What You Need to Know About IFRA Standards in Cosmetics
IFRA standards (International Fragrance Association) provide safety guidelines for fragrance ingredients used in cosmetic products. They help ensure your formulations are safe for consumers and compliant with EU and UK regulations, including the Cosmetics Regulation (EC) 1223/2009.
If you manufacture, import, or sell cosmetics with fragrances in the UK or EU, you must comply with IFRA standards. These standards define safe usage levels for fragrance ingredients to minimise risks such as skin sensitisation, allergic reactions, or other adverse effects.
In this guide, we explain what IFRA standards are, how they classify fragrance ingredients, the latest updates, and how to ensure compliance in your products.
What Role do Fragrances and Essential Oils Play in Cosmetics?
What is a Fragrance in Cosmetic Products?
A fragrance is a blend of volatile substances and essential oils, both natural and synthetic, which create a unique aroma. These fragrances can be added to various cosmetic products, from perfumes to moisturising creams.
What Are Essential Oils and How Are They Used in Cosmetics?
Essential oils are volatile oils extracted primarily from plants (leaves, flowers, bark, etc.). They can be used pure, as in aromatherapy, or in small quantities as perfuming or active ingredients in cosmetic products.
Fragrances, essential oils, and other plant extracts often contain skin-sensitising substances. Therefore, they should be used cautiously as ingredients in cosmetic products.
What is IFRA and Why Does it Matter for Cosmetic Safety?
IFRA stands for International Fragrance Association. It is an international entity that ensures the safe use of fragrances and essential oils as raw materials. They have established a series of standards, the IFRA Standards, through which they promote the safe use of fragrances and essential oils.
How do IFRA Standards Ensure Safe Use of Fragrances and Essential Oils?
Over the years, IFRA has identified and built a database of natural and synthetic substances with the potential to be harmful to humans due to their skin-sensitising nature.
They have been monitoring and assessing the safety of these substances through the Research Institute for Fragrance Materials (RIFM), which gathers scientific data regarding the hazard potential of substances.
Based on the results, scientific evidence, and consumer feedback, the IFRA has established rules of use. These rules prohibit, limit, and/or establish purity specifications for these substances to ensure consumer safety.
To establish these rules, IFRA considered the different types of exposure that consumers may have to these substances and defined various categories according to the type of product. For each category, limits of use were established based on the composition of each fragrance or essential oil and the amount of skin-sensitising substances.
The RIFM continues to study substances with sensitising potential, and more information becomes available over time. This ongoing research leads to constant updates of IFRA standards.
Each time RIFM identifies and communicates a new concern about the safe use of a substance, IFRA issues a new standard. These standards are updated in the form of amendments, with the current amendment being the 51st Amendment.

When formulating cosmetic products with fragrances, essential oils, or other plant extracts, it is essential to adhere to IFRA standards. Request an IFRA certificate from the raw material supplier, detailing the maximum allowable quantities for the product you are developing. Ensure that the IFRA certificate is based on the current amendment.
While the European cosmetics regulation does not directly mention IFRA standards, compliance with these standards is crucial during a safety assessment of a cosmetic product. Make sure to read next our article on regulatory compliance for cosmetic products.
Ensuring that fragrances and essential oils meet IFRA standards is key to declaring the product safe. Additionally, non-compliance with IFRA standards may lead to consumer complaints related to allergic reactions, negatively affecting the cosmetic product and brand.
This is why at Taobé, we always consider this information to be very important.

Updates on Preparations for the 52nd Amendment to the IFRA Standards
With updates occurring approximately every three years, preparations for the 52nd Amendment to the IFRA standards are now underway. Consultations are expected to begin by late 2025.
