Announcement – Nitrosamine Issue

In response to the growing regulation of potential carcinogens in pharmaceutical ingredients and excipients, JMC has issued an announcement confirming the safety of our saccharin products.

Regulators such as the US FDA have recently begun regulating nitrosamines and nitrites in pharmaceuticals. In response, customers have been asking JMC to confirm the safety of our products and processes. In particular, customers have been asking whether JMC uses the Maumee process to produce Saccharin. Such questions are raised because there are concerns among customers who are aware that nitrites are used in the Maumee process. We hereby confirm to you that JMC’s Saccharin is manufactured by the Remsen & Fahlberg process, not the Maumee process. Therefore, we can also confirm that there are no concerns about nitrosamines or nitrites with JMC’s Saccharin products.

Please find below a document that details why JMC products are totally free from nitrites. We encourage you to share this with your quality team.

Please do not hesitate to contact us if you have any questions about this announcement.

Development of saccharin-based materials for cancer detection

On August 8, we announced that we had obtained a patent on functionalised derivatives of sodium saccharin and how they are manufactured.

This patent was filed through a joint study with Professors Suhng Wook Kim and Un chul Shin of Korea University’s School of Health and Environmental Science. This work was also reported in an article published on October 29 in the International Journal of Labelled Compounds and Radiopharmaceuticals. The title of the article is “Development of a 68Ga‐labelled PET tracer for carbonic anhydrase IX‐overexpressed tumors using the artificial sweetener saccharin”.

The patent concerns sodium saccharin and manufacturing methods of its derivatives combined with a ligand compound having an optional targeting action for hypoxic tumors. Sulfonamide-based substances, such as saccharin, show selective binding to Carbonic Anhydrase IX (CA IX) that occurs in tumor cells. Saccharin derivatives can therefore be used to safely and effectively diagnose cancerous tumor cells.

The results of this study confirmed the potential for saccharin derivatives to be used as new diagnostic pharmaceutical agents in addition to existing uses in various medicines, food ingredients, beverages, toothpastes, etc. as artificial sweeteners. We plan to continue joint research with domestic researchers to ensure that saccharin is commercially available as a building block for diagnostic substances in tumor cells.

JMC commits to new energy efficiency system

Last week JMC joined 30 other Korean companies, with over 40 different sites, in committing to the Korea Energy Agency’s ‘2020 Voluntary Energy Efficiency Target System’.

Participating companies committed to voluntarily improving energy efficiency and actively participating in national energy use rationalisation and greenhouse gas reduction projects.

The Korea Energy Agency expects that this project will break away from the existing regulatory-oriented policy and establish a culture of autonomous energy savings, an important aim during the economic slowdown induced by COVID-19.

JMC makes the world’s highest quality saccharin as well as a range of sulfur-based fine chemicals and chemicals for electronics such a graphene oxide and BCMB. JMC is committed to manufacturing products safely and sustainably.

JMC 67th Anniversary Ceremony

  • Name of the event: JMC’s 67th anniversary ceremony
  • Date: June 30, 2020 at 11 a.m.
  • Venue: Conference Room on the 2nd floor of JMC Ulsan Plant Main Building

The company celebrated its 67th anniversary on July 1, 2020.

Despite the auspicious day, we did not hold an official ceremony this year as part of our health and safety efforts in the aftermath of ‘Corona 19’. However, we did hold a small ceremony to recognise long-term employees as this is an important part of our company’s culture.

The CEO Jung Won-sik and 27 long-term employees (excluding 3 people in Seoul) attended the ceremony. The conference room where the ceremony was held was disinfected the previous day and all participants were thoroughly prepared to avoid possible infection by hand sterilizing and wearing masks.

Looking forwards to the 100th and even 200th anniversaries of the company, all executives and employees pledged to do their best in their roles.
