中文摘要:

      目的 分析牙膏中薄荷醇含量对口腔清洁效果的影响。方法 以15种市售的代表性牙膏为样品, 采用气相色谱-质谱分析法测定样品中的薄荷醇含量, 并采用5点标度法使用筛选、培训后建立的专业清洁效果评价小组感官评价样品的口腔清洁效果, 通过聚类分析牙膏样品的薄荷醇含量与清洁效果的关系。结果 气相色谱测定出牙膏中的薄荷醇添加量通常在8.79~29.20 g/L之间, 专业小组评价结果显示被试样品的清洁效果在0.90~3.78之间。结论 牙膏中添加一定浓度的薄荷醇(8.79~29.20 g/L)可以达到较好的清洁效果(评分值≥3.00), 而薄荷醇浓度过高(≥62.58 g/L)或过低(≤4.27 g/L)均会降低牙膏的清洁效果(评分值≤2.30)。

英文摘要:

      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.
