Suitability

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

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.
