Ingredient guide

What it is and what it does

Bis-Ethylhexyloxyphenol Methoxyphenyl Triazine is the heterocyclic compound that conforms to the formula:

About this ingredient: EU CosIng ingredient registry (via Open Beauty Facts taxonomy) ↗

UV filter: Filters some UV radiation. The ingredient label does not establish a finished product's SPF or UVA protection.
Hair conditioning: Improves cosmetic hair properties such as softness, shine or combability.
Light stabilizer: Helps protect the cosmetic formula against deterioration caused by light. This product-stability role does not establish a finished product's SPF.
Uv absorber: Protects the formulation against UV light. This role is distinct from a skin-protecting UV filter.

Function definitions: European Commission ingredient function definitions (SCCNFP/0299/00, pages 16 to 20) ↗ · BASF: Light stabilization of cosmetic formulas ↗

Registry functions describe possible formulation roles, not results for a finished product. A dictionary entry is not an approval or a safety assessment.

A closer look

What the research shows

Laboratory research

Adding this filter reduced photodegradation of avobenzone and a combination with ethylhexyl methoxycinnamate during simulated irradiation.

What this does not tell us

This measures formulation photostability and optical protection, not clinical prevention of skin aging or cancer.
