Wild Yam Extract Dissolution Issue

Based on the product information for Wild Yam Extract (Diosgenin 95%), storing the product in a cool place like a refrigerator for a long time can indeed cause sedimentation.

To ensure the ingredient dissolves completely in oil, it is recommended to follow these steps:

1. Take the Wild Yam Extract out of the refrigerator.
2. Leave it at room temperature for 3 hours before mixing.
3. Mix the extract into the oil phase of your formulation.
4. Heat the mixture to 60 degrees Celsius for a short period (no more than 10 minutes) to help the ingredient dissolve completely.

So, yes, not letting the extract return to room temperature after refrigeration is likely the reason it did not dissolve properly. Following the recommended procedure should resolve the issue.
