Commonly touched surfaces are efficiently spreading harmful microbes. This statement is founded on two different facts: long lifetime of microbes and accumulation of microbes on surfaces. Lifetime of microbes on various surfaces is typically counted in days. Microbes tend to land on such surfaces upon release e.g. as aerosols and droplets. However, upon landing on surfaces the concentration is increased with several millions times. Upon touching such surfaces there’s an inherent risk that microbes located earlier on the surface will be transferred to mouth, nose or eye by hands and especially fingers.

​

Infection risk described earlier can be mitigated by applying such materials and chemicals, which either destroy or surround harmful microbes. The solution can as simple as soap; it has multiple features, which can supply protection against microbes. Regarding Covid, soap attacks the lipid envelope and which leads to destruction of the virus. Regarding non-enveloped viruses and bacteria soap reduces the infection risk via another mechanism: upon being covered by soap molecules, these harmful microbes are easily washed away e.g. from hands.

Clean Kill hygiene products contain two different active agents against harmful microbes: soap and metal ions. The incorporated metal ion has been shown to act efficiently against bacteria and viruses. Release rate of these is steady and long lasting due to wearing of the composition and relative high materials thickness. Naturally, the incorporated active agents are fully harmless for people and animals.
