The International Fragrance Association (IFRA) has introduced the 51st Amendment to its standards, marking a significant milestone in its 50-year history. These standards are crucial for ensuring the safe and responsible use of fragrances in consumer products and are mandatory for IFRA members. The implementation timeline was communicated in the End of Consultation letter issued on April 19, 2023, with final clarifications made just before the official notification on June 30, 2023. The 51st Amendment incorporates feedback received during the consultation period and is based on peer-reviewed research and safety analysis, including input from the Research Institute for Fragrance Materials (RIFM) and the Expert Panel for Fragrance Safety. All relevant documentation is available on the IFRA website for reference.
