Question: 1 / 1775

What is the primary role of a humectant in dental products?

To enhance flavor

To prevent moisture loss

The primary role of a humectant in dental products is to prevent moisture loss. Humectants are substances that attract and retain moisture, which is particularly important in products like toothpaste, mouthwash, and other oral care formulations. By maintaining moisture, humectants help to keep the consistency of the product stable and effective, ensuring that the formulation does not dry out or become crumbly, thereby preserving its efficacy when used. This property is especially beneficial in preventing the mouth and other soft tissues from becoming dry, which can contribute to discomfort or oral health issues.

While other options reflect important functions within dental care, they do not specifically relate to the role of a humectant. Enhancing flavor, whitening teeth, and promoting healing are separate functions that may involve different ingredients or mechanisms in dental products.
