The International Fragrance Association (IFRA) is a global body that represents the fragrance industry. It was established in 1973 and has over 160 members worldwide, including fragrance houses, suppliers, and associations. IFRA has developed a set of guidelines to ensure the safe use of fragrances, known as the IFRA Standards. These standards are based on extensive research and testing to determine the safe levels of fragrance ingredients, and they apply to all types of fragrances, including fine fragrances, personal care products, household products, and air care products. The IFRA Standards ban, limit, or set criteria for the use of certain ingredients, and these criteria are typically provided as a percentage. This percentage represents the maximum safe use level for a particular fragrance ingredient in a specific product type. For example, the IFRA rate for 8th & Ocean fragrance oil is 0.07% in lotion, 31.75% in soap, and 100% in candles. These rates ensure that fragrances are not only pleasant but also safe for consumers and the environment.

The IFRA Standards ban, limit, or set criteria for the use of certain ingredients, based on scientific evidence and consumer insights. The system is demanding and aims to offer a great degree of protection to the majority of the population. The standards set out the maximum safe use levels for individual fragrance materials in different product types, including fine fragrances, personal care products, household products, and air care products. There are three main types of standards: Prohibited, Restricted, and Specification. These standards define the permitted usage levels or restrictions for fragrance ingredients in various product categories to ensure consumer safety.
The IFRA Transparency List is a key tool that provides information about the ingredients used by IFRA members worldwide. It includes fragrance ingredients, which are substances used for odor or malodor coverage, and functional ingredients, which are essential for the functionality or durability of a fragrance compound. The list is based on reporting provided by IFRA members in the 'Volume of Use Survey', which is compiled approximately every five years. The latest list, published in 2022, provides a snapshot of the ingredients used by fragrance companies around the world.
The IFRA rates help determine the safe amount of fragrance oil that can be used in a product. These rates are typically given as a percentage and can vary depending on the product type. For example, the IFRA rate for 8th & Ocean fragrance oil is 0.07% in lotion, 31.75% in soap, and 100% in candles. It's important to note that the IFRA rates are just recommendations, and you may use more or less than the recommended maximum percentages. However, if you plan on using a higher percentage of fragrance, it's crucial to research the toxicity levels of the particular fragrance oil and consult with a third-party professional or a certified chemist to ensure safe usage.

The IFRA Standards apply to all types of fragrances, including fine fragrances, personal care products, household products, and air care products. The three main types of standards are Prohibited, Restricted, and Specification. These standards define the permitted usage levels or restrictions for fragrance ingredients in various product categories to ensure consumer safety. For instance, prohibited standards refer to fragrance ingredients that are not allowed to be used in specific product categories as they pose significant risks to human health or the environment. Specification standards, on the other hand, apply to fragrance ingredients with specific chemical criteria, defining the purity and composition requirements to ensure the safety and reliability of fragranced products.
The IFRA Transparency List is a key tool used by the IFRA to provide information about the ingredients used by its members worldwide. This list includes fragrance ingredients, which are substances used for odor or malodor coverage, and functional ingredients, which are essential for the functionality or durability of a fragrance compound. The list is based on reporting from IFRA members in the 'Volume of Use Survey', conducted approximately every five years. The latest list was published in 2022, providing insight into the ingredients used globally in the fragrance industry.
The IFRA Standards are constantly updated to stay aligned with the latest scientific knowledge and safe use requirements. IFRA achieves this by continually evaluating new scientific research to identify and manage potential risks associated with certain fragrance ingredients. These amendments might involve restricting or banning the usage of specific materials that could trigger allergies or sensitivities. For instance, IFRA documentation provides maximum usage percentages for different product variations, such as 0.07% for lotion and 31.75% for soap when using the 8th & Ocean fragrance oil. These rates are essential for determining the safe use of fragrances in different applications.

