Seiwa Kasei Develops 100% Natural-Derived Amino Acid Derivative for 'Long-Lasting Moisturizing'

Seiwa Kasei Co., Ltd. (Headquarters: Higashiosaka, Osaka; President: Masato Yoshioka), a company engaged in the research and manufacturing of cosmetic ingredients, has developed 'Amitose® R-green,' a new amino acid derivative that achieves 100% natural-derived long-lasting moisturizing (scheduled for release in April 2026).

Features of Amitose R-green: 1. Long-lasting moisturizing through the fusion of glycerin and arginine. 2. Comfortable texture that is 'moist' but 'not sticky.' 3. 100% natural-derived sustainable design compatible with the global market.

Development Background: In the recent cosmetics market, there is a demand for 'sustainable moisturizing' that provides immediate hydration after cleansing and maintains comfort over time. Furthermore, with the spread of 'skinification'—applying skincare concepts to haircare and scalp care—there is growing interest in multifunctional ingredients that can approach skin, hair, and scalp from multiple angles. Additionally, in the global market, sustainability, such as environmental consideration and natural-derived design, has become a crucial element. Against this backdrop, we developed 'Amitose® R-green,' an amino acid derivative that combines long-lasting moisture with sustainability.

Usage and Application Scenes: Amitose R-green can be formulated into a wide range of products such as lotions, serums, creams, shampoos, and conditioners. As a multifunctional ingredient, it can also be applied to all-in-one formulations and multi-care designs. Furthermore, being 100% natural-derived, it supports sustainable formulations aimed at the global market.
