The IFRA establishes globally recognized safety guidelines for fragrance ingredients to protect human health and the environment. These standards ensure that fragrances used in commercial and consumer products—such as perfumes, cosmetics, home fragrances, and ambient scenting—are safe for use and minimize potential risks like allergies, skin irritation, or respiratory effects. The guidelines regulate Ingredients: IFRA prohibits or limits certain fragrance ingredients that are known to cause harm (e.g., allergens, carcinogens, or endocrine disruptors). Usage: IFRA sets maximum allowable concentrations of specific ingredients in different product types (e.g., leave-on cosmetics vs. home diffusers). Exposure: IFRA establishes safe exposure levels for different applications, ensuring that airborne concentrations remain below harmful thresholds. Risk Assessments: IFRA continuously reviews new scientific data to update safety guidelines based on emerging research. Global Compliance: IFRA standards are recognised by many national and international regulatory agencies as part of their safety assessments.
