British authorities have notified the World Trade Organization (WTO) of a proposed amendment to the cosmetics regulations applicable in Great Britain, which introduces significant changes regarding ingredients. The amendment affects both the restriction of certain substances and the expansion of the list of ingredients prohibited by their CMR classification.

New conditions for hexyl salicylate
One of the most notable aspects of the proposal is the introduction of usage limits for hexyl salicylate , an ingredient widely used in perfumery and cosmetic formulations.
Until now, this substance was not subject to specific restrictions under British cosmetic regulations. However, its classification as a skin sensitizer and a reproductive toxicant (category 2) has led authorities to establish differentiated usage conditions depending on the product type, including rinse-off products, leave-on products, and formulations intended for infants.
The proposal also includes transitional periods, allowing the marketing for a limited time of products already introduced into the market before the new restrictions come into force.
Expansion of the list of prohibited CMR substances
In parallel, the amendment provides for the inclusion of new substances classified as carcinogenic, mutagenic or toxic to reproduction (CMR) in the annex of prohibited ingredients.
This type of update responds to the strict application of the consumer safety principle, reinforcing the exclusion of ingredients whose hazard profile is not compatible with continued cosmetic use.
The full list of substances affected by this amendment can be found in the official document notified to the WTO, available at the following link
In summary
The notification issued by the United Kingdom anticipates further regulatory adjustments regarding cosmetic ingredients, confirming the evolution of the British regulatory framework following Brexit. Although the proposal is still in the consultation phase, it represents a key reference point for monitoring future obligations applicable to the UK market.
