Ingredient Glossary Compliance Deadlines & Guide for 2026

Industry urged to act now as synchronized transparency laws reshape cosmetic ingredient labeling in Beauty E-commerce.

Zurich, Switzerland – In 2026, beauty retailers across Europe and Canada will face a synchronized compliance cliff, as sweeping new regulations governing cosmetic ingredient disclosure come into force. The simultaneous enforcement of the updated INCI Glossary under Commission Implementing Decision (EU) 2025/1175 and the expanded fragrance allergen disclosure rules under Commission Regulation (EU) 2023/1545, alongside Canada’s phased implementation under SOR/2024-63, marks a turning point for ingredient transparency and supply chain accountability.

Historically, cosmetic regulation focused primarily on the safety of ingredients—banning carcinogens or restricting preservatives. The new wave of regulation, however, focuses on informational safety. The premise of Regulation (EU) 2023/1545 is not that the newly listed 56 allergens are unsafe for the general population, but that they pose a specific risk to sensitized individuals who have a "right to know". This philosophical shift places the burden of granular data disclosure squarely on the manufacturer. It is no longer sufficient for a product to be safe; its safety profile must be fully transparent, legible, and accurate down to the level of trace isomers in a complex essential oil blend.

Operational Implications for Beauty Retailers, Specialty Stores, and Department Stores:

Beauty retailers are being called upon to audit their inventories, enforce brand partner compliance, and establish centralized ingredient governance protocols.

To achieve this:

1. Brands must provide updated ingredient lists in official INCI format, not proprietary or outdated nomenclature or translations. Retailers should request allergen disclosures based on the new 81-substance list.
   
   
2. Allergens must be flagged and aggregated correctly—particularly isomer families such as “Rose Ketones” and “Citral,” which must be summed across multiple ingredients to determine threshold compliance.
   
   
3. Ingredient data must be continuously updated, verified, and made visible at the point of sale—on pack and online.
