Support against Coronavirus: WESSLING Group tests the effectiveness of disinfectants

In the pandemic context due to COVID-19 hydroalcoholic products have become a rare commodity. Nevertheless, these skin aseptic solutions with bactericidal, fungicidal and especially virucidal properties are necessary to limit the spread of the COVID-19 virus. Many cosmetic companies have taken the initiative to produce hydroalcoholic solutions to supply health professionals and all institutions and companies that continue to be active in the daily life of the country to counteract with the current shortage. 

The joint order of the MS / MMP / ANSVSA no. 10/368/11 of 2010 regulates the approval mode for the introduction on the Romanian market of biocidal products, with subsequent modifications and completions. In addition to the endorsement file, efficacy reports made in 2 separate laboratories are also required to demonstrate the biocidal efficacy depending on the product type.

Composition and effectiveness of hydroalcoholic products

According to World Health Organization recommendations, hydroalcohol products must be at least composed of ethanol, hydrogen peroxide (or hydrogen peroxide), glycerol and distilled water to be effective.

The ethanol (alcohol) in the solution plays the major role as it has disinfectant and antiseptic properties. Its concentration in hydroalcoholic gels or solutions is the only one subject to regulations and must be controlled. In fact, is recomended the use of hydroalcoholic solutions or gels with an optimal alcohol concentration between 60% and 70% (volume/volume) or at a concentration between 520 and 630 mg/g.

Glycerol acts as a humectant and thus protects the skin to which the gel or hydroalcoholic solution is applied. 

Hydrogen peroxide is used to inactivate bacterial spores potentially present in the product but does not act as an antiseptic. 

How do we know that these disinfectant products are really effective? What is the guarantee?

To ensure the effectiveness of these products, companies producing hydroalcoholic products must therefore control the concentration of ethanol in the finished products. 

The WESSLING Group supports disinfectant manufacturers by exchanging information and expertise of the international network of specialists and we measure the concentration of ethanol and the natural bactericidal and fungicidal effects of chemical disinfectants and antiseptics.

The WESSLING laboratorys are ready to take the test requests for disinfectants.

Thus, we provide support to disinfectant companies and contribute to improving the current health situation.
