General Storage Requirements
Standard Environment: Maintain a temperature below 25°C and a relative humidity below 65%; ensure the storage area is dry and well-ventilated.
Basic Protection: Keep containers tightly sealed at all times. Protect from exposure to sunlight or rain, and avoid direct contact with acids, bases, or highly volatile substances.
Packaging Compatibility: Excipients prone to oxidation or moisture absorption must be stored in moisture-proof and oxygen-barrier packaging, such as pharmaceutical-grade polyethylene (PE) bags combined with aluminum foil composite films.
Specific Controls for Specialized Excipients
Hygroscopic (Moisture-Absorbing) Excipients: Substances such as lactose, dextrin, or effervescent-type excipients must be stored separately in a dry area, with humidity strictly controlled below 60%.
Photosensitive (Light-Sensitive) Excipients: Substances such as Vitamin C or Polysorbate 80 must be stored in amber-colored, light-resistant containers or aluminum foil packaging to prevent exposure to direct sunlight.
Liquid/Volatile Excipients: Must be kept in tightly sealed containers and stored in a separate area from solid excipients to prevent cross-contamination or odor transfer.
