Is it a concern?
Minor concern: no hazard classifications on record. It is listed for cosmetic use in the EU.

What the listings say

Permitted, with conditions — Butyl methoxydibenzoylmethane appears on published "allowed" regulatory lists rather than on a restriction list.

1-(4-tert-Butylphenyl)-3-(4-methoxyphenyl) propane-1,3-dione / Avobenzone is listed in Annex VI of the EU Cosmetics Regulation (EC) 1223/2009 (UV filters allowed in cosmetic products).

The score describes this ingredient's chemical identity — its hazard profile from published classifications and regulatory status — not the safety of any product it appears in.

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.

Good fit

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.

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.
