A modern broad-spectrum chemical UV filter that absorbs across UVA and UVB and helps stabilize other filters.
A modern, photostable chemical UV filter providing strong UVA protection in broad-spectrum systems.
An oil-soluble synthetic UVB filter (3V Sigma Uvasorb HEB), EU-approved at a maximum concentration of 10%, highly photostable with very low dermal absorption and a strong safety profile.
A broad-spectrum silicone-modified benzotriazole UV filter (Meroxyl XL) that absorbs both UVA and UVB radiation; photostable and well-tolerated, used outside the US at up to 15%.
A common chemical UVB filter (octinoxate) permitted up to 10% in EU and 7.5% in US sunscreens, with confirmed endocrine activity at high doses per 2025 SCCS opinion.
A UVA-absorbing photostabilizer (Hallstar SolaStay S1) that prevents degradation of avobenzone and other UV filters via singlet-state quenching; listed in EU CosIng (ref 87035) as a photostabilizer but not as an Annex VI approved UV filter.
A modern, highly photostable chemical UV filter offering strong UVB protection in broad-spectrum sunscreens.

A polymeric UV filter where benzalmalonate UVB-absorbing chromophores are covalently attached to a polydimethylsiloxane backbone. High molecular weight prevents significant skin penetration. Approved in EU and Japan. Used in Anessa Perfect UV.
A water-soluble, photostable organic UVA filter (Ecamsule/Mexoryl SX) approved in the EU at up to 10% that absorbs UV radiation predominantly in the UVA range.
A mineral UV filter effective against UVB and short UVA.
An insoluble organic UV filter with broad-spectrum UVA+UVB protection. Photostable — does not degrade on UV exposure. Used in Japanese and European sunscreens. Related to Tinosorb S. Not yet FDA-approved for US market.
