EU Cosmetic Fragrance Allergen Labeling 2026: Preparing For The New Disclosure Requirements

How Regulation (EU) 2023/1545, Fragrance Allergen Labeling, CPSR, PIF, IFRA Compliance, and Regulatory Readiness Are Transforming Cosmetic Compliance in the EU

From 31 July 2026, Commission Regulation (EU) 2023/1545 significantly expands the fragrance allergen labeling requirements under the EU Cosmetics Regulation (EC) No. 1223/2009.

The number of fragrance allergens that must be individually declared on cosmetic product labels will increase from 24 to more than 80, marking one of the most significant labeling changes for the cosmetics industry in recent years.

For cosmetic manufacturers, fragrance houses, brand owners, importers, and Responsible Persons, this is more than a labeling update it requires a comprehensive review of formulations, safety documentation, supplier information, and compliance processes to ensure products remain market-ready across the European Union.

Why This Regulatory Change Matters

The new allergen disclosure requirements are designed to improve consumer transparency and better protect individuals with fragrance allergies by providing more detailed ingredient information.

Beginning 31 July 2026:

• All new cosmetic products placed on the EU market must comply with the updated allergen labeling requirements. 
• Cosmetic products already placed on the market before the deadline may continue to be sold until 31 July 2028 under the transitional provisions. 

Failure to comply may result in:

• Non-compliant product labeling 
• Market withdrawal or recalls 
• Regulatory enforcement actions 
• Delayed product launches 
• Increased compliance costs 
• Supply chain disruptions 
• Re-labeling and reformulation expenses 
• Reputational risk 

Executive Overview

The new requirements affect them much more than product labels.

A future-ready fragrance compliance program should be:

• Regulatory complaint 
• Consumer-focused 
• Scientifically supported 
• Risk-based 
• Inspection ready 
• Well documented 
• Globally aligned 
• Lifecycle managed 
• Supported by regulatory intelligence 
• Continuously monitored 

Organizations that begin preparations early can minimize business disruption while maintaining market access across Europe.

Understanding Regulation (EU) 2023/1545

The Regulation amends Annex III of the EU Cosmetics Regulation by expanding the list of fragrance allergens that require individual disclosure on cosmetic labels.

The updated requirements apply across all EU Member States and Northern Ireland.

The objective is to improve consumer awareness by ensuring that individuals with fragrance allergies can more easily identify substances that may trigger allergic reactions.

New Labeling Requirements

Products containing listed fragrance allergens above specified thresholds must identify each allergen individually on the product label.
