- Associate Professor Masashi Nakatani
Introduction of the discussion
Cosmetics are defined in detail by the Pharmaceutical Affairs Act as being commonly used to keep skin or hair healthy.
However, in recent years, tactile impression during use is also considered an important factor as an item for evaluating high-quality cosmetics. Many of the words used to express the sense of touch, such as “smooth”, “moist”, and “fluffy”, are also used in the catchphrases and advertising phrases that are often seen at stores, which help us select products.
Against this background, research on tactile design of cosmetics has attracted more interest than ever before. Recently, there have been reports of research on trials using tactile sensors and methods for applying to artificial skin.
Dr. Masafumi Nakatani thinks that hair damage products that deal with hair damage need to have a tactile impression can realize the effect of improving damage in addition to basic performance, and developed a simulated hair surface model to summarize tactile impression evaluation.
Finding the problem
Then, how important is tactile sensation in our lives?
Argument
Whether it is comfortable for things that has a shape, including cosmetics, is one of the criteria for choosing a product. It’s not an exaggeration to say that it will be all of the criteria, especially for those that touch our skin directly.
Many people are concerned with tactile sensations from cosmetics, clothing, furniture, towels, tissues, and toilet paper.
Naturally, it is important that each has basic performance, but it is also important how comfortable the user feels.
Conclusion
Therefore, I would like to explore what the “comfortable tactile impression” required for each product field is, and suitable experimental and analytical methods to study it.
Examining the conclusion
By studying with Associate Professor Masashi Nakatani, who has been doing various researches on tactile impression in addition to being a researcher of cosmetics development at Shiseido, I am sure that I could obtain various perspectives regarding my research and it would open up new horizons for me.
Therefore, I believe that Keio University’s Faculty of Policy Management is the most suitable place for pursuing my research and social contributions, and I am aspiring to enter your school and study in your laboratory.
