Ever wondered what exactly is in bleach? Let’s check it out.

Chemical Composition of Bleach

Bleach is most commonly used to disinfect, remove stains and whiten clothes. When you look beyond its purpose and look at the chemical components of bleach, you’ll see that chlorine is actually the basis. Chlorine bleach usually contains calcium hypochlorite, whereas oxygen bleach contains hydrogen peroxide.

How Does Bleach Work?

When you’re using bleach to whiten your clothes or disinfect an area of your home, chances are you don’t often think about what is happening from a chemical perspective. So what’s actually going on when you use bleach?

Oxidizing Bleach

When applied onto a surface, oxidizing bleach breaks the chemical bonds of the part of the molecule that has color – this is also known as the chromophore. As a result of this chemical reaction, the molecule does one of two things: it begins to reflect a color that’s outside the visible spectrum or it has no color.

Reducing Bleach

If you’re working with reducing bleach, the kind of chemical reaction that happens is slightly different. Chemically speaking, reducing bleach changes the double bonds into single bonds. As a result, the surface is colorless since the molecules optical properties have also been changed.

The History of Bleach

Now that you know a bit more about the chemical composition of bleach, let’s take a quick look at the history of bleach.
Rewind back to 5000 BC in Egypt. Egyptians knew a thing or two about bleaching, as they would purposely discolor linens by leaving them out in the sunlight for extended periods of time. Furthermore, they would mix wood ashes with water to create a substance called lye. Soaking linens in this substance would also lighten colors.

Fast forward to the 12th century AD in Holland, where the Dutch became very well known for their bleaching techniques. They actually added sour milk to lye to soften its effects!
This worked so well that all brown linens that were manufactured in Scotland were sent to Holland for bleaching, where they would soak and sun-dry the linen multiple times to whiten it – this could take up to 8 weeks!

• In the 16th century, 8 weeks was cut down considerably, as John Robuck began using diluted sulphuric acid in place of sour milk.
• In 1785, French scientist Claude Berthollet discovered that chlorine actually destroyed vegetable colors; he then introduced chlorine into the bleaching process.
• In 1799, Charles Tennant of Scotland discovered that when chloride lime was added to bleach, it produced the substance now known as bleaching powder.
