On October 3, 2024, UK notified WTO of an addendum to the draft regulation submitted in April 2024. This addendum introduces a ban on 13 additional CMR substances (those classified as carcinogenic, mutagenic or toxic for reproduction), and updates the original transitional policies for affected cosmetic products. It is open for comments for 60 days, and scheduled to take effect on January 31, 2025, alongside the initial draft.2

Updated Transitional Provisions for Cosmetics

Compared to the initial draft, the addendum distinguishes between transitional provisions for cosmetics with newly prohibited and newly restricted ingredients. To be specific:

  • Cosmetic products containing the newly prohibited ingredients and placed on the market by April 20, 2025, can continue to be sold until October 20, 2025;

  • Cosmetic products containing the newly restricted ingredient and placed on the market by June 20, 2025, can continue to be sold until November 1, 2025.

Draft Submitted in April 2024

On April 10, 2024, UK notified WTO of a draft regulation, proposing amendments to the ingredient lists in UK Regulation (EC) 1223/2009 (Cosmetics Regulation). The draft is open for comments until June 9, 2024, and expected to be adopted on June 25, 2024.1

The proposed amendments include the addition of 52 prohibited ingredients, and 1 restricted ingredient. Notwithstanding these amendments, the draft stipulates that cosmetic products placed on the market on or before April 20, 2025, can continue to be made available on the market until August 20, 2025. The specific details of the proposed amendments are as follows:

1. List of Prohibited Ingredients: 52 added

The UK Cosmetics Regulation prohibits the use of CMR substances in cosmetics, unless an exemption has been granted by the Secretary of State. The ingredients listed in the table below are identified CMR substances regulated under Regulation 1272/2008 on Classification, Labelling and Packaging of Substances and Mixture in Great Britain (GB CLP Regulation). To uniformly prohibit these CMR substances from being used in cosmetics, this draft proposes their inclusion in the prohibited ingredients list.

2. List of Restricted Ingredients: 1 added

In October 2023, the Scientific Advisory Group on Chemical Safety of Non-Food and Non-Medicinal Consumer Products (SAG-CS) released a scientific opinion on Kojic Acid, concluding that its use at a maximum concentration of 1% in face and hand cream is considered safe. Based on this opinion, the draft proposes to add Kojic Acid into the restricted ingredients list to guide its safe use in cosmetics.
