Our products’ sustainability is becoming an ever more important benchmark for the global leather market. We work with the Research and Development department to innovate and develop products and technologies capable of offering alternatives that make a consistent and significant contribution to social, environmental and economic well-being.


The Technology

Additive with
silver microparticles.

This is a nanotechnology intended to inactivate the SARS-Cov-2 virus, which causes Covid-19.

Silver microparticles are added to the leather’s coating during the production process. These microparticles are antiviral. The application does not prevent people from contracting the disease, but it does permanently protect the Leather’s surface and stops it from transporting viruses that could otherwise pose a health risk.

How it works


The microparticles are created by synthesizing silver salts, which were chosen for their well-known antiviral properties, which are then stabilized using nanotechnology. These microparticles interact, accumulate and penetrate into the protein forming the viral membrane (viruses are contained within a lipoprotein layer), affecting their permeability (ability to breathe). This affects the virus’s DNA, consequently rendering it inactive.


Leather that uses this technology is recommended for surfaces that are constantly exposed and therefore more susceptible to viral contact, including furniture, seating and steering wheels. Frequently handled items such as clothing, handbags and wallets can also be made using the same leather.

Results


During tests conducted at the level 3 biosecurity laboratory (NB3) at the University of São Paulo's Institute of Biomedical Sciences (ICP – USP), the material rendered 99% of SARS-CoV-2 viruses inactive within 30 minutes of coming into contact with the viral particles.


The tests complied with the international ISO 21,702 standard, which describes the most effective methods of detecting antiviral activity in plastics and non-porous surfaces.

FAQ

No, the material used in the leather, for the inhibition of viruses and bacteria, does not affect other animals and does not present risks, including to people.

During tests conducted at the level 3 biosecurity laboratory (NB3) at the University of São Paulo's Institute of Biomedical Sciences (ICP – USP), the material rendered 99% of SARS-CoV-2 viruses inactive within 30 minutes of coming into contact with the viral particles.

The silver microparticles are able to inactivate the virus by two mechanisms: in its membrane - where they break this external coating of the virus, inactivate its entry into the host cells, and oxidize the genetic material of the exposed virus, completely inactivating its ability to multiply.

Leather that uses this technology is recommended for surfaces that are constantly exposed and therefore more susceptible to viral contact, including furniture, seating and steering wheels. Frequently handled items such as clothing, handbags and wallets can also be made using the same leather.

Silver is an inorganic active, so it is characterized by high chemical resistance and stability. In addition, it stays intact in the washing process, which is why its applications offer protection that takes into account the useful life of the applied material. However, this longevity also depends on good use and the use of adequate cleaning and maintenance products.
