日本 大曹 DAISO  
大曹（DAISO）株式會社設立于1915年，當時稱為“大阪曹達”，在日本第一家采用當時最先進水銀法技術開始制造氫氧化鈉的企業。此后，在技術開發過程中積累了各種化學及生物技術和知識以及專業技能。這無論是過去還是將來，都是本公司創出高附加價值產品的寶貴財產。
目前本公司向世界各地廣大用戶提供從創業時就開始生產的許多基礎化工產品系列和現在的環氧氯丙烷橡膠、DAP樹脂、氯化聚乙烯等功能性化工產品，深得好評。另外，在醫藥、農藥、化妝品、食品等廣泛領域的科研中具有重要作用的硅膠、向全世界供貨的醫藥品中間體的光活性物質（對稱化合物）、以及從工業到小型民用用途廣泛的貴金屬氧化物電極等，大曹的產品，已成為各行各業中不可缺少的素材。

此外，從采用水銀法生產氫氧化鈉的生產技術開發以來，本公司重視環保的意識一脈相傳，不斷得到繼承和光大，對廢棄熒光燈管的循環利用事業等的改進環保技術和工程技術就是其具體體現。
今后，我們將以這些技術和專業技能為基礎，為早日擴大、強化我們的事業，本公司將積極推進包括在海外展開在內的與其他公司的合作等業務。同時，本公司的業務活動將從不僅僅是為了我們這一代人，還要考慮子孫后代生活的舒適和安全的角度出發，為改善地球環境做出貢獻。

Our predecessor organization, Osaka Soda, began manufacturing caustic soda in 1915. Since then, we have built up a wealth of technological and development expertise in chemicals and biotechnology. These are irreplaceable assets that we use to produce high-valueadded products for today and tomorrow.
Since our establishment, we have been dealing with many base chemical product lines and functional chemical products. These products, including epichlorohydrin rubber, DAP resin, and chlorinated polyethylene, are indispensable to many industries.
Silica gel, produced using inorganic synthesis technology, is crucial to research in a wide range of fields, including medicines and agricultural chemicals, cosmetics, and food products. We also provide optically active materials, made using of microorganisms and pure
chemical technologies, to industries worldwide, which are used as indispensable raw materials for pharmaceuticals and highly-pure pharmaceutical intermediates.
Our long-life, precious noble metal oxide electrodes are widely used around the world for industrial electrodes for salt water electrolysis, plating, copper foil manufacturing, and small electrodes for consumer electronics.
Ever since DAISO began manufacturing caustic soda using the mercury method, we have constantly taken the environment into consideration. DAISO has been putting this philosophy into action in the form of environment improvement technology and engineering technology used
in our fluorescent lamp recycling operations.
In the near future, we are looking to form alliances and expand and strengthen our international operations using our technologies and know-how. We are also working to ensure that our company operations contribute to a better environment and to improved safety and comfort for now and future generations.
The coming months will bring a number of new challenges but I am firmly convinced that together we can tackle them successfully.
