Chemicals That Lower Testosterone In Mouthwash

Welcome to this article looking at the chemicals that lower testosterone in mouthwashes, if you’ve visited my site before (or Mouthwashhad a bit of a look around today), you may have noticed that there are a few different articles looking at the chemicals that lower testosterone in other personal care and hygiene items.

Sadly mouthwashes are just one of many hygiene products that do contain these toxic chemicals. If you haven’t seen the other articles on the products that contain these chemicals, check out this Chemicals That Lower Testosterone – Where Are They Found Article to get a feel for the other products that present an issue.

If you’re reading this article, I guess you likely have an interest in making sure you have higher testosterone levels and are aware how lower T negatively impacts your health.

If you’re unsure/ want a reminder of how Testosterone and health are linked, check out these articles on Testosterone And Health where we look at how low T negative impacts your health and the benefits gained from healthy/ higher T levels.

The Chemicals That cause An Issue

There a number of toxic chemicals that can be found in mouthwashes, with the most common ones being as follows:

  • Alcohol
  • Fluoride
  • SLS/ Sodium Lauryl Sulfate
  • Triclosan
  • Parabens
  • Quats
  • Sodium Saccharin
  • Cocamidopropyl Betaine
  • Formaldehyde
  • Chlorhexidine
  • Cetylpyridinium Chloride
  • Hexetidine (oraldene)
  • Methyl Salicylate

Now not all the above chemicals negatively impact your testosterone levels or are endocrine disruptors. As this article is about the chemicals that lower testosterone found in mouthwashes, we’re going to focus on the chemicals that can be considered endocrine disruptors & increase estrogen I would however researching the other chemicals listed above, as what they do to your body isn’t pleasant!

What Are Endocrine Disruptors?

You probably noticed that I mentioned endocrine disruptors above as something that lower testosterone, so I thought I’d give Stop Warning Signa quick overview of what they are, as it’s’s not a term I became aware of until I began my own research in to the things that lower T.

Endocrine disruptors are chemicals that can interfere with how your hormonal/ endocrine system works, these disruptions can result in incorrect hormonal production & imbalance, including lowered testosterone production.

The issue doesn’t just end there though, these imbalances can potentially cause even more serious health issues like, the development of cancerous tumors, birth defects & other developmental disorders. Any bodily systems that are controlled by hormones, can potentially be negatively impacted by endocrine disrupting chemicals.

So hopefully you now have a greater understanding of what endocrine disruptors are and the risks they can pose to your health, including being chemicals that lower testosterone production. So now let’s take a look at these chemicals that are endocrine disrupting found in mouthwash and the other chemicals that lower testosterone in mouthwash.


The problem is that alcohol lowers testosterone production when ingested, while I agreed the amount of alcohol you’re likely to swallow from mouthwash in minimal, the issues with mouthwash don’t end there and as you’ll see below it isn’t a necessary ingredient.

Alcohol is a key ingredient of most mouthwashes due to the strong tingling sensation which people associate with cleanliness and the powerful antibacterial qualities. The issue is that the alcohol is so powerful it destroys the good bacteria as well. The alcohol in mouthwash is also a known carcinogen and it’s believe that there is now sufficient evidence to show that mouthwashes that contain alcohol can contribute to the increased risk of developing oral cancer, so plenty of reasons to use natural alcohol-free mouthwash or an alternative like gargling salt water.


Studies have shown that continual high exposure to fluoride can badly damage the male reproductive system, including reducing testosterone production, sperm motility, sperm quality and overall fertility. There have been several highly controlled studies conducted and they have consistently found that direct exposure of fluoride to the testes or semen inhibits testosterone production and damages sperm.


Sodium lauryl sulfate, which often appears as SLS, SLES or sulfates on ingredients lists, so if you see an ingredient with sulfate as part of the name remember to avoid! So SLS is a detergent, surfacant & emulsifier. It’s a key ingredient in thousands of products which includes cosmetics, hygiene, oral care and industrial cleaners. It’s often mistaken as being a healthy/ safe ingredient as it originates from coconuts; but it’s the manufacturing process that is gone through to create SLS that results in it becoming toxic. With it becoming toxic it’s a chemical that lowers testosterone and a danger to your endocrine system.

