Methyl salicylate, a compound widely used in cosmetic products for its aromatic and analgesic properties, has been subject to new regulatory restrictions in the UK. The recent update to the Restriction of Chemicals in Cosmetic Products Regulations 2025, announced by the Department of Business and Trade, introduces stricter limits on its use in various formulations, with the aim of strengthening consumer protection.

The regulatory framework and its impact on the cosmetics industry
On 30 April 2025, the United Kingdom brought into force the amendments to Regulation (EC) No 1223/2009 , inherited from the European regulations after Brexit. The main reason behind this adjustment is the classification of methyl salicylate as a CMR Category 2 substance (Carcinogenic, Mutagenic or Toxic for Reproduction), which has led to a re-evaluation of its safety in cosmetic products.
The decision is based on studies by the UK Scientific Advisory Group on Chemical Safety, which considers it safe to use within certain concentration limits.
Main restrictions and permitted gatherings
The new restrictions affect a wide range of cosmetic products. Below are the main changes in terms of maximum permitted concentrations:
Rinse aids (except hand soaps)
0.02% on products intended for children aged 0.5 to 1 year .
0.06% on products for children over 1 year old and adults.
Hand soaps
0.02% for children from 0.5 to 1 year old .
0.6% for children over 1 year old and adults.
Leave-in skin products
(except facial makeup, aerosol deodorants and hydroalcoholic fragrances):
0.02% on products for children from 0.5 to 1 year old .
0.06% on products for people over 1 year of age and adults.
Lipsticks and lip balms
0.02% for children from 0.5 to 1 year old .
0.03% for children over 1 year of age and adults.

.
Transition and compliance period
To avoid a drastic impact on the industry, a transition period has been established that will allow the sale of products with the current formulation until March 31, 2026, provided that they have been marketed before September 30, 2025.
A necessary adjustment for consumer safety
New restrictions on methyl salicylate in cosmetics reinforce the UK’s commitment to consumer safety. While these regulations can be a challenge for manufacturers, they also represent an opportunity to reformulate products and adapt to an increasingly regulated market.
Since the European Union is also considering similar changes , it is possible that both regulations will converge in the future, thus avoiding regulatory discrepancies between the British and European markets.
