Abstract

<p>The area around the eyes creates a very strong visual impression. As eye shadow is an effective tool for improving that impression, it is used across a wide range of age groups. On the other hand, the area around the eyes is very susceptible to aging, dullness, sagging, and wrinkles, and is a concern for many. To mask the effects of aging and improve the impression made, eye shadow needs to correct and flatten wrinkles, eliminate dullness, brighten and add gloss to the area around the eyes, and create a feeling of firmness. However, irregularities on eyelids, such as wrinkles and the grooves of double eyelids, are more prominent than in other areas, making it difficult to create a flat, uniform, bright, and glossy surface. Furthermore, since eyelids frequently move forcefully during blinking, maintaining the durability of cosmetics has been a challenge. In this study, we focused on polyurethane in order to achieve a glossy and elastic eye shadow that is unaffected by movement. Our newly developed polyurethane contains highly-flexible oil-soluble soft segments and hard segments that form hydrogen bonds. Using this material, we created a gel from the oil with a reverse micelle structure. Our polyurethane-based oily-gel eye shadow not only provides gloss to aged eyelids but also offers resistance during blinking and other eye movements.</p>
