Butyl Methoxydibenzoylmethane ●
TL;DR. This ingredient is an oil-soluble UV filter used to provide broad UVA protection in sunscreens, moisturizers, and makeup with SPF. It helps reduce UVA-driven photoaging support claims when paired with a complete UV-filter system.
What does Butyl Methoxydibenzoylmethane do in a cosmetic formula?
This ingredient is an oil-soluble UV filter used to provide broad UVA protection in sunscreens, moisturizers, and makeup with SPF. It helps reduce UVA-driven photoaging support claims when paired with a complete UV-filter system.
Is Butyl Methoxydibenzoylmethane clean?
From a clean-beauty perspective, this ingredient has notable standard friction because it is synthetic and is restricted or excluded by several clean-retailer lists. It is generally well studied for regulated sunscreen use, but it can be sensitizing for a small subset of users and needs stabilization in formulas.
Is Butyl Methoxydibenzoylmethane sustainable?
This material is typically petrochemical-derived and is not a strong fit for renewable-sourcing goals. It has biodegradability and aquatic-persistence concerns compared with simpler, readily biodegradable cosmetic ingredients.
Is Butyl Methoxydibenzoylmethane COSMOS-approved?
It is not permitted under COSMOS-natural or COSMOS-organic standards as a conventional synthetic UV filter. Its fit with Green Chemistry is limited by petrochemical sourcing, photostability challenges, and weaker biodegradability profile.
How does Butyl Methoxydibenzoylmethane work chemically?
The molecule is oil soluble, highly conjugated, and absorbs mainly in the UVA range, with peak absorbance near 357 nm. Regulatory maximums vary by market, commonly up to 3% in the United States and up to 5% in the European Union, and formulas typically pair it with photostabilizers because it can degrade under UV exposure.
