What it is
Hexyl diethylamino hydroxybenzoyl benzoate is an oil-soluble organic UV filter that absorbs primarily in the UVA range. It is prized for its strong UVA absorption combined with good photostability, and it is frequently paired with other filters to build balanced broad-spectrum protection. It is an oily liquid that dissolves into the oil phase of emulsions and is common in Japanese and European sunscreens.
Safety & warnings
It is generally considered well tolerated and is regarded as one of the more photostable organic UVA filters, helping it resist breakdown under sunlight. As an oil-phase ingredient it carries the usual low likelihood of contact reactions seen with modern organic filters; sensitive users prone to reactions with sunscreen filters should patch test.
Origin & sourcing
Synthetic; a benzoate-based organic UV absorber manufactured for sun-care use.
History
It was introduced as a photostable UVA filter and became widely adopted in markets where it is approved, often used alongside complementary filters to round out broad-spectrum coverage.
