Objective To analyze the effects of menthol content in toothpaste on the sensation of oral cleaning. Methods Fifteen kinds of representative toothpastes were taken as test samples in this paper. Gas chromatography-mass spectrometry (GC-MS) analysis method was used to determine menthol content in toothpaste and a specialized sensory panel was also screened, trained and established to evaluate the sensation of oral cleaning by using 5-point scale method. Results The GC-MS results showed that the additive amount of menthol in most of toothpaste was usually between 8.79 g/L and 29.20 g/L while the panel’s results showed that the oral cleaning sensation of test samples was between 0.90 and 3.78. Conclusion A certain content of menthol (8.79~29.20 g/L) in toothpaste had good effect of oral cleaning while low (≤4.27 g/L) or high (≥62.58 g/L) menthol content led to bad effect of oral cleaning.
