AJIDEW NL-50 is a natural humectant derived from L-Glutamic acid. Known to be abundant in human skin as a component of NMF (Natural Moisturizing Factor), AJIDEW NL-50 helps keep skin and hair fresh-looking. AJIDEW NL-50 can absorb water up to 70% of its dry weight. Due to its hygroscopic and moisturizing properties, AJIDEW NL-50 is especially useful as a humectant for reducing skin tightness caused by cleansing and improving hair manageability.
