Octisalate 3.0% ●
TL;DR. This ingredient is an oil-soluble UVB filter used in sunscreens and SPF products to absorb short-wave UV radiation and support the labeled protection level. It also helps improve the oil-phase spread and compatibility of some sunscreen blends.
What does Octisalate 3.0% do in a cosmetic formula?
This ingredient is an oil-soluble UVB filter used in sunscreens and SPF products to absorb short-wave UV radiation and support the labeled protection level. It also helps improve the oil-phase spread and compatibility of some sunscreen blends.
Is Octisalate 3.0% clean?
From a clean-beauty perspective, it has restricted-list friction because many clean frameworks do not accept synthetic organic UV filters. It is generally low in sensitization reports, but salicylate sensitivity and ongoing regulatory review keep it from being considered unproblematic.
Is Octisalate 3.0% sustainable?
This material is synthetic and typically petrochemical-derived rather than renewable. It is lipophilic, not considered readily biodegradable, and has more environmental persistence concerns than simple plant-derived esters or mineral powders.
Is Octisalate 3.0% COSMOS-approved?
It is not permitted under COSMOS-organic or COSMOS-natural standards, which favor specific mineral UV filters for certified sunscreen claims. Its Green Chemistry fit is weak because it relies on synthetic feedstocks and has limited biodegradability.
How does Octisalate 3.0% work chemically?
The molecule is an oil-soluble aromatic ester with a UV-absorbing ring system and a branched alkyl tail, giving it a peak UVB absorption around 300 to 307 nm. At 3%, it sits within the common 2 to 5% use range and the 5% maximum allowed in several major sunscreen regulations, and it is usually formulated in the oil phase with other filters for broader coverage.
