JMC (originally the Jeil Moolsan Company) was established in 1953 and is a world leader in the field of saccharin and sulfur-based fine chemicals. JMC became part of the KISCO group in 2004. JMC is a large-scale manufacturer of saccharin, a safe, artificial sweetener that enables a drastic reduction in sugar content. JMC supplies saccharin to the world’s largest quality-oriented multinational food and medicine producers. JMC produces saccharin using the traditional Remsen and Fahlberg Process which was discovered in 1879. JMC is the only company that produces all of the high purity raw-materials for Saccharin such as OTSA (ortho-Toluenesulfonamide) on its own production lines. No organic solvents are used during the production process of Saccharin and JMC’s complete, vertical integration ensures the highest purity materials which delivers the highest quality saccharin available. JMC’s saccharin meets the food safety standard, FSSC 22000. JMC also produces fine chemicals for applications such as florescent pigments, pharmaceutical intermediates, electronics, plastics and agricultural products.

JMC has applied its existing expertise and developed the ability to mass-produce next-generation nanomaterial products such as graphene oxide. JMC is continuously working to become a world-leading company by understanding the needs of its customers.

Based in Korea, our business is global. JMC – creating sweetness and pure chemistry.

Our Products
