We do not exclude certain essential oils because we do not have sufficient data on their aquatic toxicity to exclude them. We note the allergens present on the ingredients list so that people who are allergic to them do not take them.
When we include essential oils, we control the dosage so as to have few allergens (generally 1 to 3, always indicated in the ingredient list on the website). We are also developing a large number of products without essential oils, particularly for sensitive skin, including our entire TEN range, which is free of essential oils, and the vast majority of our LAB serums.
