Common Name(s): Butyl methoxydibenzoylmethane,organic uv filter,photostabilising sunscreen active
CAS Number: N/a
DESCRIPTION
What It Does: Absorbs uv radiation at specific wavelengths (uva 320โ400 nm, uvb 290โ320 nm) and dissipates photon energy as heat rather than skin-damaging photochemical reactions.
Why It's Used: Organic uv filters are chosen for their high molar extinction coefficient, specific spectral coverage, and formulation compatibility โ individual filters are combined to provide broad-spectrum coverage across uva+uvb.
How It Works: Uv photon absorption by the aromatic chromophore ฯ-system excites the molecule from sโ ground state to sโ excited state. rapid internal conversion or photoisomerisation dissipates energy as vibrational heat before it can initiate skin photodamage.
Typically Found In: Sunscreens,photoprotective products

Avoid Combining With: No known significant incompatibilities
SCIENTIFIC NOTE
Organic uv filters require photostabilisation (by avobenzone-octocrylene pairing, or triazine stabilisers) as some absorbers degrade on uv exposure โ formulator must verify photostability of the chosen filter combination.
