Frequently asked questions

What does Ethylhexyl Triazone protect against?

It absorbs UVB only, so it is paired with UVA filters to deliver broad-spectrum coverage. On its own it is photostable, which helps the overall sunscreen system stay effective over a day of wear.

Is it allowed in US sunscreens?

Not yet. As of this data, its US status is pending, so you will mostly see it in sunscreens formulated for the EU, Japan, and Korea, where it is approved up to 5%.

Is Ethylhexyl Triazone considered safe?

Available data shows an EWG score of 1, no endocrine disruption flag, and no reef toxicity flag, putting it among the better-profile organic UV filters in current use.

Why is it called a new-generation filter?

It belongs to a group of larger, more stable molecules developed after older cinnamates and salicylates, offering strong UVB absorbance with good photostability and a low irritation profile in available data.
