Based on your formulation and the image, the green flakes are most likely coming from the Olive Oil you used. Extra Virgin Olive Oil contains chlorophyll, which gives it a green color. When mixed with other ingredients, especially powders like Kaolin or Charcoal, or if the emulsion isn't stable, the oil (and its green pigment) can separate or react, appearing as green flakes or streaks.

To fix this:

Try replacing the Extra Virgin Olive Oil with a refined olive oil (which has less chlorophyll) or another colorless or pale oil like mineral oil or sunflower oil.
Ensure all ingredients are mixed thoroughly and the base cream is compatible with the oils and powders.
