Why is sorbitol solution used in mouthwash?

Lubrication: Sorbitol acts as a humectant, retaining moisture on the surface of the oral tissues. This lubricating property creates a smooth sensation, leaving your mouth feeling refreshed.

Sweet taste: Sorbitol is approximately 50-60% as sweet as sucrose (table sugar), providing a pleasant taste without the use of fermentable sugars that could contribute to tooth decay.

Sugar-free option: Sorbitol is free from fermentable carbohydrates that oral bacteria metabolize into acids. This makes it a suitable ingredient for sugar-free mouthwashes, preventing potential harm to dental health.

Viscosity: Sorbitol contributes to the mouthwash's viscosity, influencing the texture and consistency of the liquid.

Low toxicity and cariogenic potential: Sorbitol is considered non-toxic and safe to use in mouthwash formulations, posing little risk to oral tissues. It also has low cariogenic potential, meaning it doesn't readily contribute to tooth decay when used according to the recommended guidelines.

Overall, sorbitol serves multiple functions in mouthwashes, including providing sweetness, lubrication, texture, and non-cariogenic benefits, enhancing the overall sensory and functional properties of the product.
