The Swedish Society for Nature Conservation (SSNC) list farnesol as a substance causing allergies.

The European Chemicals Agency (ECHA) classifies farnesol as a substance that is very ‘toxic to aquatic life, causes serious eye irritation, causes skin irritation and may cause an allergic skin reaction’.

How is it used?

Farnesol can be found in natural pesticides and as flavoring ingredient in cigarettes. In cosmetics⋆ it is found in products such as sweet floral perfumes, essential oils, anti-aging skin care, antiperspirants, deodorants, shower creams, and other similar toiletries. In these different type of cosmetics it mainly acts anti-aging, deodorizing (to eliminate or prevent odor) and anti-microbial (to control the growth of micro-organisms on the skin). The anti-microbial properties prevents odor by actively working against microbes on the body that normally are causing odor. But the compound is not only used to hide smell, the ingredient can also be used to enhance the scent in certain products.

We use the European Commissions definition of Cosmetics:
“Cosmetics range from everyday hygiene products such as soap, shampoo, deodorant, and toothpaste to luxury beauty items including perfumes and makeup”.
