polymers for long lasting disinfection

who prolongs the life of instant disinfectants? we do.

The ongoing Covid-19 pandemic has brought to the forefront, the need to disinfect the surfaces around us. As a result, consumer awareness for cleaning and disinfection has increased significantly, resulting in unprecedented increase in sales of cleaning and disinfecting products.

worldwide surface disinfection market
The worldwide retail sales of disinfectants and multipurpose cleaners increased 9% in 2020 vs prior year after witnessing years of declining growth1. This $6.2B worldwide market is expected to continue its fast growth rate in future, due to changing consumer habits.

Why long-lasting disinfection?
Current disinfecting products are effective at instant disinfection, however, with repeated exposure and human contact, the surfaces are re-contaminated and require frequent reapplication of the disinfectant.

how it works

Ashland presents innovation addressing the above challenge, targeting long-lasting disinfection, for as long as 24 hours. Sprayable polymers with the ability to form substantive films significantly extend the effect of common biocides. Our tests using EPA RSS protocol 01-1A2 demonstrate long lasting disinfection enabled by polymers in combination with quaternary ammonium compounds, which are the most common disinfecting agent used worldwide in household applications.

This also reduces the need for repeated application, thereby improving the sustainability profile and cost efficiency of the product. This technology also helps improve the efficacy of existing disinfectant formulations significantly by addition of commercially available polymeric film formers. This can allow brand owners to offer a significantly improved product with new consumer benefits of long-lasting efficacy with high speed to market.
