KH Neochem Co., Ltd.

KH Neochem Co., Ltd. is a Japanese specialty chemical manufacturer that positions itself as a provider of distinctive, high-quality chemical products to a wide range of industrial fields. Its business is organized around three core domains: Basic Chemicals, Performance Materials, and Electronic Materials. The company describes itself as a chemical materials maker that supplies characteristic high-quality products to diverse industries, and it frames its mission as realizing a better tomorrow through the power of chemistry. The company's core technology is the oxo reaction, also known as hydroformylation, in which olefins react with carbon monoxide and hydrogen to synthesize aldehydes. From aldehydes, KH Neochem derives a range of downstream products including alcohols, synthetic fatty acids, and esters. The company states that it is the only domestic Japanese producer able to supply certain specialty alcohols and synthetic fatty acids such as isononanol, tridecanol, and isononanoic acid, because it operates high-pressure oxo facilities in Japan. It combines this core oxo technology with organic synthesis, purification (high-purity) technology, and quality-control technology. In Basic Chemicals, KH Neochem uses oxo reactions and ester and glycol ether manufacturing technologies to supply high-quality alcohols and oxygen-containing solvents to world markets. These are used in solvents for paints, inks, thinners, and cleaning agents, as plasticizer raw materials, and as resin raw materials. In Performance Materials, the company exploits the distinctive functions of compounds obtained through oxo reactions to provide products such as raw materials for lubricating oils for alternative refrigerants that do not destroy the ozone layer, as well as materials for water-based paints and cosmetics. In Electronic Materials, KH Neochem fuses its high-purity distillation technology with ultra-trace metal analysis quality-control technology to supply high-quality products for the IT industry, including applications in liquid crystal displays and semiconductors. The company operates globally, describing itself as developing its business globally to contribute to the global environment and people's lives. It maintains a group structure with subsidiaries and affiliates, and publishes an integrated report, the KH Neochem Report, under the theme of aiming to be a specialty chemical company that shines globally. Its shares are listed on the Tokyo Stock Exchange. The company also engages in sustainability management, seeking to balance contribution to a sustainable society with enhancement of corporate value, and it pursues open innovation with companies, research institutions, and universities in Japan and overseas.

KH Neochem Co., Ltd. is a Japanese chemical manufacturer whose identity is closely tied to oxo reaction (hydroformylation) technology. The company describes oxo reaction as its core technology: olefins react with carbon monoxide and hydrogen to synthesize aldehydes, from which alcohols, synthetic fatty acids, esters, and other derivatives can be produced. By combining this core reaction with organic synthesis, purification (high-purity) technology, and quality-control technology, KH Neochem has established proprietary technologies and supplies materials used in everyday life and industry. The company states that it is the only producer in Japan capable of supplying certain specialty alcohols and synthetic fatty acids, including isononanol, tridecanol, and isononanoic acid, because it operates high-pressure oxo facilities domestically. This capability underpins its Basic Chemicals business, where it supplies high-quality alcohols and oxygen-containing solvents to world markets for use in paints, inks, thinners, cleaning agents, plasticizer raw materials, and resin raw materials. Over time, KH Neochem has built out two further business domains alongside Basic Chemicals. In Performance Materials, it leverages the distinctive functions of compounds obtained through oxo reactions to provide products such as raw materials for lubricating oils used with alternative refrigerants that do not destroy the ozone layer, as well as materials for water-based paints and cosmetics. In Electronic Materials, it applies its high-purity distillation technology and ultra-trace metal analysis quality-control technology to supply high-quality products for the IT industry, including liquid crystal and semiconductor applications. The company operates as a group with subsidiaries and affiliates and describes itself as developing its business globally to contribute to the global environment and people's lives. It publishes an integrated report, the KH Neochem Report, and frames its long-term direction around aiming to be a specialty chemical company that shines globally. Its corporate communications reference a medium- to long-term management plan, VISION 2030, and a Fifth Medium-Term Management Plan, as well as corporate principles including a 5C Credo and a code of conduct. The company also pursues sustainability management, seeking to balance contribution to a sustainable society with enhancement of corporate value, and it engages in open innovation with companies, research institutions, and universities in Japan and overseas. Its shares are listed on the Tokyo Stock Exchange.
