While vitamin E oil itself doesn't expire, its potency decreases over time. This means the oil might not be as effective after a certain period. The industry standard shelf life for vitamin E oil is typically 36 months from the date of manufacture when stored in optimum conditions. It will gradually darken over time, indicating potential degradation.
Here are some factors that influence the shelf life of vitamin E oil:
- Storage conditions: Storing vitamin E oil in a cool, dark, and dry place can extend its shelf life. Avoid direct sunlight and heat exposure.
- Exposure to air: Exposure to air can lead to oxidation, which reduces the oil's potency.
- Type of vitamin E oil: Different types of vitamin E oil might have varying shelf lives.
Here are some tips for preserving vitamin E oil:
- Store in a dark, cool, and dry place.
- Use an airtight container to minimize exposure to air.
- Avoid exposing the oil to direct sunlight or heat.
While using vitamin E oil past its expiry date might not be dangerous, its effectiveness might be compromised.
