SCCS Opinion on Biphenyl-2-ol and Sodium 2-biphenylolate as preservatives in cosmetics
Ingredients: BIPHENYL-2-OL; SODIUM 2-BIPHENYLOLATE

Date of publication: 25/10/2024

On October 25, 2024, the Scientific Commitee on Consumer Safety (SCCS) published its opinion on the safety of Biphenyl-2-ol and Sodium 2-biphenylolate as preservatives in cosmetics.

What’s new?

On October 25, 2024, the SCCS published its opinion on the use of Biphenyl-2-ol (o-Phenylphenol) and Sodium 2-biphenylolate (Sodium o-Phenylphenate) as preservatives in cosmetic products. Biphenyl-2-ol is currently restricted in Annex V (entry nº7) of the Cosmetics Regulation 1223/2009 with a maximum concentration of 0.2% (as phenol) in rinse-off products and 0.15% (as phenol) in leave-on products.

Based on the data provided, the SCCS considers o-Phenylphenol to be safe as a preservative at the current concentrations as described in the Cosmetics Regulation. The SCCS also considers Sodium o-Phenylphenate safe as a preservative ate the same concentrations. When used together, the maximum combined concentration should be:

  • 0.15% in leave-on products.
  • 0.2% in rinse-off products.

The assessment did not address the environmental safety of o-Phenylphenol and Sodium o-Phenylphenate and did not consider oral and inhalation routes.
