Abstract

The hydro lipid film is an emulsion of sweat and sebum that covers the surface of the human skin and affects the tribological properties of the human skin. This study investigates the effects of the composition of the sebum on the average coefficient of friction. A range of simplified sebums was developed and the friction behaviour was investigated. Five realistic sebums showed a strong variation in friction results, indicating that interpersonal differences in frictional behaviour might have their origin in differences in sebum composition. A more detailed investigation employing controlled variations of individual ingredients showed that friction is highly sensitive to the amount of squalene in the sebum. The amount of fatty acids in the sebum also showed some effects, whilst the amount of cholesterol does not appear to be relevant for the friction behaviour. The main new outcome from this study is that the composition of sebum has a significant effect on the friction response of skin in ways that are currently not yet fully understood.

皮脂特性对皮肤摩擦的影响:使用台架试验的研究

水脂膜是覆盖在人体皮肤表面的汗液和皮脂的乳液，影响人体皮肤的摩擦学性能。本研究探讨了皮脂成分对平均摩擦系数的影响。开发了一系列简化的皮脂，并研究了摩擦行为。五个真实皮脂在摩擦结果上表现出强烈的差异，表明人与人之间摩擦行为的差异可能源于皮脂成分的差异。一项更详细的调查采用控制单个成分的变化表明，摩擦对皮脂中角鲨烯的含量高度敏感。皮脂中脂肪酸的数量也显示出一些影响，而胆固醇的数量似乎与摩擦行为无关。这项研究的主要新结果是皮脂的组成对皮肤的摩擦反应有显著的影响，目前还没有完全了解。
