Fragrance allergens have become a growing concern in the cosmetic industry, particularly for individuals with sensitivities. Understanding the requirements for labeling fragrance allergens is crucial for businesses aiming to ensure compliance and safeguard consumer health. In this article, UCC will provide an overview of fragrance allergen labeling requirements, current regulations, and practical steps for businesses.

1. Overview of Fragrance Allergens and Labeling Requirements
Certain individuals may experience allergies or sensitivities to specific ingredients found in cosmetics, foods, and other products. While these ingredients are generally safe for most users, they can trigger reactions in some. Specifically, fragrance components in formulas – commonly referred to as “fragrance allergens” – may cause allergic reactions or sensitivities.
This underscores the importance of recognizing that even widely accepted safe ingredients may not suit everyone due to individual sensitivities.

2. Fragrance Allergen Labeling Requirements in Cosmetics
2.1. Key Regulations for Fragrance Allergen Labeling
The responsible party must identify and clearly specify on the label of the cosmetic product all fragrance allergens present in the product. These fragrance allergens will be determined by the FDA through specific regulations. In accordance with the provisions of the Modernization of Cosmetics Regulation Act (MoCRA), the FDA is required to:
- Issue a notice of proposed rulemaking to implement the fragrance allergen disclosure requirement no later than 18 months after the enactment of the Modernization of Cosmetics Regulation Act of 2022. Following the closure of the public comment period, the FDA will issue the final rule within 180 days.
- During the regulatory process, the FDA will take into consideration the requirements of international, state, and local entities concerning allergen disclosure, including referencing regulations in the European Union.
- The FDA may establish minimum threshold levels for fragrance allergens that must be disclosed if their concentration exceeds the specified threshold.
2.2. Timelines for Meeting Fragrance Allergen Labeling Requirements
As of July 2024, the FDA had not yet issued a draft rule for fragrance allergen labeling requirements. The agency aims to release it by October 2024 but has not committed to a specific completion date. This delay makes it challenging to meet the year-end 2024 deadline outlined in MoCRA.
To address this uncertainty, businesses can prepare by reviewing international lists of potential fragrance allergens. Checking whether your products contain these ingredients and assessing their concentrations against disclosure thresholds is a proactive step. Essential oils, in particular, may require detailed calculations to ensure accurate labeling.

3. Practical Steps for Meeting Fragrance Allergen Labeling Requirements
3.1. Review Ingredients for Potential Fragrance Allergens
To comply with fragrance allergen labeling requirements, begin by assessing the ingredients in your products. Cross-reference your ingredient list with established allergen lists from international regulatory bodies, such as the EU.
3.2. Calculate Concentration Levels for Accurate Labeling
If your products include essential oils or complex fragrances, you may need to perform detailed calculations to confirm compliance. Ensure your labels reflect any allergens present in concentrations above regulatory thresholds.

4. Important Considerations About Fragrance Allergen Labeling
Unlike food products, the FDA does not currently mandate the labeling of allergens in cosmetics. This absence of mandatory requirements creates a gap in allergen disclosure compared to food labeling standards.
If you are concerned about fragrance sensitivities, it’s advisable to avoid products containing fragrance allergens. Be sure to carefully check the ingredient lists on product labels. Opting for hypoallergenic or fragrance-free alternatives can significantly reduce your exposure to potential allergens.
