Tag: Expired castor oil

The typical shelf life for castor oil is between 12 and 24 months, but this can be significantly shortened by improper storage. Recognizing the subtle and overt signs of spoilage is crucial to prevent the use of degraded oil, which may lose its effectiveness or cause adverse skin reactions. Knowing what to look for can protect your health and your investment.

Over 90% of castor oil's composition is ricinoleic acid, which gives it its thick texture and therapeutic properties but also makes it prone to oxidation. Knowing how to know if castor oil is rancid is essential, as using expired oil can lead to skin irritation and reduce its effectiveness.
