Methoxydibenzoylmethane ●
TL;DR. This ingredient functions primarily as an oil-soluble UVA filter in sunscreens and daytime skin-care products. It helps extend protection into the longer UVA range, where many UVB-focused filters do less.
What does Methoxydibenzoylmethane do in a cosmetic formula?
This ingredient functions primarily as an oil-soluble UVA filter in sunscreens and daytime skin-care products. It helps extend protection into the longer UVA range, where many UVB-focused filters do less.
Is Methoxydibenzoylmethane clean?
From a clean-beauty perspective, this ingredient has friction because it is a synthetic sunscreen active with regulatory concentration limits and known photostability challenges. It is generally considered usable when properly formulated, but it is not a low-controversy choice across stricter clean standards.
Is Methoxydibenzoylmethane sustainable?
This material is typically petrochemical-derived and is not a strong fit for renewable-sourcing goals. Environmental data are less favorable than for readily biodegradable plant-based ingredients, and sunscreen filters in general receive scrutiny for aquatic persistence and exposure.
Is Methoxydibenzoylmethane COSMOS-approved?
This ingredient is not permitted in COSMOS-natural or COSMOS-organic formulas as a conventional synthetic UV filter. Its Green Chemistry profile is limited by nonrenewable feedstocks, specialized synthesis, and weaker biodegradability alignment.
How does Methoxydibenzoylmethane work chemically?
The molecule is an oil-soluble aromatic beta-diketone that absorbs mainly in the long-UVA range, with peak absorbance around 357 nm. It is photolabile unless stabilized with compatible filters and antioxidants, and sunscreen regulations commonly cap use around 3 percent in the U.S. and up to 5 percent in the EU.
