About 95 percent to 98 percent of household bleach, made with sodium hypochlorite, quickly breaks down into salt and water upon use. The remaining 2 percent to 5 percent breaks down further and is effectively treated by municipal wastewater treatment plants or septic systems.
If clean has a smell, it's the iconic scent of bleach. Its barely detectable aroma announces the towel is ready to use. Its lingering scent on a white robe offers assurance you can wrap yourself in.
With so much power in one bottle of bleach, some worry about its environmental impact. But the simple fact is: Bleach starts as salt and water and ends as salt and water. Household bleach contains no free chlorine, and it essentially breaks down into salt and water during or quickly after use. In November 2009, Clorox announced that we will begin transitioning our U.S. bleach manufacturing operations from using chlorine to high-strength bleach as a raw material. High-strength bleach is a water-based solution of concentrated sodium hypochlorite that we dilute down to specific levels for household and industry use. This decision was driven by our commitment to strengthen our operations and add another layer of security to our operations.

The bleach cycle – from production to household use to disposal down the drain – is simple. It begins and ends with sodium chloride, common table salt. We call it the salt-to-salt cycle.
Since it was introduced in 1913, Clorox® regular bleach has had a long history of use in places where killing germs is critical: in hospitals, nursing homes, child-care centers, schools and restaurants. During World War I, in the days before penicillin, the lives of wounded soldiers were saved by the antibacterial properties of bleach. In the 1960s, when the first Apollo flights were heading into space, NASA used Clorox® brand bleach to decontaminate the capsules returning from orbit.
Confidence in the efficacy and impact of disinfecting bleach is why the world's leading public health agencies -- the World Health Organization and the Centers for Disease Control and Prevention -- recommend the use of bleach for controlling the spread of pathogens that can cause infections and other health threats.
Bleach is one of the most widely available, affordable disinfectants on earth, and the role it plays in public health continues to be critical.
Frogs around the world are disappearing at an alarming rate.
One of the culprits detrimental to frogs is a chytrid (KIT-rid) fungus. To combat it, zoos and aquariums around the world are taking the most threatened species into "protective custody" in bio-secure environments. The frogs are treated with an anti-fungal medicine. Everything else is treated with a bleach solution to prevent the spread of the fungus: boots, clothing, instruments, and even the frogs' new environments.
