Ingredient guide

What it is and what it does

1-[4--1‚1-Dimethylethyl-phenyl]-3--4-methoxyphenyl-propane-1‚3-dione

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.
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) ↗

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

Human research on a combination

Avobenzone plus padimate O protected against experimentally induced UVA effects better than a comparator containing padimate O, oxybenzone and octyl salicylate.

What this does not tell us

Subjects were photosensitized with oral methoxsalen; the reported result is a filter combination, not an isolated avobenzone effect or routine-use outcome.
