Expert Guidance on Extract Storage

As a general rule for storing cosmetic and food ingredients, the recommended temperature range is crucial for maintaining the stability, efficacy, and shelf life of the extract.

1. Extracts with a Storage Temperature of 25-40°C

• Can they be stored at room temperature without refrigeration? Yes, generally.
• This temperature range indicates that the extract is highly stable and designed to withstand typical tropical room temperatures (which often range from 25°C to 35°C).
• Guidance: You can store these extracts in a cool, dry room away from direct sunlight and heat sources. Ensure the room temperature does not consistently exceed 40°C (e.g., do not store near a window or in a hot warehouse). Refrigeration is not necessary and might even cause some oil-based or viscous extracts to solidify, making them harder to use.

2. Extracts with a Storage Temperature of 1-25°C

• Do they need to be kept in the refrigerator? It is highly recommended to store them in a refrigerator or a consistently air-conditioned environment.
• The maximum limit of 25°C is critical. In many tropical climates, ambient room temperature often exceeds 25°C, especially during the day.
• Risk of Spoilage/Degradation: If the extract is stored above 25°C for an extended period, it will likely:
  • Degrade: The active ingredients may lose their potency, change color, or develop an off-odor due to heat exposure.
  • Spoil: If the extract is water-based and the preservative system is sensitive to heat, or if the container is frequently opened, the risk of microbial contamination and spoilage increases significantly when stored above the recommended maximum temperature.

Conclusion:

• 25-40°C: Store in a cool, dry room (no refrigeration needed).
• 1-25°C: Store in a refrigerator (4-8°C) or a room with consistent air conditioning (20-25°C) to ensure maximum shelf life and efficacy.

General Best Practices for All Extracts:

• Always keep the container tightly sealed to prevent oxidation and contamination.
• Avoid exposing the extract to light, especially direct sunlight.
• Use clean tools when dispensing the extract to prevent introducing contaminants.
