Octocrylene 9.0%. Inactive: Water ●
TL;DR. This ingredient is an oil-soluble organic UV filter used here at 9% to raise SPF, mainly through UVB and short-UVA absorption. It also helps photostabilize other sunscreen filters in the oil phase.
What does Octocrylene 9.0%. Inactive: Water do in a cosmetic formula?
This ingredient is an oil-soluble organic UV filter used here at 9% to raise SPF, mainly through UVB and short-UVA absorption. It also helps photostabilize other sunscreen filters in the oil phase.
Is Octocrylene 9.0%. Inactive: Water clean?
From a clean-beauty perspective, this ingredient is commonly restricted or excluded because of sensitization and photoallergy reports, plus concern around benzophenone impurity or degradation over time. It is a regulated sunscreen active, but it carries more clean-standard friction than mineral filters.
Is Octocrylene 9.0%. Inactive: Water sustainable?
This material is synthetically made, typically from petrochemical feedstocks, and is not considered readily biodegradable. It has been detected in aquatic environments and wildlife, so its persistence and bioaccumulation profile are key sustainability concerns.
Is Octocrylene 9.0%. Inactive: Water COSMOS-approved?
This ingredient is not permitted under COSMOS-natural or COSMOS-organic sunscreen standards. Its Green Chemistry fit is limited because it is synthetic, non-renewable in typical supply chains, and has poor biodegradation characteristics.
How does Octocrylene 9.0%. Inactive: Water work chemically?
The molecule is a lipophilic ester with a conjugated cyanoacrylate chromophore that absorbs UV energy and dissipates it as heat, with strong usefulness in the UVB range. In the U.S. it is allowed up to 10% in OTC sunscreens, and the 9% level shown here is near that ceiling, with formulation stability depending on oil-phase solubility, antioxidant support, packaging, and control of benzophenone formation during storage.
