An ingredient added to dental products to remove bacteria.


Xylitol is a naturally occurring five-carbon sugar alcohol found in most plant material, including many fruits and vegetables. Xylitol-rich plant materials include birch and beechwood [1]. It is widely used as a sugar substitute and in "sugar-free" food products. The effects of xylitol on dental caries have been widely studied, and xylitol is added to some chewing gums and other oral care products to prevent tooth decay and dry mouth. Xylitol is a non-fermentable sugar alcohol by most plaque bacteria, indicating that it cannot be fermented into cariogenic acid end-products [4]. It works by inhibiting the growth of the microorganisms present in plaque and saliva after it accummulates intracellularly into the microorganism [4]. The recommended dose of xylitol for dental caries prevention is 6–10 g/day, and most adult... Read more



Indicated for use as a sugar substitute, and oral hygiene active ingredient.


There has been evidence of xylitol in dental hygiene in reducing dental caries disease and also reversing the process of early caries [ Read more

Mechanism of action

Xylitol is initially taken up by the microorganism and accumulates intracellularly. Accumulated xylitol is transported into an energy-consuming cycle, or the inducible fructose transport system. It is converted to non-metabolizable, toxic xylitol-5-phosphate via phosphoenolpyruvate: a constitutive f... Read more


Xylitol is absorbed in the small intestine via passive diffusion with a slow absorption rate [ Read more

Oral LD50 is 16500 mg/kg in rat [MSDS]. At high dosages, xylitol can cause diarrhea in children at 45 g/d and 100 g/d in adults [ Read more
