摘要

对化妆品行业来说，评估化妆品进入皮肤的深度和速度是非常重要的。然而，传统的测量这些参数的方法存在一些缺陷。在本研究中，采用了基于硅基发射极的太赫兹飞行时间法进行评估。液体对猪皮的渗透是通过太赫兹脉冲照射在猪皮上的传播时间来测量的，其中液体中的甘油浓度是不同的。

Evaluation of Cosmetic Liquid Penetration Using Terahertz Time-of-Flight Method

It is important to evaluate the penetration depth and speed of cosmetics into the skin for the cosmetic industry. However, the conventional method for measuring those parameters has some drawbacks. In this study, a terahertz time-of-flight method with Si-based emitter was applied for evaluation. The penetration of the liquid into a pig skin was measured as a travelling time of the THz pulses irradiating on a pigskin, where the glycerin concentration in the liquid was varied.
