Safety and Quality Management

Safety and high quality are secured by various inspections.
The through health management is the foundation of HOSHI CORPORATION.
We cannot be enough to make effort about manufacturing products.
This is our safety and quality management.

Safety and quality management of our domestic plants are based on GMP (Good Manufacturing Process) in all manufacturing processes from stock acceptance to finishing products. Hereafter, we explain three example processes of “stock acceptance”, “production” and “filling” to build your better understanding.

Stock Acceptance

Taking advantage of the accumulated know-how, we procure safe and high quality ingredients from various channels.
After materials have received, they undergo not only strict inspections by all sorts of equipment and also have been checked looks and touch by sophisticated inspectors.
We firmly confirm safety and quality by the data and human senses.

Production

In a manufacturing area, clean environment where satisfies the level of manufacturing ordinary medicines has always maintained.
Dusts and dirt in the air is carefully removed by air purifiers, ozone pasteurizer and UV pasteurizer. Materials are measured both on the date before and the same date of manufacturing date.
Human errors are prevented by measuring different dates, time and staffs. The mixed ingredients undergo various checks such as fungus inspection by using liquid chromatography, firmness and the viscosity check by rheometer (viscometer), and looks and smell check by trained inspectors.

Filling

At the process of filling up a container with cosmetics, we introduced removable stainless pipes.
This can perform through health management by removing pipes periodically for washing and sterilization.
Moreover, the total weight checker with the metal detector is used for inspection. Materials which passed this inspection are voluntary conducted destructive inspection.
The propriety for delivery is judged after 48 hours cultivation. Only materials which passed this test become our product.
