Ingredients in a Mouthwash

If you have ever read the label of your mouthwash bottle, you would likely be lost in the sea of ingredients that sound more like a science experiment than something you would want to swish in your mouth.

However, all of these ingredients are safe for use and often have a specific purpose. Let’s breakdown some of the common ingredients that can be found in most big brand mouthwash products:

1. Fluoride: A superstar for tooth enamel, fluoride helps to rebuild weakened tooth surfaces and fights off cavity-causing bacteria.
2. Alcohol: This is used as an antiseptic as alcohol helps to kill bacteria, but it’s also the reason why some mouthwashes can give that burning sensation. Most brand now contain alcohol-free versions of its mouthwash for those who dislike the sensation of it.
3. Essential Oils: Ingredients like eucalyptus and peppermint oils not only provide flavor but also have antibacterial qualities.
4. Preservatives and Stabilizers: These prevent the ingredients in a mouthwash from breaking down over time, extending its shelf life.
5. Hydrogen Peroxide: Found in whitening mouthwashes, this chemical acts as a bleaching agent.
6. Xylitol or Sorbitol: These are sugar alcohols that sweeten the mouthwash without causing tooth decay.
7. Coloring Agents: These give your mouthwash that eye-catching hue but are often the culprits if your clothes are stained.
8. Chlorhexidine: Better known as chlorhexidine gluconate, this is common in prescription mouthwashes as it is a potent antibacterial agent.
9. Water: The unsung hero of any formula, water serves as the base in which all these ingredients can mix.

Depending on the type of mouthwash—cosmetic mouthwash, fluoride mouthwash, antiseptic mouthwash and natural mouthwash—the ingredients can vary. For instance, prescription mouthwash would contain chlorhexidine (also known as chlorhexidine gluconate), an ingredient not found in cosmetic or fluoride mouthwash.

Understanding the ingredients in your mouthwash can help you choose the right one for your needs and also save your shirt from potential stains!

How Mouthwash Stain Clothes

So you’ve had a mini-disaster: the bottle slipped, and now you’ve got a splash of mouthwash on your favourite outfit. But what actually turns that magical liquid into a mini fashion disaster?
