Facts You Need To Know When Buying Liquid Chlorine Bleach

by | Nov 15, 2022 | Health | 0 comments

Liquid chlorine bleach has been used to clean all kinds of surfaces, keep drinking water free of germs, and keep swimming pools clean. It can whiten laundry, paper, soap, straw, and cotton, among other things. Bleach is essential to public health because it is one of the most common and cheap ways to clean. 

Using bleach solutions on surfaces people often touch, like door knobs, and on surfaces that come in contact with food can help stop the spread of diseases by killing pathogens. Bleach is often used to clean surfaces with a high risk of spreading infectious diseases and antibiotic-resistant superbugs. This includes child care centres, adult care centres, and hospitals. During an emergency or after a natural disaster, liquid chlorine bleach can clean contaminated water sources and stop mould from growing.

A More In-Depth Look at Chlorine Bleach

Most people have liquid chlorine bleach, a type of household bleach. Household bleach is sold in supermarkets and other stores as a 6% sodium hypochlorite and water solution. Sodium hypochlorite is made by mixing chlorine gas with a resolution of sodium hydroxide (NaOH). The compound of sodium hypochlorite breaks down over time into salt and water. So, older bottles of chlorine bleach might not have the same 6% concentration of sodium hypochlorite that they did when they were bought.

Calcium hypochlorite is another bleaching compound, often called bleaching powder or granular bleach. It is a dry solid sold in the form of granules or disks. 

How Does Chlorine Bleach Disinfect?

When liquid chlorine bleach is mixed with water, a weak acid called hypochlorous acid is made. This acid is what gives chlorine bleach its strong ability to kill germs. Hypochlorous acid is not charged, so it can quickly get in touch with and pass through the cell walls or membranes of bacteria or the shells (capsids) of viruses or norovirus pathogens. Once inside the pathogen, the hypochlorous acid reacts chemically with the proteins, which causes their complex structure to unravel. This stops the proteins from doing their jobs and kills the pathogen.

For bleach to kill a pathogen, it needs to be in contact with it long enough time. The recommended contact time is based on the pathogen, the temperature, and the strength of the bleach solution. Some pathogens need longer times of contact than others. 

Is Bleach Harmful To The Environment?

When liquid chlorine bleach is used according to the directions on the label, it does not hurt the environment. As germs and other organic matter react with chlorine bleach, it breaks down into primarily salty water. Any bleach that has not responded will break down when it meets organic matter in the wastewater collection system or when the city treats its wastewater.

Using liquid chlorine bleach in ways, it is not meant to be used is terrible for the environment. Because of this, it is always best to follow the instructions on the bleach label.
