Zinc chloride

What is it?

Zinc chloride is derived from purified zinc from the Earth.

What does it do?

In its aqueous state, such as in a mouthwash, zinc chloride neutralizes the odor caused by bad breath germs for long-lasting fresh breath. It also works by controlling the growth of bad breath bacteria. It is also used in other temporary breath fresheners such as mints, sprays, lozenges and even chewing gum.

How is it made?

Our Stewardship Model guides us to select ingredients which have been processed in a manner that supports our philosophy of human and environmental health.

Tom’s of Maine uses an aqueous form of zinc chloride, which is created by combining zinc with hydrochloric acid.

What are the alternatives?

Alcohol, common in many mouthwash brands, is an alternative. However, it doesn’t meet our stewardship standards and can cause an uncomfortable burn for some consumers. For consumers who want to avoid this ingredient, Tom’s of Maine also produces a mouthwash that does not contain this ingredient. We feel it is important to offer individuals a choice.

Is this the right option for me?

Zinc chloride has a long safe history of use as an effective mouthwash ingredient. The Food and Drug Administration (FDA) has approved its use as a drug active in the astringent indication in oral care Over-the-Counter (OTC) drug products when used at concentrations of 0.1–0.25% in aqueous solution.1

Many experts believe the addition of zinc ions in mouthwash is the best way to help reduce germs  that produce sulfur gases, a major component of bad breath. Using mouthwash alone, however, is not a substitution for daily brushing and flossing.

Tom's of Maine recognizes that no two people are alike, and even with naturally derived ingredients, some individuals may develop an allergic reaction that is unique to them. As with any product, be sure to discontinue use if you experience discomfort or other indications that the product may not be appropriate for your individual body chemistry.
