Active Ingredient in Dial Antibacterial Soap

Beauty and Fashion

Dial is a well-known brand that offers a wide range of personal care products, including antibacterial soap. Many people rely on Dial soap to effectively kill germs and keep their hands clean and protected. But have you ever wondered what the active ingredient in Dial antibacterial soap is? In this article, we will explore the main active ingredient in Dial soap and discuss its effectiveness in killing bacteria.

The Importance of Antibacterial Soap

Keeping our hands clean is essential for maintaining good hygiene and preventing the spread of harmful bacteria and viruses. Antibacterial soaps, like Dial, are specifically formulated to kill bacteria on the skin, offering an extra layer of protection against germs.

Regular soap and water can effectively remove dirt and debris from the skin, but antibacterial soap goes a step further by actively targeting and killing bacteria. This makes it particularly useful in situations where handwashing is crucial, such as before preparing food, after using the restroom, or when caring for someone who is sick.

The Active Ingredient in Dial Antibacterial Soap

The active ingredient in Dial antibacterial soap is benzalkonium chloride. This compound is a type of quaternary ammonium compound, commonly referred to as a “quat.” Benzalkonium chloride has been used for decades as an antiseptic and disinfectant due to its broad-spectrum antimicrobial properties.

How Does Benzalkonium Chloride Work?

Benzalkonium chloride works by disrupting the outer membrane of bacteria, leading to their destruction. It is effective against a wide variety of bacteria, including both gram-positive and gram-negative bacteria.

Gram-positive bacteria, such as Staphylococcus aureus and Streptococcus pyogenes, have a thick peptidoglycan layer in their cell walls. Benzalkonium chloride can penetrate this layer and disrupt the bacterial cell membrane, causing leakage of cellular contents and ultimately leading to cell death.

Gram-negative bacteria, such as Escherichia coli and Pseudomonas aeruginosa, have an additional outer membrane that provides an extra barrier of protection. Benzalkonium chloride can disrupt this outer membrane and also target the inner membrane, effectively killing gram-negative bacteria.



The Effectiveness of Dial Antibacterial Soap

Dial antibacterial soap, with benzalkonium chloride as its active ingredient, has been proven to be effective in killing a wide range of bacteria. Numerous studies have shown its efficacy against common bacteria found on the skin, including those associated with healthcare-associated infections.

One study published in the Journal of Antimicrobial Chemotherapy evaluated the bactericidal activity of benzalkonium chloride-containing products, including Dial soap, against various bacteria. The results demonstrated that benzalkonium chloride effectively killed both gram-positive and gram-negative bacteria, including methicillin-resistant Staphylococcus aureus (MRSA).

Another study published in the American Journal of Infection Control examined the antimicrobial effectiveness of Dial soap and found that it significantly reduced bacterial counts on the hands compared to non-antibacterial soap.

Benefits and Considerations of Dial Antibacterial Soap

Using Dial antibacterial soap can provide several benefits, including:

  • Effective elimination of bacteria on the skin
  • Reduced risk of spreading infections
  • Added protection during times of increased germ exposure

However, it is important to note that there are some considerations to keep in mind when using antibacterial soap, including:

  • Not all bacteria are harmful, and using antibacterial soap excessively may disrupt the natural balance of bacteria on the skin.
  • Antibacterial soap is not a substitute for proper handwashing techniques, including thorough lathering and rinsing.
  • Repeated use of antibacterial soap may lead to dryness or irritation of the skin, so it is essential to moisturize regularly.


In conclusion, the active ingredient in Dial antibacterial soap is benzalkonium chloride. This compound effectively kills a wide range of bacteria by disrupting their cell membranes. Dial antibacterial soap has been proven to be effective in reducing bacterial counts on the skin and providing an extra layer of protection against harmful germs. However, it is important to use antibacterial soap appropriately and in conjunction with proper handwashing techniques to maintain good hygiene.
