EU Restricts Two Substances Used in Nail Products

Press Release: December 05, 2020

On December 2, 2020, the European Commission’s new restriction on the use of HEMA and Di-HEMA TMHDC in cosmetics products came into effect. This means that on the following dates products containing these substances and not complying with the conditions in Regulation (EU) 2020/1682 must:


  • June 2, 2021 – not be placed onto the market in the EU
  • September 3, 2021 – not be made available on the market in the EU


Regulation (EU) 2020/1683 of November 12, 2020, amends Annex III of Regulation (EC) 1223/2009. This follows opinion of the Scientific Committee on Consumer Safety (SCCS), which found that both substances were not likely to pose a risk of sensitization when applied correctly to the nail plate in concentrations up to:

  • HEMA – 35%
  • Di-HEMA-TMHDC – 99%


The opinion also noted that both substances are weak to moderate sensitizers and pose a risk of sensitization when the product is misused – either through inappropriate application or unintentional contamination of the skin adjacent to the nails under normal and reasonably foreseeable conditions of use.


Products containing these substances are therefore only for professional use as they must be applied with a high level of precision. These products must therefore carry a message that states the following conditions of use and warning – For professional use only. Can cause an allergic reaction.


The chemical names for these substances are:

  • HEMA – 2-Hydroxyethyl Methacrylate
  • Di-HEMA-TMHDC – 11,14-Dioxa-2,9- diazaheptadec-16- enoic Acid, 4,4,6,16- tetramethyl-10,15- dioxo, 2-[(2-methyl- 1-oxo-2-propenyl) oxy]ethyl ester
