Ingredient review
Ethylhexyl Bis-Isopentylbenzoxazolylphenyl Melamine
INCI: Ethylhexyl Bis-Isopentylbenzoxazolylphenyl Melamine
A highly effective, photostable sunscreen ingredient that provides broad-spectrum protection without the white cast of mineral filters.
In plain English
This is a synthetic sunscreen ingredient that absorbs both UVA and UVB rays to protect your skin from sun damage. Unlike some mineral sunscreens (like zinc oxide), it doesn't leave a white or chalky residue, so it's popular in cosmetically elegant formulas. It's also very stable in sunlight, meaning it doesn't break down quickly, so your protection lasts longer.

What it is
A synthetic organic compound designed to absorb ultraviolet (UV) light. It belongs to a class of ingredients called triazines and is one of the newer, more advanced UV filters approved for use in many countries.
How it works
It works by absorbing UV radiation and converting it into harmless heat, which is then released from the skin. Because it absorbs both UVA (aging rays) and UVB (burning rays), it provides broad-spectrum protection. Its molecular structure also makes it very photostable, meaning it doesn't degrade quickly in sunlight, so it maintains its protective effect for longer.
Pros
Excellent photostability
Unlike avobenzone, this ingredient doesn't break down quickly in sunlight, meaning your sunscreen stays effective longer without needing frequent reapplication.
No white cast
It's a clear, colorless ingredient, so it won't leave a chalky or white residue on the skin, making it ideal for all skin tones and for use under makeup.
Cons and cautions
Not FDA-approved in the US
While widely used in Europe, Asia, and other regions, this ingredient is not yet approved by the FDA for use in sunscreens sold in the United States, limiting availability.
Synthetic origin
It is a man-made chemical, which may be a turn-off for consumers seeking natural or mineral-only skincare products.
Best for
- Anyone looking for effective, cosmetically elegant sun protection
- People with darker skin tones who want to avoid white cast from mineral sunscreens
Use caution if
- Those with known allergies to organic sunscreen filters
- People who prefer only mineral (physical) sunscreens
