these documents, and the same applies to ingredient suppliers. -
@mikethair what does Eugenol content means 1-9% result 7.09 when it was mentioned before as being 74.70%. I should call them and ask, they are located in Toronto Canada.

There is Eugenol and Eugenol content (bellow beta-caryophyllene) with two different ranges and different results. If there´s a reason for that I would like to know, as I have not seen that on any ohter CoA of ingredients I work with (essential oils among them).
