Business

Green Chemical Business

Our Green Chemical business unit refers to chemicals which are obtained from renewable resources such as plants and agricultural products, its by-products, and waste, and is a general term for chemistry that replaces conventional fossil fuel-derived chemicals.

Fine Chemical Business

In the fine chemicals business, we are pursuing new possibilities for fine chemicals that we have not yet seen, with high-pressure hydrogenation reactions as the core of our business and the combination of various organic synthesis reactions and distillation purification technologies as our core values.

Contracted manufacturing

Taking advantage of the knowledge and know-how that we have accumulated over many years, we are able to provide one-stop support for development research, various laboratory prototypes, and actual machine production, and we support the realization and commercialization of various needs from many users within our domain.

Product

Castor oil fatty acid

Castor oil fatty acid is a fatty acid obtained by decomposing castor oil, and the fatty acid composition is mainly composed of about 90% ricinoleic acid, and has a small amount of linoleic acid, oleic acid, stearic acid, and 9,10-dihydroxystearic acid.

Hydrogenated castor oil (hardened castor oil)

Hydrogenated castor oil is castor oil with hydrogen added. It is a triglyceride of saturated fatty acid, and is a hard and brittle white flake-like high melting point wax.

Sebacic Acid Derivatives

Sebacic acid is a dicarboxylic acid whose main raw material is castor oil obtained from castor seed.

Castor oil oligomer

The K-PON300 series is a special fatty acid oligomer obtained from castor oil. We have the K-PON300 series, which is self-condensed with 12-hydroxystearic acid.

Castor Esters

In the K-PON series, there is the 100 series, which is a methyl ester obtained from castor oil.

Rice wax (R WAX)

Rice bran oil collected from rice bran after milling and natural wax extracted and refined from the residue after collection are one of the main products of our green chemical business.

Other oil and fat products

In our green chemical business, we sell various fats and oils in addition to castor oil.

Fine chemical products

In our fine chemicals business, we utilize the technology cultivated through many years of oil and fat production, with high-pressure hydrogenation reaction as the core of our business, and by combining various organic synthesis reactions and distillation refining technologies, resin raw materials such as polyester, polyamide, and urethane, etc are being produced.

Guerbet Products

We manufacture dimerized alcohols and their derivatives by utilizing the "alkaline fusion technology" that is an elemental technology in the production of sebacic acid that we have cultivated over many years. It is used as a raw material for cosmetics, lubricating oils, and surfactants.
