According to the SCCS opinion, a purity of [greater than or equal to] 99% in rutile form and a photocatalytic activity of less than 10% in nano form (compared to the corresponding non-coated or non-doped references) are among the main requirements that confirm the product's stability and safety.
In case low concentration of rutile phase (10-20%) is added to anatase phase, photocatalytic properties of titania increase.
