Sangi Co., Ltd. (pronounced “sun-ghee”) specializes in applications of the calcium phosphate compound hydroxyapatite, the natural, highly biocompatible substance of our teeth and bone. As pioneers, we are proud to have developed the world’s first remineralizing toothpaste, using Sangi’s own proprietary hydroxyapatite, as early as 1980, and to have launched the world’s first nanotech toothpastes in 2003, by reducing the ingredient size from 3-figure to 2-figure nano-scale. We have gone on to develop a wide range of hydroxyapatites for use in various fields, including drug delivery systems, antimicrobial agents, industrial catalysts, functional foods and cosmetic products, in addition to dental materials. Sangi takes its name from the three principles (“San-gi”) of Mencius: “The timing of the heavens, the riches of the earth, and the harmony of men.” Our motto is “Unbiased, uninsisting, unconfined” – inspiring us to be always open to new challenges and ideas. And our aim is to support the regenerative powers of people and of nature, to create a healthier, more beautiful world.
