Xylitol is widely used as a sugar substitute in various food products, particularly in chewing gum, candies, and baked goods, due to its similar sweetness to sugar but with fewer calories. It is also beneficial for dental health, as it helps reduce the risk of cavities and tooth decay by inhibiting the growth of harmful bacteria in the mouth. In pharmaceuticals, xylitol is often included in oral care products like toothpaste and mouthwash for its protective effects on teeth. Additionally, it is used in nasal sprays and syrups to alleviate dryness and improve moisture retention. Xylitol's low glycemic index makes it suitable for diabetic-friendly products, providing a safe alternative to sugar without causing significant spikes in blood glucose levels. Its humectant properties also make it a common ingredient in cosmetics and skincare products to maintain hydration and improve texture.
