Suitability

Context-specific fit derived from published classifications and the current ingredient evidence profile.

Food use

Nothing to weigh for this context yet.

No signal in this context

We have no published hazard signal for this ingredient, so we cannot say how it behaves in this context — that is missing evidence, not a clean result.

Fragrance avoidance

Not a strong fit for fragrance avoidance because it carries Fragrance.

Avoid

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
