Seiwa Kasei Co., Ltd. Develops 100% Naturally Derived Amino Acid Derivative Achieving "Long-Lasting Moisturizing"

Seiwa Kasei Co., Ltd., a company engaged in the research and manufacturing of cosmetic raw materials (Headquarters: Higashiosaka City, Osaka Prefecture; Representative Director: Masato Yoshioka), has developed a new 100% naturally derived amino acid derivative, "Amitose® R-green," which achieves long-lasting moisturizing (to be launched from April 2026).

Key Features of Amitose R-green: 1. Long-lasting moisturizing through the fusion of glycerin and arginine. 2. Comfortable feel, moisturizing yet non-sticky. 3. 100% naturally derived sustainable design for global markets.

Background of Amitose R-green Development: In recent years, the cosmetics market has demanded not merely "moisturizing" but "sustained moisturizing" that allows users to feel hydration immediately after washing and maintains a comfortable sensation over time. Furthermore, with the expansion of "Skinification" – applying skincare concepts to hair and scalp care – there is growing interest in multi-functional ingredients that can approach skin, hair, and scalp from various angles. In the global market, sustainability, such as environmental consideration and naturally derived design, is also a crucial factor.

Against this backdrop, our company developed "Amitose® R-green," an amino acid derivative that achieves both long-lasting moisturizing through the fusion of glycerin and arginine and sustainability.

How to Use Amitose R-green / Application Scenes: Amitose R-green can be formulated into a wide range of product types, including lotions, serums, creams, shampoos, and conditioners. As a multi-functional ingredient, it can also be applied to all-in-one formulations and multi-care designs, in addition to skincare, haircare, and scalp care products. Furthermore, being 100% naturally derived, it supports sustainable formulations for the global market.
