This test involves putting the product up against various microorganisms specified in ISO 14729 (Candida albicans, Fusarium solani, Serratia marcescens, Pseudomonas aeruginosa and Staphylococcus aureus) in order to prove the tested product’s disinfectant capacity.
Structurally speaking, the coronavirus belongs to the “membraned” group of viruses. This (lipid) envelope happens to be one of its weaknesses. Removing its membrane —which, being lipidic, can be destroyed simply using soap and water— deactivates the virus.
Specific studies have yet to be conducted on adenoviruses/coronaviruses, but what we do know is that hydrogen peroxide (which is present in the One-Step-t product’s disinfectant solution) is capable of eliminating pathogenic microorganisms through oxidation, a process that destroys their membranes.
Another advantage is that with the One-Step-t peroxide system, where (bubble-free) neutralisation occurs 12 minutes after adding the neutralising tablet, contact lenses remain in direct contact with the 3% peroxide solution at all times, further intensifying its disinfectant power.
