Science and research are the foundations of the IFRA Standards.

Whether an ingredient comes from nature or is created in a laboratory, it faces the same rigorous testing process, based on scientific evidence and our deep understanding of how people use fragranced products.

Teamwork underpins the development of the IFRA Standards, using a system based on long-term collaboration involving scientists, medical professionals, public authorities and the industry.
