UK Implements Ban on 64 Harmful Substances and Limits Kojic Acid in Cosmetics

On December 17, 2024, the UK government announced new cosmetic safety regulations under Statutory Instrument 2024 No. 1334. These changes include banning 64 substances classified as Carcinogenic, Mutagenic, or Reprotoxic (CMR) and imposing stricter rules on the use of kojic acid, a popular ingredient in skin-brightening products.

Prohibited Substances

Eight of the banned substances already appear on the EU’s list of prohibited ingredients. These include:

Methylene di-t-Butylcresol (CAS 119-47-1)
MIBK (Methyl Isobutyl Ketone) (CAS 108-10-1)
Benzophenone (CAS 119-61-9)
Theophylline (CAS 58-55-9)
Trimethylolpropane Triacrylate (CAS 15625-89-5)
Azadirachta Indica Seed Extract (CAS 84696-25-3)
Melamine (CAS 108-78-1)
Dimethyltolylamine (CAS 99-97-8)

The ban will apply to new cosmetic products starting April 20, 2025, and any existing products containing these substances must be removed from the market by October 20, 2025.

New Limits on Kojic Acid

Kojic acid, widely used in skincare for its brightening effects, will now be restricted to a maximum concentration of 1% in cosmetic products. This new limit takes effect for newly launched products on June 20, 2025, with full compliance required for all existing products by November 1, 2025.

Manufacturers and responsible brands must ensure their products meet these new safety standards to avoid potential penalties. These regulatory updates reflect the UK’s commitment to protecting consumers and keeping up with the latest scientific research in cosmetic safety.
