Limonene, Linalool, Hydroxycitronellal and others
Hi, i have a weird question… Since i don’t work with fragrances much, i want to learn more. Are these components (Limonene, Linalool, coumarin… Etc.) added separately to the formula (to mask for exp) or it’s just a component of the fragrance ingredient? I know that they must be listed per the EU regulations but… you add them separately plus the FO/EO or you are given the compo from the supplier?

I would suggest doing your research off blog. While it’s easier to get a simple question with little effort, you will never gain enough deep knowledge or overall familiarity of any topic by plugging your questions in to “chatbot 1000.”
This goes for Formulating in all areas. In this day these references are even easier to reference than it was for those of us starting in the 80’s and 90’s.

believe me i am a big fan of internet, but i couldn’t find a satisfying answer 🙁 that’s why i started the post with “weird question” because i can’t seem to find an answer! where i am based, we don’t have to mention these on the label as Allergens, but we must list every single “ingredient” we put in the product, other than that we follow EU regulation. for the scented products I’ve made in the past, i just add Frangrance oils (provided by the client) and mention “fragrance” on the label, some manufacturers do the same, but some put linalool and such so i wonder, did they put it just to be more “EU compliant” or it’s a raw material in its own right.
Hope you could grasp the dilemma 😓

I have to disagree. I have 2 texts that cover these issues and I would wager I have read maybe 10 or so journal articles in the past year. The International Fragrance Association (IFRA) has lots of guidelines.
Research is key and what will in the end what will make you an effective Formulator, There are no short cuts.
The research would lead you to related issues such as MOCRA compliance, labeling, safety as well as others. For example, while these are likely part of the mandatory fragrance declaration (yet another area research would lead you to), are there cases where something like “Limonene” would be added? Those who do their due diligence already know the answer.
I’ve trained numerous techs who went on to become Chemists. One key trait was they read everything they could and I encouraged them to “stump” me. In these settings, the ones adverse to reading generally filed MSDS’s and did re-ordering until they tired of the job and moved on to other endeavors.
THERE ARE NO SHORT CUTS!

i don’t think you understand my question, It’s Ok, English is my 3rd language and sometimes it’s not perfect 😅. Thanks for your valuable advice though.

When you see an INCI like this:
That last grouping is typically (all though possible) not added as individual ingredients. As some of the preservatives that get used by the ‘natural’ folk have ended up on the naughty list. I am not an EU expert…but I do believe that part of that listing requirement…is to post them at the end.

@Graillotion Thank you!!

Those are components found in many essential oils, as well as in many fragrance oils. They may be required to have separate listing (vs only “fragrance”) by regional regulations, due to newer allergen listing requirements.
Short answer: I’d say they’re just called out for fragrance allergen listing regulations reasons.
