    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.
