0.05% Fragrance in products
I decided to discontinue use of almost all fragrances and essential oils except for one leave in hair product and one conditioner. Could this still cause irritation for customers with sensitive skin?

Well, for some consumers ANY ingredient in your formula could cause sensitivity. It’s just that there are more ingredients in the fragrance that could cause the problem for more consumers. But it is generally true that the lower you go in fragrance, the less exposure people get, and the less chance that they will experience a problem.

It depends on the fragrant material (aroma chemicals) you’re using. To be on the safe side, avoid formulating with essential oils and IFRA allergens, which are the ingredients you’d have to specify in the INCI list on your product like Citral, Limonene, Linalool, Cinnamic Alcohol etc.
As I’ve also been making perfumes for cosmetics and as EDT/EDP fragrances for over a decade now, I can help you with that if you request. Already made a few hypoallergenic ones for baby products.

Thank you! I had little choice but to use fragrance oils for a few products, but two are wash off and one is leave on but for hair. Since technically the fragrances only touches the hands briefly and possibly the hair could get on skin if its someone with long hair but research said zero fragrance is safe and .05% (1-2 drops in x amt of product i made) was still too much. I’m trying to reformulate to zero fragrance but some “natural” ingredients smell awful or look awful. I cater to the “natural” audience because most don’t know the ins and outs of what natural is and when put to the test, they actually do not like natural lol. Even when it performs better. I’ve been using isolates but I’ve lost the COA, I’ve been avoiding the top allergens but can’t say if any snuck in since the list is very long. I’ve been using chatgpt to copy and paste so that can help. Otherwise, I was hoping for now .05% can still be listed as sensitive.

IFRA always puzzled me, since their evaluations seem to be more loose. Let me put an example: cinnamic aldehyde according to IFRA for the category 9 (shampoos and soaps), can be present up to 0.49% in the finished product (quite high frankly for a known allergen). On the other hand, for Cosing (or the EU), the same allergen should be declared at concentrations above 0.01% for the same category of products. While the EU doesn’t ban the allergen, that you have to label it above 0.01% make fragrance companies to at least use that ingredient with some caution (theoreticaly, under IFRA you could have a shampoo fragrance purely made with the allergen and comply with their regulation). That also reminded me why IFRA opposed to the release of the 82 allergen new list from the EU, back in the day.
