The IFRA Standards form the basis for the globally accepted and recognized risk management system for the safe use of fragrance ingredients and are part of the IFRA Code of Practice. This is the self-regulating system of the industry, based on risk assessments carried out by an independent Expert Panel for Fragrance Safety (http://fragrancesafetypanel.org/). The Expert Panel for Fragrance Safety is an independent panel of experts that reviews the activities of the Research Institute for Fragrance Materials (RIFM). They determine safety of use for fragrance ingredients through consideration of available information and active generation of additional data. If the Expert Panel for Fragrance Safety determine that a restriction of use is necessary for consumer and environmental protection, an IFRA Standard will be published. Certain fragrance ingredients are considered safe for their use in final product application but with a defined level of impurities (e.g. traces of solvents) or reaction products or defined procedures for extraction and/or production.
