Silvet Advanced Otic is an antibacterial/antifungal neutral deep cleansing formulation utilizing 30ppm Nano-particles of Silver, purified water and 2% Boric Acid. This odorless, astringent, general broad-spectrum cleanser can be used daily or on an as needed basis. The complex Boric Acid formula dries the ear by pulling moisture out without the use of harsh chemicals, such as alcohol or propylene glycol, which can cause ototoxicity and possibly lead to deafness or damage to the ear.
