土井：10.1111/j.1741-2358.2012.00639.x组织调理剂的动态粘弹性和增塑剂相容性目的：动态粘弹性是组织调理剂最重要的特性之一。增塑剂从组织调理剂中的浸出可能导致这些材料的动态粘弹性的变化。本研究的目的是确定商业组织调理剂的动态粘弹性和增塑剂可溶解性。材料与方法：本研究中使用了五种商业组织调理剂：COE Comfort（CC）、Fit Softer（FS）、Hydro-Cast（HC）、Soft Conditioner（SC）和Visco-Gel（VG）。将每种材料的五个样本储存在37 ℃蒸馏水中。在浸泡后0、1、3、7和14天，使用动态力学分析仪和高效液相色谱法测量每个样品的动态粘弹性和增塑剂浸出。使用单因素方差分析和StudentNewmanKeuls检验（α = 0.05）分析数据。结果：不同材料的动态粘弹性和增塑剂溶出量存在显著差异。所有材料的动态粘弹性随时间的增加或减少显着。动态粘弹性的快速变化是明显的第1天后，水浸。材料CC记录了最高水平的增塑剂浸出。结论：这些结果表明商业组织调理剂的动态粘弹性受到增塑剂浸出的影响。然而，这些影响是有限的。
doi: 10.1111/j.1741-2358.2012.00639.x The dynamic viscoelasticity and plasticizer leachability of tissue conditioners Objectives: Dynamic viscoelasticity is one of the most important characteristics of tissue conditioners. Leaching of plasticizer from tissue conditioners may cause changes in the dynamic viscoelasticity of these materials. The purpose of this study was to determine the dynamic viscoelasticity and plasticizer leachability of commercial tissue conditioners. Materials and methods: Five commercial tissue conditioners were used in this study: COE Comfort (CC), Fit Softer (FS), Hydro-Cast (HC), Soft Conditioner (SC) and Visco-Gel (VG). Five specimens of each material were stored in 37 degrees C distilled water. The dynamic viscoelasticity and plasticizer leaching of each specimen were measured at 0, 1, 3, 7 and 14 days after immersion using a dynamic mechanical analyzer and high performance liquid chromatography. Data were analyzed using one-way anova and StudentNewmanKeuls test (alpha = 0.05). Results: Significant differences in dynamic viscoelasticity and plasticizer leaching were found among the materials. The dynamic viscoelasticity of all materials increased or decreased significantly with time. Rapid changes in dynamic viscoelasticity were evident on day 1 after water immersion. The material CC recorded the highest level of plasticizer leaching. Conclusion: These results suggest that the dynamic viscoelasticity of commercial tissue conditioners is affected by plasticizer leaching. However, these effects are limited.
