As per the provision of the Ministry of Health:

All products that boast a disinfection action on the label are classifiable as biocidal products – and are placed on the market only after obtaining a specific marketing authorization from the Ministry of Health or the European Commission. Products bearing the term „sanitizing/sanitizing“ on the label are also considered to fall under the definition of biocidal products and are therefore subject to the relevant authorization regime.

Sanitizing products sold in Italy must have the following label on the label: „sterilization products authorized by the Ministry of Health or authorized by the European Union. /…/ . AUT (in accordance with EU Regulation No. 528/2012)“ or: „Operating Room Registration of Internal Medicine of the Ministry of Health…“
The registration number or authorization number issued by the Ministry of Health or the European Commission ensures that the biocidal product is checked before being placed on the market to assess its safety for consumers and the environment and its efficacy according to the authorized instructions and conditions of use.
