Precautions for Handling: Plastic ampoules: Since an oxygen absorbent is enclosed to maintain stability of the product, do not remove the outer wrap until immediately before use. Use immediately after opening.
Do not use if there is any vapor inside the outer wrap, or if there is color, turbidity, or crystals in the liquid.
Stability testing: The results of a long-term storage test (25°C, 3 years) using the final container product showed that the appearance and strength are in compliance with the specification and that HISHIPHAGEN remains stable for 3 years under normal market conditions.
