Benzyl salicylate is a volatile fragrance chemical with a sweet, floral odor used to scent cosmetic products and perfumes. Applied topically, benzyl salicylate can cause adverse reactions, even in small amounts. Interestingly, you can find research showing that this fragrance ingredient did not cause observable skin sensitivity under the conditions of a human skin patch test; however, this research was conducted by the Research Institute for Fragrance Materials, an independent research group supported by suppliers of fragrances and products containing fragrances. https://www.paulaschoice.com/ingredient-dictionary/ingredient-benzyl-salicylate.html?q=Benzyl%20Salicylate&fdid=ingredients