IFRA's three main types of standards: Prohibited, Restricted, and Specification
The International Fragrance Association (IFRA) has developed a set of standards to ensure the safe use of fragrances. These standards are based on scientific research and risk assessments conducted by independent experts. The three main types of IFRA standards are:
Prohibited Standards
Prohibited standards refer to fragrance ingredients that are not allowed to be used in specific product categories. These ingredients have been identified as posing significant risks to human health or the environment, and their use is strictly forbidden. For example, Mintlactone (CAS 13341-72-5) has been deemed unsafe and is prohibited from being used as a fragrance ingredient. The Prohibited standards prevent the inclusion of harmful substances in consumer products, ensuring the safety and well-being of consumers.
Restricted Standards
Restricted standards specify the maximum permitted usage levels of certain fragrance ingredients in different product categories. These limits are established based on scientific assessments and toxicological studies to ensure consumer safety. Restricted standards aim to manage and control the potential risks associated with fragrance ingredients without entirely prohibiting their use. For instance, a fragrance oil with a safety rate below 5% should be used in accordance with IFRA guidelines to avoid irritation.
Specification Standards
Specification standards apply to fragrance ingredients for which specific chemical criteria are set. These criteria define the purity and composition requirements of the ingredient used in fragrance formulations. By enforcing strict specifications, the IFRA ensures that manufacturers use only high-quality and consistent materials, promoting the safety and reliability of fragranced products. Specification Standards are established when toxicological effects are linked to impurities within a material, rather than the material itself. In such cases, limits or restrictions are set for these impurities to safeguard human health and the environment.
These three types of standards work together to define the permitted usage levels and restrictions for fragrance ingredients in various product categories, ensuring consumer safety and maintaining a level playing field within the fragrance industry. The IFRA Transparency List provides an overview of the ingredients used by fragrance companies worldwide, helping to provide information and build tools for members and consumers.

IFRA Transparency List provides an overview of ingredients used in fragrances
The IFRA Transparency List is a comprehensive overview of the ingredients used in fragrance mixtures by consumer goods companies. It is a tool that helps to ensure the safe use of fragrances and is part of the fragrance industry's commitment to transparency. The list is based on reporting from IFRA members in the 'Volume of Use Survey', which is compiled approximately every five years. The latest list, published in 2022, includes 3,619 ingredients, comprising 3,224 fragrance ingredients and 395 functional ingredients.
Fragrance ingredients are substances used for odour or malodour coverage. Functional ingredients, on the other hand, are substances essential for the functionality or durability of a fragrance compound, such as antioxidants, preservatives, diluents, solvents or colours. These functional ingredients have a much broader use outside the fragrance industry and are therefore not evaluated in the RIFM Safety Assessment Program. Instead, they are classified as functional ingredients and removed from the program.
The IFRA Transparency List is significant as it provides a snapshot of the ingredients used by fragrance companies worldwide, including those used in minimal quantities or only in certain countries or regions. This list is not just for the fragrance industry but also for consumers, helping them understand the ingredients used in fragranced products and make informed choices. The list is also used to develop tools and services for IFRA members, such as the IFRA Fragrance Ingredient Glossary.
The IFRA Standards, which the Transparency List supports, aim to ensure the safe use of fragrances. These standards are developed in partnership with members and stakeholders, overseen by independent experts. They ban, limit or set criteria for the use of certain ingredients, based on scientific evidence and consumer insights. The IFRA Standards are recognised by government authorities and trade bodies worldwide, and IFRA members, who produce around 80% of the global volume of fragrances, must comply with them.

IFRA rates vary depending on the product, e.g., lotion, soap, candles, or perfumes
The International Fragrance Association (IFRA) was formed in 1973 to promote the safe use of fragrance oils. IFRA standards are based on scientific evidence and consumer insights to determine which ingredients can be used in fragrance formulations, as well as safe-usage limitations for these ingredients.
IFRA rates vary depending on the product, such as lotion, soap, candles, or perfumes. For instance, the 8th & Ocean fragrance oil can be used at 0.07% in lotions, 31.75% in soap, and 100% in candles. However, the typical use rate of fragrance in candles is around 10%. This is because the IFRA rate is a safety rate, and using 100% fragrance oil in candles would be unsafe.
The IFRA documentation categorizes different products, with Category 4 being lotions and leave-on products, Category 9 being soap, bath bombs, and rinse-off products, and Category 11 being candles and all non-skin contact products. Fragrance oils with a safety rate below 5% should be used with caution, as per IFRA guidelines, to avoid irritation.
It is important to check the IFRA statement for each fragrance oil to ensure safe usage, as some fragrance oils may have a very low percentage allowed for products like shampoo or lotion, but allow a higher percentage for bar soap or perfume. While many fragrance oils are skin-safe, not all are approved for skin use, so it is crucial to check the IFRA certificate before use.
