The Claim
Computational simulations predict that avobenzone in its enol form absorbs UVA radiation maximally at 360–361 nm in polar solvents, while its keto form absorbs in the UVB range at 285 nm, with solvent polarity significantly shifting absorption peaks due to increased dipole moments and electronic stabilization.
What the research says
Not yet evaluated
We are still looking at what the research says.
These are independent scores, not a percentage. Higher-grade studies count more, so a single strong opposing study can outweigh several weaker ones.
Avobenzone in its enol form absorbs UVA light most strongly at 360–361 nm in polar solvents, and in its keto form it absorbs UVB light at 285 nm; the polarity of the solvent shifts these absorption peaks by altering the molecule's dipole moment and electronic stability.

In water or alcohol, avobenzone changes shape to a form that catches UVA light best at 360–361 nm, while in other environments it shifts to a different shape that catches UVB light at 285 nm. The presence of water or alcohol makes the UVA-catching shape more stable and more efficient at absorbing that specific wavelength.
What the research says
1 studyComputer models in this study show that avobenzone works better in two different forms: one blocks UVA rays (around 360 nm) and the other blocks UVB rays (around 285 nm), and water or alcohol makes the UVA-blocking form even better at absorbing light—just like the claim says.
