On November 9, 2020, the European Commission (EC) Scientific Committee on Consumer Safety (SCCS) published two draft opinions for public comment.  In the preliminary opinion on hydroxyapatite (nano), SCCS considered whether the nanomaterial hydroxyapatite is safe when used in leave-on and rinse-off dermal and oral cosmetic products according to the reported maximum concentrations and specifications, taking into account reasonably foreseeable exposure conditions.  SCCS states that having considered the data provided, as well as other relevant information available in the scientific literature, it cannot conclude whether hydroxyapatite composed of rod-shaped nanoparticles for use in oral-care cosmetic products at the maximum concentrations and specifications is safe.  According to SCCS, this is because the available data and information are insufficient to exclude concerns over the genotoxic potential of hydroxyapatite (nano).  The EC also asked if SCCS has any further scientific concerns with regard to the use of hydroxyapatite in nano form in cosmetic products.  SCCS responded that although its preliminary opinion considers rod-shaped hydroxyapatite nanoparticles, it is aware that needle-shaped hydroxyapatite nanoparticles may also be produced.  SCCS states that the available information indicates that hydroxyapatite nanoparticles in needle-shaped form are of concern in relation to potential toxicity and should not be used in cosmetic products.
