Launching the 52nd Amendment consultation

Strengthening the IFRA Standards through science and transparency

Jennifer Dorts gives an update on the IFRA Standards, the industry’s flagship program for the safe use of fragrance ingredients worldwide.

In December 2025, IFRA launched the public consultation on the 52nd Amendment, a major milestone in the continuous evolution of the Standards. The proposed Amendment introduces 51 new Restriction Standards, revises 18 existing ones, turns the IFRA Furocoumarin Policy into a single revised Standard and removes eight outdated Standards. The consultation also covers revised guidance and annexes, reinforcing clarity and consistency.

Throughout 2026, IFRA will collect and assess stakeholder feedback, with formal notification of the 52nd Amendment expected by the end of the year.

25 years of IFRA Standards evolution

Evolving standards, science and product stewardship

Matthias Vey, Vice President, Scientific Affairs at IFRA, reflects on 25 years at IFRA and the evolution of its scientific and regulatory role. At the heart of this journey are the IFRA Standards, which for more than five decades have been central to IFRA’s mission.

Once seen mainly as a system for enforcing rules, the Standards are today widely recognized as a framework for product stewardship that supports consumer safety and responsible industry practice. Continuous scientific progress underpins this shift, with the methodologies of the Research Institute for Fragrance Materials (RIFM) evolving to reflect advances in toxicology and risk assessment. Together, these developments have strengthened the robustness, credibility and value of the IFRA Standards worldwide.

The updated IFRA Transparency List

Reinforcing insight and confidence in the perfumer’s palette

Jennifer Dorts presents the latest update to the IFRA Transparency List, often called the perfumer’s palette. The List gives a global overview of the fragrance ingredients in use at a given point in time. It is built on IFRA’s periodic Volume of Use Survey, conducted with anonymized input from Members and stakeholders.

Released in July 2025 and based on the 2024 survey, the new edition covers nearly 3,700 ingredients, including more than 1,000 Natural Complex Substances. The update reinforces IFRA’s commitment to transparency and supports the ongoing safety assessments by RIFM. The current List remains the reference until the next survey in 2028.