SLS poses a threat to your testosterone production and wider endocrine system as it breaks down the moisture barrier of your skin. This breakdown enables other toxic chemicals & substances (like the other we’ve listed) to penetrate the skin and makes it easier for other chemicals that lower testosterone to make their way in to the body. SLS breaks down the moisture barrier so greatly, it is believed to make the skin 100 times easier to permeate and penetrate. poison

The other key issue with SLS is, that when combined with other chemicals it becomes a “nitrosamine”. Nitrosamine is powerful carcinogen and is a toxin to the body.

There have been studies conducted in to the effects of SLS exposure, these studies have found links to organ toxicity, skin & eye irritation, reproductive & developmental toxicity and reduced testosterone production/ endocrine disruption.


Triclosan is an antibacterial chemical which helps to fight plaque and gingivitis; however this protection comes at a pretty high cost! Triclosan has been linked to issues with antibiotic resistance & our old friend/ recurring enemy endocrine disruption. As we’ve covered endocrine disruption can cause multiple health issues including lowering testosterone production.


This chemical is used in wide range of skin, cosmetics and oral care products, including mouthwashes. You will see parabens make frequent appearances in my Chemicals That Lower Testosterone Articles – It is utilised as a preservative in products, the issue when it comes to lowering testosterone production is two fold. It mimics estrogen in the body, lowering your ratio of testosterone to estrogen. Parabens are like most the other chemicals on this list are endocrine disruptors.

Research ran by the US Environmental Protection Agency has linked methyl parabens to multiple health issues, this includes metabolic, hormonal, neurological and developmental disorders. Parabens don’t just negatively impact testosteorne and the endocrine system but are also a risk to multiple areas of your health.


Quarternary Ammonium Compounds, or Known as “quats” for short. Again they are a common ingredient cosmetic and oral care items of they are usually responsible for the “slippery feel” in liquids. They also have anti-microbial properties which is what has led to them being added to cleaning products and others like mouthwashes.

QUATS can cause multiple health issues, these include respiratory issues and skin irritation. What we are more interested in as far as being a chemical that lower testosterone is QUATS like benzalkonium chloride, this is a common ingredient in mouthwashes. It’s shown to be yet another endocrine disruptor.

Alternatives organic sign

To avoid these chemicals you need to look for brands that promote themselves as being organic or free of toxic chemicals. You also have some other options as mentioned such as gargling salt water, which will do part of the job of a mouthwash.

I’ll be putting an article together soon, review my recommended mouthwashes that don’t contain chemicals that lower testosterone, so keep an eye out for that in the near future.

Final Thoughts & Future Articles

I hope you have found this article on chemicals that lower testosterone in mouthwashes useful. You should now have an understanding of how dangerous the chemicals are in most mouthwashes and why they lower T production.

As I mentioned above, I will be creating an article reviewing my top recommended mouthwashes that don’t contain chemicals that lower testosterone, so keep an eye out for that. I still have some more articles to go on other products that contain chemicals that lower T, so keep an eye out for them, so you can continue knowing what to avoid. If you have any queries in regard to this article, things that can lower T or testosterone production as a whole, just drop me a comment below and I’ll get back to you.

  1. Wow, very interesting article. I had no idea there were so many chemicals and bad stuff in mouth wash! I am very excited to read your post on better options, when you get it written. My husband uses mouth wash every day. I prefer to use coconut oil and swish for 5 minutes. That has worked really well for me and can actually reverse effects of gum disease and cavities.

    1. Hi Amber,

      Yeah sadly these chemicals appear in multiple oral and skin care items. I’ll be putting that article out soon, yeah coconut oil is good, as is salt water, there are still certain things you miss using those options, so I’ll be advising of some mouthwash brands free of chemicals that lower testosterone, so yeah keep an eye out or that article.
