Ethylhexyl Triazone

TL;DR. This ingredient is an oil-soluble UVB filter used in sunscreens and daytime skin care to boost SPF performance. It is valued in formulation for strong UVB absorbance and high photostability.

What does Ethylhexyl Triazone do in a cosmetic formula?

This ingredient is an oil-soluble UVB filter used in sunscreens and daytime skin care to boost SPF performance. It is valued in formulation for strong UVB absorbance and high photostability.

Is Ethylhexyl Triazone clean?

This ingredient has a generally favorable skin-tolerance profile in regulatory safety reviews, with low sensitization concerns and limited skin penetration. Its clean-beauty friction comes from being a synthetic organic UV filter that many natural-certification and retailer standards do not accept.

Is Ethylhexyl Triazone sustainable?

This material is synthetically produced, typically from petrochemical feedstocks, and it is not considered readily biodegradable. Its high hydrophobicity means it can partition into sediments or organic matter rather than remaining dissolved in water.

Is Ethylhexyl Triazone COSMOS-approved?

This ingredient is not aligned with COSMOS-natural or COSMOS-organic certification because synthetic organic UV filters are not accepted in that framework. From a Green Chemistry lens, it scores well on efficacy at low use levels and photostability, but less well on renewable sourcing and biodegradability.

How does Ethylhexyl Triazone work chemically?

This molecule is a triazine-based, oil-soluble aromatic UV absorber with very strong absorption in the UVB range, roughly centered around 314 nm. In regions where it is permitted, it is commonly used up to about 5% and is usually paired with UVA filters and solubilizers because of its low water solubility.
