Explore how AEGIS VES 240® can kill microbial pathogens and thus reduce cross-contamination on treated surfaces.



AEGIS VES 240® helps remove unwanted germs from surfaces, and the active ingredient is free from bleach, dyes, and phosphates. It has a long and safe history of use against a broad spectrum of viruses, bacteria, and fungi.

How does AEGIS VES 240® Work?

Microbes are abundant in the environment where they attach to surfaces and absorb available nutrients to support their survival and growth. While they can survive under a variety of conditions, they thrive in warm, humid, moisture-rich environments. Soils and other organic matter present on or within building materials, furnishings, and other objects provide microorganisms a rich source of nutrients.

Cleaning is the removal of germs, soil, dirt, debris, salts, oils, blood from objects or surfaces. While cleaning is important, germs are not killed. AEGIS VES 240® disinfection protection is applied to inanimate surfaces or objects to kill and inactivate contaminating microbes. When regular topical surface cleanings are not enough, disinfectant use is critical for destroying viruses, bacteria, and fungi.

The mechanisms of the disinfecting action of AEGIS VES 240®

Quaternary ammonium salts (QAS) are also commonly called “Quats.” Multi-Quat Disinfectant, like AEGIS VES 240®, contains a combination of different QAS as the active component. QAS are cationic molecules that possess antimicrobial activity against a wide range of microbes, including Gram-Positive and Gram-Negative bacteria, fungi, and some viruses.

In its most basic form, quaternary ammonium is a permanently charged cation with a central nitrogen atom surrounded by four R-groups, most commonly alkyl or aryl groups. Chemically, QAS are organically substituted ammonium compounds in which the nitrogen atom has a valence of 5, four of the substituent radicals (R1-R4) are alkyl or heterocyclic radicals of a given size or chain length, and the fifth (X-) is a halide, sulfate, or similar radical. Each compound exhibits its own antimicrobial characteristics. Some quaternary ammonium compounds remain active in hard water and are tolerant of anionic residues. The activity and efficacy of a QAS is dependent on the length of the alkyl chain, the presence of a perfluorinated group, and the number of cationic ammonium groups.

The antimicrobial activity of QAS is primarily attributed to the disruption of the microbial cell membrane. Specifically, the positively charged QAS interact with the negatively charged cell membrane and membrane-bound proteins of the microbial cell. This interaction disrupts the membrane function, causing eventual lysing of the cell membrane and subsequent leakage of cytoplasmic materials. Additional modes of action by QAS include inactivation of energy-producing enzymes and denaturation of essential cell proteins. In some instances, QAS may interact with bacterial DNA, thus inhibiting cellular replication.

How Do You Apply AEGIS VES 240® to a Surface?

Simply put, clean and dry the targeted surface. AEGIS VES 240® will need to be diluted as per the product label. The technology can be sprayed and wiped dry with a cloth, sponge, or mop or it can air dry. Drying time will vary from surface substrate to substrate.

What PPE Should You Wear?

When applying AEGIS Microbe Shield to surfaces, application professionals should always use the following recommended Personal Protective Equipment (PPE):

  • Wear protective eyewear (goggles, face shield, or safety glasses)
  • Gloves (rubber or chemical-resistant)
  • Protective clothing - Long sleeves and pants
