Regulatory information
The safety of Phenylacetaldehyde has been evaluated by the Research Institute for Fragrance Materials (RIFM), with a published safety assessment. The ingredient has the potential to cause skin sensitization in a small percentage of individuals, meaning repeated contact at a sufficiently high level may trigger a temporary reaction such as redness, rash or itching for a limited number of people. To prevent sensitization, RIFM has established a maximum acceptable concentration level for this ingredient, and the International Fragrance Association (IFRA) has issued standards for its safe use in home and personal care products.
