Antibacterial cleaning products used in the home fall into two general categories: personal cleansing and household cleaning. Antibacterial personal cleansing products and antibacterial household cleaning products differ significantly in their properties and ingredients, and in how they are used and regulated. Here is some information about these products.
Personal hygiene and regular housecleaning are essential to good health. Frequent handwashing is key to preventing the spread of microorganisms (also known as microbes or germs) that cause many common illnesses. And regular cleaning of surfaces in the home removes dirt and food particles on which germs can grow.
Personal cleansing and household cleaning products that contain an active antibacterial or antimicrobial ingredient provide extra protection against germs, including those that may cause disease. That's because their active ingredient helps them go beyond simple cleaning to kill or control the growth of microorganisms. (The words antibacterial and antimicrobial are often used interchangeably. Strictly speaking, however, antimicrobial means activity against a wide variety of microorganisms, while antibacterial refers to activity against bacteria.) Together with good cleaning habits and practices, these products play an important role in helping to prevent germs from spreading.
Why Is It Important to Kill Germs?
- Germs are most often spread by hands through person-to-person contact.
- Germs can enter our bodies through the mouth, nose, eyes and breaks in the skin without our even knowing we've been infected.
- Poor personal hygiene by foodhandlers is the second leading cause of foodborne illness.
- Americans spend about $5 billion each year on their colds - about $3 billion on doctors' visits and $2 billion on treatments.
- An estimated 60 million days of school and 50 million days of work are lost annually because of the common cold.
- Some 5.5 million visits to doctors' offices each year are due to skin infections.
- Germs can be transferred from inanimate surfaces to hands and vice-versa.
- Some germs can live on dry surfaces (such as toys) for several hours and moist surfaces (like bathroom sinks) for up to three days.
- Salmonella can survive freezing and can survive on dry surfaces for at least 24 hours.
- The average kitchen dishcloth can contain 4 billion living germs.
Antibacterial Personal Cleansing Products
Personal cleansing products intended to kill or inhibit certain bacteria on the hands or body are generally called antibacterial soaps or washes. Depending on their active ingredient(s) and specific formulation, these products are effective against the bacteria that can cause odor, skin infections, food poisoning, intestinal illnesses and other commonly transmitted diseases. First introduced in the 1920s to control odor-causing bacteria, antibacterial soaps are regulated by the U.S. Food and Drug Administration.
Benefits of Disinfecting Household Surfaces
- Regular cleaning products do a good job of removing soil, but only disinfectants or disinfectant cleaners (also known as antibacterial cleaners) kill the germs that can cause many illnesses.
- Surfaces like kitchen and bathroom counters, door knobs, toilet seats and children's toys may be contaminated with bacteria even when they're not visibly soiled.
- Germs can be spread to other surfaces on dirty cleaning cloths and sponges.
- Products that claim to kill germs must meet efficacy requirements and guidelines established by the U.S. Environmental Protection Agency (EPA), and must be registered with EPA and carry an EPA registration number on their label.
- In order for surfaces to be effectively disinfected, the instructions on product labels need to be followed carefully.

Q. What microorganisms do disinfectants or antibacterial cleaners kill on household surfaces?
A. Depending on the active ingredient(s) and the product formulation, they kill bacteria such as Salmonella and E. coli, which cause intestinal illness, and Staphylococcus which causes skin infections; fungus that causes athlete's foot; and viruses such as Herpes simplex, Rhinovirus, which is the leading cause of the common cold; and Rotavirus, the major cause of diarrhea in young children. Read the label to find out specifically which germs the product is intended to kill.
Q. How can I tell if a household cleaning product kills germs?
A. Look for the words "disinfect," "disinfectant," "antibacterial" or "sanitize" on the label, as well as an EPA registration number, as this ensures that the product has met EPA requirements for killing germs.
Antibacterial Household Cleaning Products
Household cleaning products intended to kill germs on inanimate surfaces are typically said on their labels to disinfect, kill bacteria or sanitize. Depending on their active ingredient(s) and specific formulation, these products may kill a wide variety of microorganisms that can live on household surfaces, such as foodborne bacteria like Salmonella; the cold virus; and fungus that causes athlete's foot. Household cleaning products designed to kill germs on surfaces have been available for more than 100 years. They are regulated by the U.S. Environmental Protection Agency.
