Created in August 2023 and taken into effect in 2025, amendment 51 introduced 48 new restrictions/eliminations of various synthetic aroma chemicals frequently used in fragrance.

Most notably new restrictions were placed on Iso-E-Super, Coumarin, Aldehydes, Limonene, Geraniol, Citronellol and the removal of Benzyl alcohol and Benzyl Salicylate.

As an example Iso-e-super is a widely used note in fragrances, such as terre d'hermes, Dior Homme 2021 and Hermes EAU Givree.

*You can recognize this recall if you have a shorter ingredient list on the box and check the batch code on a website.

• A Reddit user by the name of SarvGarg made an excellent easy to understand article about Amendment 51, I reposted it on my server here.

*It's important to note that some independent niche brands and middle eastern brands may not adhere to these changes immediately. However, if a brand is acquired by a larger corporation or they want to attain a stronger mainstream distribution, compliance with these guidelines may become necessary. Ex: both Tom Ford and Frederic Malle we purchased by Estee Lauder, etc.
