Chlorine Bleach vs. Oxygen Bleach

What's the Difference?

Chlorine bleach and oxygen bleach are both commonly used for laundry and household cleaning purposes, but they have distinct differences. Chlorine bleach, also known as sodium hypochlorite, is a strong and effective disinfectant that can remove tough stains and kill bacteria and viruses. However, it has a strong and pungent odor and can cause skin and respiratory irritations. On the other hand, oxygen bleach, also called sodium percarbonate, is a gentler alternative that uses hydrogen peroxide to break down stains and brighten fabrics. It is color-safe and environmentally friendly, as it breaks down into water and oxygen. While oxygen bleach may not be as powerful as chlorine bleach, it is a safer option for those with sensitivities or concerns about harsh chemicals.

Further Detail


When it comes to household cleaning, bleach is a popular choice due to its powerful disinfecting and stain-removing properties. However, there are different types of bleach available, each with its own set of attributes and uses. In this article, we will compare two commonly used bleaches: chlorine bleach and oxygen bleach. By understanding their differences, you can make an informed decision on which bleach is best suited for your specific cleaning needs.

Chlorine Bleach

Chlorine bleach, also known as sodium hypochlorite, is a strong and effective disinfectant. It is widely used for sanitizing surfaces, killing bacteria, viruses, and fungi. One of the key attributes of chlorine bleach is its ability to remove tough stains, such as those caused by coffee, tea, or red wine. It is particularly effective on white fabrics, as it can brighten and whiten them.

However, chlorine bleach has some drawbacks. It has a strong and distinct odor that can be overpowering, and it can irritate the skin and eyes if not used with caution. Additionally, chlorine bleach is not suitable for all materials, as it can damage or fade certain fabrics and surfaces. It is important to carefully read the instructions and follow the recommended dilution ratios when using chlorine bleach.

Oxygen Bleach

Oxygen bleach, also known as sodium percarbonate, is a gentler alternative to chlorine bleach. It is a non-toxic and environmentally friendly bleach option, making it a popular choice for those who prefer eco-friendly cleaning products. Oxygen bleach works by releasing oxygen when mixed with water, which helps to break down stains and dirt.

One of the main advantages of oxygen bleach is its versatility. It can be used on a wide range of materials, including colored fabrics, carpets, and even delicate surfaces like wood. Unlike chlorine bleach, oxygen bleach does not cause discoloration or damage to most materials. It is also safe to use around children and pets, as it does not emit harmful fumes.

However, oxygen bleach may not be as effective as chlorine bleach when it comes to removing tough stains or disinfecting surfaces. It may require longer soaking or scrubbing to achieve the desired results. Additionally, oxygen bleach is not suitable for use on certain types of stains, such as rust or ink stains.

Key Differences

While both chlorine bleach and oxygen bleach have their own unique attributes, there are some key differences between the two:

  • Disinfecting Power: Chlorine bleach is a more potent disinfectant compared to oxygen bleach. It can effectively kill a wide range of bacteria, viruses, and fungi, making it ideal for sanitizing surfaces.
  • Stain Removal: Chlorine bleach is known for its exceptional stain-removing capabilities, especially on white fabrics. Oxygen bleach, although effective, may require more time and effort to remove tough stains.
  • Safety: Oxygen bleach is considered safer to use compared to chlorine bleach. It does not emit strong fumes, making it more pleasant to work with. It is also less likely to cause skin or eye irritation.
  • Material Compatibility: Chlorine bleach can damage or fade certain fabrics and surfaces, while oxygen bleach is generally safe to use on a wide range of materials, including colored fabrics and delicate surfaces.
  • Environmental Impact: Oxygen bleach is considered more environmentally friendly as it breaks down into water, oxygen, and soda ash, leaving no harmful residues behind. Chlorine bleach, on the other hand, can release toxic compounds into the environment.


Choosing between chlorine bleach and oxygen bleach depends on your specific cleaning needs and preferences. If you require a powerful disinfectant and stain remover, chlorine bleach may be the better option. However, if you prioritize safety, environmental friendliness, and versatility, oxygen bleach is a great alternative. It is always important to carefully read and follow the instructions on the bleach packaging to ensure safe and effective use.
