Quillaia extract type 2
Quillaia extract type 2 · 999(ii)INS 999(ii)
Used as an emulsifier — Codex also lists it as foaming agent.
Quillaia extract is a foaming agent, the reason a root beer or a cocktail mixer holds a head. The foaming compounds are saponins — the plant's own soap, which is what the bark was used for before it was a food additive.
