No specific safety assessment from the Cosmetic Ingredient Review (CIR) or Scientific Committee on Consumer Safety (SCCS) has been identified. While the FDA lists it as a flavoring agent, IFRA standards impose significant restrictions on its use in cosmetic products due to documented concerns regarding dermal sensitization and potential systemic toxicity. Maximum permitted concentrations vary considerably by product category, with the most restrictive for leave-on products being 0.00064% in baby products (Category 5D), up to 1.9% in fine fragrances (Category 4).
