Distinguishing pearlescent pigments from titanium dioxide 

The Titanium Dioxide Manufacturers Association (TDMA) notes recent media coverage referring to the presence of titanium dioxide (TiO2) nanoparticles in certain cosmetic products. 

TDMA wishes to clarify the distinction between pigmentary TiO₂, nano TiO₂ and pearlescent pigments, based on existing EU scientific assessments. 

Pearlescent pigments are distinct from pigmentary TiO₂.  

Pearlescent pigments used in cosmetics are composite materials, typically based on substrates such as potassium aluminium silicate (mica), onto which small amounts of TiO2 may be applied to create optical effects. In these materials, TiO2 is only a minor constituent and is bound within a composite structure. They are manufactured differently and are not equivalent to pigmentary TiO2 or TiO2 nanoforms. 

 The SCCS Opinion on TiO₂ does not apply to pearlescent pigments. 

The EU Scientific Committee on Consumer Safety (SCCS), in its Opinion of 6 October 2020, assessed pigmentary TiO2 in cosmetic products that may give rise to consumer exposure via inhalation (e.g. sprays, powders). The SCCS explicitly states that its conclusions are not applicable to pearlescent pigments because of their composite nature, of which TiO2 is only a minor constituent. 

 The TDMA supports clear, science-based communication and believes it is important to distinguish between different materials, manufacturing processes, and regulatory assessments to avoid confusion and ensure accurate public understanding..
