Livinguard technologies are based on the ability of polycationic surfaces to deactivate microorganisms such as bacteria, viruses, and certain types of fungus, which does not decrease even with repeated washing.
This principle has been described across scientific literature for a good 20 years. So far, however, its understanding and practical application have been limited. Livinguard has now made use of it to develop and patent an approach that represents a paradigm shift compared to conventional approaches:
- Various methods of binding a range of cationic compounds to textiles and other surfaces.
- A portfolio of optimized chemical processes for inactivating bacteria and viruses without the use of conventional metallic-based antimicrobials such as silver, copper, zinc, etc.
- A process to combine these with other properties such as water repellency, hydrophilicity, etc.
According to the scientific literature, the mechanism for virus inactivation is likely to be based on the destruction of the protein capsule by adsorbing negatively charged proteins onto the positively charged surface, ultimately leading to the release of non-infectious RNA.
Studies have shown that the treated material (especially the textiles tested so far) retains its properties even after repeated rinsing or washing. The fact that the antimicrobial effect does not wash off is the main reason for its long-term durability and good skin tolerance.
