International Fragrance Association (IFRA)

IFRA sets voluntary usage standards for fragrance ingredients based on safety assessments conducted by the Research Institute for Fragrance Materials (RIFM). Each standard specifies maximum concentration limits for a fragrance ingredient based on product type (e.g., fine fragrance, body lotion, lip product). Standards are published as 'Amendments' — the IFRA Code of Practice currently reflects 50+ amendments. Compliance is self-regulated; member companies pledge to follow IFRA standards voluntarily.
