How Is Bleach Made? Our Most Detailed Explanation

Bleach is one of the most underappreciated components of a cleaning kit. It is relatively inexpensive but quite effective as a disinfectant. It is readily available and pretty straightforward to use as well. When something has so many great qualities, it is only natural to ask the question, how is bleach made? Let us answer that question today.

Types of bleach

Before we delve into the details of bleach, it is important to understand that there are different types of bleaches out there. We will talk about the most commonly available bleach. Keep in mind that there has been an influx of eco-friendly bleaches of late. The composition of these bleaches can vary a lot and they usually contain some form of organic ingredient such as lemon juice, tea tree oil, thyme oil, etc. Read our article on “how to disinfect without bleach” to find more about bleaches you can make yourself. Today we will look at the most common type of bleach – industrial or chemical bleach.

So, what is bleach made up of?

Bleach works its wonders by releasing chlorine onto the surface which results in what is called disinfecting. Bleach is made up of a solution of Sodium hypochlorite. The stuff is widely manufactured which explains its affordability.

The raw components of bleach are chlorine gas, caustic soda, and water. The caustic soda solution is diluted to about 25% using water. The chlorine gas is then circulated through the caustic soda solution and this results in the formation of Sodium hypochlorite. Of course, there are finer elements to this entire process. This is just an overview.

The sodium hypochlorite thus obtained can contain different impurities and these are removed by employing a series of filters. It is also cooled to prevent any further reactions.

The sodium hypochlorite thus obtained is way too strong for use as bleach and is diluted to 5.25%. This is then poured into bottles and containers, sealed and shipped.

A reputed brand will use high-quality raw materials and will ensure that the manufacturing process is followed precisely. Finally, no corners will be cut when it comes to testing and quality control to ensure that the bleach you get is of a great standard.

There are other chemicals as well that have properties similar to that of sodium hypochlorite and can be technically used as bleach. However, these aren’t quite as suited to home use as sodium hypochlorite is.

It is also important to remember that contrary to popular belief, bleach won’t last forever. Always buy the most recently manufactured bleach that you can lay your hands on. It is also important to store bleach as per the manufacturer’s instructions. This is very important as it can mean all the difference between an effective disinfectant and a useless bottle of liquid. Finally, understand the risks associated with chemical bleach and never use it in a manner that can be harmful to you or those around you.

Also, a word of warning. Do not try to replicate the manufacturing process mentioned here at home. It releases a lot of heat as well as dangerous fumes.
