Conclusion of the opinion:

(1) In light of the data provided, does the SCCS consider HAA299 (nano) safe when used as a UV-filter in cosmetic products up to a maximum concentration of 10%?

The available data indicate that HAA299 (nano) is a practically insoluble material, with very low dermal and oral absorption. Due to the very low systemic availability, the material is unlikely to exert systemic genotoxic or reproductive effects. The NOAEL of 1000 mg/kg/day indicates that the material is of overall low toxicological concern. Given the low dermal penetration, and low systemic toxicity, the calculation of margin of safety (MoS) is not appropriate in this case. The SCCS considers that HAA299 (nano) as covered within the provided characteristics (minimum purity equal to or above 97%, median particle size in terms of particle number equal to or above 50 nm) is safe when used as a UV-filter in dermally-applied cosmetic products up to a maximum concentration of 10%.

Based on the inflammatory effects on the lung after the acute inhalation exposure, the SCCS has concerns regarding the repeated use of products containing HAA299 (nano) in applications that could lead to inhalation exposure. Therefore, the SCCS does not recommend the use of HAA299 (nano) in applications that could lead to exposure of the consumer’s lungs via inhalation.

(2) In view of the previous SCCS opinion (SCCS/1533/14) does the SCCS consider HAA299 non-nano and nano form safe when used as a UV-filter in cosmetic products up to a maximum concentration of 10%?

The data considered in this Opinion has not provided any new or additional concern that merits a revision of the previous SCCS opinion (SCCS/1533/14). Therefore, the SCCS considers HAA299, either as non-nano or nano form, safe when used as a UV-filter in dermally-applied cosmetic products up to a maximum concentration of 10%. The SCCS considers that the combined maximum concentration of non-nano and nano forms of HAA299 should not exceed 10% in a cosmetic product.

(3) In case the SCCS finds HAA299 (nano) not safe, does it still uphold the conclusions of the SCCS/1533/14 opinion with regard to the safe use of HAA299 non-nano form?

/

(4) Does the SCCS have any further scientific concerns (on human health) with regard to the use of HAA299 (nano) in cosmetic products?

This opinion is based on the currently available scientific evidence, which shows an overall very low or lack of dermal absorption of HAA299 (nano) in human skin. If any new evidence emerges in the future to show that HAA299 (nano) used as UV-filter in cosmetic products can penetrate human skin (healthy, compromised, sunburnt or damaged skin) to reach viable cells in higher levels than demonstrated in this submission, then the SCCS may consider revising this assessment.
