Methylene Bis-Benzotriazolyl Tetramethylbutylphenol

Mid risk

FunctionBroad UV Filter

What it is — Methylene Bis-Benzotriazolyl Tetramethylbutylphenol (INCI of the same name) is a broad-spectrum organic sunscreen filter.

What it does — It absorbs and helps scatter both UVA and UVB light, contributing to a formula's protection against ultraviolet exposure.

Typical use — Found in sunscreens and daytime SPF moisturizers and make-up, usually alongside other UV filters.

Who it suits / good to know — Suits those who want broad-spectrum daytime protection; as a larger-particle filter it is often chosen for its stability. Overall sun protection depends on the finished product's SPF and correct, even application.

Safety — DHALIORA grades it mid risk in its EWG-style, ingredient-by-ingredient review. This reflects the ingredient in general and is not medical advice; patch-test if your skin is easily irritated and follow the finished product's usage directions.
