Methylene Bis-Benzotriazolyl Tetramethylbutylphenol ●
TL;DR. This ingredient is a broad-spectrum UV filter used in sunscreens and daytime skin care to absorb and scatter UVA and UVB radiation. It is especially valued for photostability and coverage across the UVA range.
What does Methylene Bis-Benzotriazolyl Tetramethylbutylphenol do in a cosmetic formula?
This ingredient is a broad-spectrum UV filter used in sunscreens and daytime skin care to absorb and scatter UVA and UVB radiation. It is especially valued for photostability and coverage across the UVA range.
Is Methylene Bis-Benzotriazolyl Tetramethylbutylphenol clean?
From a clean-beauty perspective, it has a favorable skin profile because the particles are large, highly insoluble, and show low skin penetration in standard assessments. The friction point is that it is a synthetic UV filter and may be treated cautiously by standards that limit petrochemical synthetics or nano-scale sunscreen materials.
Is Methylene Bis-Benzotriazolyl Tetramethylbutylphenol sustainable?
This material is synthetically made and is not readily biodegradable. Because it is highly insoluble and particle-based, it is expected to partition into solids such as wastewater sludge or sediment rather than dissolve freely in water.
Is Methylene Bis-Benzotriazolyl Tetramethylbutylphenol COSMOS-approved?
It is not permitted under COSMOS-natural or COSMOS-organic standards, which are much narrower for sunscreen actives and generally center on selected mineral filters under defined conditions. Its Green Chemistry alignment is limited by petrochemical-style synthesis, persistence, and low biodegradability, despite good photostability and low dermal absorption.
How does Methylene Bis-Benzotriazolyl Tetramethylbutylphenol work chemically?
The molecule is a large, highly lipophilic bis-benzotriazole phenolic UV absorber used as a micronized dispersion rather than a dissolved oil-phase filter. In the EU it is authorized up to 10% in sunscreen products, including nano form under labeling and particle-specification conditions, and it is commonly paired with other filters to broaden SPF and UVA protection.
