UK seeks data on safety of cosmetic ingredients

A UK regulator has issued two calls to submit scientific information relevant to the safety assessment of cosmetic ingredients.

In the first, the Office for Product Safety and Standards (OPSS) will evaluate the safety of the following ingredients in cosmetic products due to their suspected endocrine disrupting properties:

  • Triclosan
  • Triclocarban
  • 4-Methylbenzylidene camphor
  • Salicylic acid
  • Butylparaben
  • Methylparaben

“If ingredients will be used in products that may foreseeably be used by children or pregnant women, relevant data to support the safety and exposure estimates should be provided for these populations,” said OPSS.

The deadline for submission is 15 December 2023.

The second call relates to the safety assessment of the following nanomaterials used in cosmetics:

  • Platinum
  • Copper
  • Silver
  • Gold, colloidal gold, gold thioethylamino hyaluronic acid
  • Silica, hydrated silica, silica silylate, silica dimethyl silylate
  • Lithium magnesium sodium silicate
  • Hydroxyapatite

The deadline for submission for silica, hydrated silica, silica silylate, and silica dimethyl silylate is 27 June 2025. For all other substances, the deadline is 22 December 2023.

The Scientific Advisory Group on Chemical Safety (SAG-CS) will use 70kg as the default bodyweight assumption for adults for both safety assessments.
