Koken Co., Ltd. manufacture cosmetic raw materials focus on collagen, botanical materials and also freeze-drying products. Collagen(insoluble collagen) is a protein that is abundant in animal skin(dermis), but it is usually not soluble in water or acid. Therefore, utilization of collagen as a cosmetic ingredient is very limited, but in 1978 we established unique technology to solubilize collagen. As a result collagen has come into wide use as cosmetic ingredient as it is. We have also succeded to manufacture botanical (fruit) powders, extracts, and glycoprotein mucin(from squid), and collagen sheets by applying lyophilization (freeze-drying) technology. As a manufacturer of cosmetic raw materials, we will continue to endeavor to provide useful materials.
