Bleach is the most commonly used disinfectant for surfaces contaminated with infectious diseases and is recommended by the World Health Organization. Other disinfectants like quats, alcohol, and hydrogen peroxide are also used for decontamination.

The problem? Healthcare workers and patients are being infected at high rates due to ineffective decontamination. During the Ebola crisis, 1 out of every 20 people who died was a healthcare worker, and in the US, 1 out of every 25 patients will contract a hospital-acquired infection, leading to 75,000 deaths and $28 billion lost in the healthcare system each year. 

Currently used disinfectants are transparent, making it easy to miss spots. They form droplets and run off when applied to waterproof surfaces, leaving gaps in coverage. Disinfectants also require a certain amount of contact time to kill pathogens (e.g. 3-4 minutes to kill C. difficile), but it's difficult to enforce compliance with waiting long enough. All of these problems mean that even if a disinfectant is used, a surface could still be contaminated.


Note: Bleach droplets emphasized to show poor coverage. Normally transparent and difficult to visualize.

Our solution is Highlight®, a patent-pending, powdered additive for disinfectant solutions that enhances the process of infectious disease decontamination by eliminating human error and increasing compliance. Highlight® is directly mixed into disinfectants at point-of-use and works by colorizing the disinfectant and modifying the liquid properties to:

  • visualize sprayed regions
  • ensure full coverage and adherence to surfaces
  • increase viscosity and prevent misting of harmful fumes

Highlight® fades to clear over time to provide real-time visual feedback of when decontamination is complete and to prevent staining.
