Soapwort Extract
Also known as: Saponaria extract
Soapwort saponins can irritate the gastrointestinal tract and at higher exposures can be hemolytic. Use as a foaming agent in foods is traditional but not broadly authorized as a food additive in the U.S.
What it is

Foaming/whipping agent in some traditional foods (e.g., halva, certain Middle Eastern desserts) and natural detergent.
Why it's flagged
- GI irritation at high doses
- Hemolytic potential
- Limited modern food-additive authorization
