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
No fragrance-linked caution surfaced in the current profile.
This ingredient does not currently read as a fragrance-linked driver in the published evidence and hazard profile.
