Ingredient review
Bis-Ethylhexyloxyphenol Methoxyphenyl Triazine
INCI: BIS-ETHYLHEXYLOXYPHENOL METHOXYPHENYL TRIAZINE
A gold-standard sunscreen ingredient that offers broad-spectrum protection without the white cast of older mineral filters.
In plain English
This is a synthetic sunscreen ingredient that works like a sponge to absorb and scatter both UVA (aging) and UVB (burning) rays. It's known for being very stable in sunlight, meaning it doesn't break down quickly, so your protection lasts longer. Unlike some mineral sunscreens, it doesn't leave a chalky white residue on the skin.

What it is
A synthetic organic compound designed specifically as a broad-spectrum UV filter. It is a derivative of triazine and is often used in combination with other sunscreens to boost overall protection.
How it works
It absorbs UV radiation and converts it into harmless heat, preventing the energy from damaging skin cells. Its molecular structure is very stable, so it resists degradation from sunlight, maintaining its protective effect for longer periods.
Pros
Excellent photostability
Unlike some chemical filters like avobenzone, this ingredient doesn't degrade quickly in sunlight, so your sunscreen stays effective longer without needing frequent reapplication.
No white cast
It is a clear, colorless ingredient that blends invisibly into all skin tones, making it a favorite for daily wear and for people with melanin-rich skin.
Cons and cautions
Synthetic origin
It is a lab-created compound, which may not appeal to consumers seeking exclusively natural or mineral-based skincare products.
Often used in combination
While powerful, it is rarely the sole UV filter in a product. It works best when paired with other filters to achieve very high SPF or broad-spectrum ratings, which can complicate the ingredient list.
Best for
- Anyone looking for reliable, broad-spectrum sun protection
- People with darker skin tones who dislike the white cast from mineral sunscreens
Use caution if
- Individuals with a known allergy to triazine compounds (very rare)
