SCCS Number: SCCS/1665/24
Adopted on: 20 June 2024

Conclusion of the opinion:

(1) In light of the data provided and taking under consideration the classification as toxic for reproduction Cat. 2, does the SCCS consider micron-sized particulate Silver safe when used up to a maximum concentration of 0.2 % in rinse-off and 0.3 % in leave-on cosmetic products?

In light of the data provided and taking under consideration the classification as toxic for reproduction Cat. 2, the SCCS considers micron-sized particulate Silver not safe at concentrations up to 0.2 % in rinse-off and 0.3 % in leave-on cosmetic products when used alone or in combination.

However, the use of micron-sized particulate Silver in eye shadow and oral exposure products (lip balm, toothpaste and mouthwash) at concentrations mentioned in Section 3.5 is considered safe, either used alone or in combination.

(2) Alternatively, what is according to the SCCS, the maximum concentration considered safe for use of micron-sized particulate Silver in cosmetic products?

/

(3) Does the SCCS have any further scientific concerns with regard to the use of micron-sized particulate Silver in cosmetic products
