Suitability
Context-specific fit derived from published classifications and the current ingredient evidence profile.
Food use
Food-use source coverage is present in the current record.
The ingredient appears in food-oriented source coverage or allowed-use references, which makes food use easier to support than a context with no domain signal at all.
Fragrance avoidance
Not a strong fit for fragrance avoidance because it carries Fragrance.
The ingredient itself is a fragrance-linked signal, so it is better treated as an avoid case when fragrance exposure is the main concern.
Where it has been recorded
