Question
When making a toner using French Pine Bark, the mixture turns a dark, cola-like color and precipitation occurs at the bottom and sides of the bottle. What is the cause and how can this be resolved?
Answer
Hello,
Regarding the issues you encountered while making the French Pine Bark toner, specifically the dark color and precipitation, here is an explanation:
- Product Color: The dark, cola-like color is a normal characteristic of French Pine Bark (Pycnogenol), which is naturally very dark. This is usually mentioned in the product details.
- Precipitation Issue: The precipitation of French Pine Bark at the bottom and sides of the bottle is due to incomplete dissolution. Although French Pine Bark is water-soluble, it requires sufficient assistance in dispersing and dissolving properly.
Solution:
According to the staff's recommendation, you can fix this issue by:
- Slightly warming the mixed formulation (it doesn't need to be very hot).
- Using a mixer or stirrer to stir/mix at a low speed (not exceeding 500 RPM) for approximately 15 minutes.
Doing this will help the French Pine Bark disperse and dissolve completely in the water. A slightly warmer temperature will facilitate the dissolution process.
