Urea that achieves low biuret, high purity, and high cleanliness.
This product is a high-purity pharmaceutical and cosmetic grade urea manufactured using the manufacturer's unique "NRML (non-reuse of mother liquor)" method and "IKS infrared drying technology." In typical urea production, the mother liquor is repeatedly reused, which can lead to the accumulation of impurities and heavy metals. In contrast, this product significantly reduces impurities by using only the initial production batch. Furthermore, the unique infrared drying technology minimizes excessive heating, achieving a biuret content of less than 0.07% to 0.5%. It has a crystalline Ultra Pure quality that complies with USP 41/43 standards, providing excellent purity and high safety. With its excellent flowable bead shape, it is suitable for a wide range of applications, including cosmetics, pharmaceuticals, supplements, and industrial uses. Additionally, a major feature is its upcycled manufacturing process aimed at zero CO2 emissions and zero waste.
