At what concentration in the finished product must the warning “Contains formaldehyde” appear on the label of a cosmetic? The regulation currently sets it at 0.05%, but this threshold could be reviewed: the European Commission has just asked the SCCS to re-evaluate it. The Scientific Committee accepted this mandate by written procedure on 12 February 2021.

However, the discussions in the Working Group on Cosmetic Products concluded that suitable alternative substances were available and hence a derogation request under Art. 15(2) was rejected.
