Safe usage and enjoyment of fragranced products by the consumer is enabled by a voluntarily regulated industry network of regional associations under the global remit of the International Fragrance Association (IFRA). IFRA works with the independent research organization, the Research Institute for Fragrance Materials (RIFM), to determine, implement and update the IFRA Standards, which, as one form, set maximum usage levels of restricted materials in different product types.
Since 2006, RIFM has used the quantitative risk assessment (QRA) method to determine which category of use a given product should be placed in, and therefore define the usage restrictions which should apply to that product to ensure consumer safety.
