SCCS Issued a Preliminary Opinion on Water-soluble Zinc Salts Used in Oral Hygiene Products

On July 4, 2023, the European Union Scientific Committee on Consumer Safety (SCCS) pulished the preliminary opinion on water-soluble zinc salts (SCCS/1657/23). The deadline for comments was set for 8 September 2023.

The SCCS has calculated aggregate exposure to water-soluble zinc salts via toothpaste at the concentrations of 1% and from diet and concluded that the use of zinc in toothpaste is safe per se except for children under the age of 1 year because the intake exceeds the upper limit level. For children up to 1 year of age, the SCCS recommends a safe concentration of 0.72% for soluble zinc salts (as zinc) in toothpaste. The inclusion of zinc in mouthwash at 0.1% Zn is considered safe across all age groups.
