Triclosan and Colgate Toothpaste

What You Need to Know

Updated: January 2025

In 2017, I wrote about the dangers of triclosan, a controversial ingredient used in many personal care products, including Colgate Total toothpaste. Since then, significant changes have occurred regarding triclosan’s use in consumer products. Here’s what you need to know.

What Is Triclosan?

Triclosan is a chemical with antibacterial properties that was once widely used in toothpaste, soaps, and body washes to help reduce bacteria. However, concerns have grown over its safety. Research has linked it to:

• Disruption of thyroid hormones
• Immune system suppression
• Contribution to antibiotic resistance
• Potential negative effects on heart and muscle function

Because of these risks, the FDA banned triclosan from hand soaps and body washes in 2017. While toothpaste was not initially included in the ban, many manufacturers have since removed the ingredient voluntarily (source).

Colgate Total and Triclosan: Then vs. Now

When I originally wrote this post in 2017, Colgate Total toothpaste still contained triclosan and defended its use, citing studies that claimed it reduced gum disease more effectively than other toothpastes. However, the studies supporting its safety were criticized for being company-funded and not accounting for long-term risks.

The good news? In 2019, Colgate updated its formula and removed triclosan entirely. The new version, called Colgate Total SF, uses a stannous fluoride formula instead (source). This is a positive step toward reducing exposure to potentially harmful chemicals in everyday products.

If you still have an old tube of Colgate Total with triclosan in your home, it’s best to toss it out and switch to the updated formula or another triclosan-free toothpaste.

Why Avoid Triclosan?

Even though it has been phased out of most products, understanding why it was controversial can help you make informed choices. The delicate balance of bacteria in your mouth and body is essential for health. Triclosan’s indiscriminate killing of both good and bad bacteria can disrupt this balance, potentially leading to issues like bad breath, dry mouth, and reduced immunity.

For safer options, always read ingredient labels and choose products free of triclosan and other harmful chemicals.

How to Check for Harmful Ingredients

Triclosan is no longer common in personal care products, but it’s always wise to check labels for harmful ingredients. Look for certifications like “clean” or “non-toxic” products. And remember: when it comes to your health and that of your family, it’s better to be safe than sorry.

Final Thoughts

The removal of triclosan from Colgate Total toothpaste is a victory for consumers and a step toward safer personal care products. While it is no longer a concern in most products, it’s important to remain vigilant about the ingredients we use daily.
