Octocrylene 9%. Inactive: Water ●
TL;DR. This ingredient is an oil-soluble UV filter used to absorb mainly UVB and short UVA radiation in sunscreen and SPF cosmetics. At 9%, it is present near common regulatory maximums for leave-on sun-care formulas.
What does Octocrylene 9%. Inactive: Water do in a cosmetic formula?
This ingredient is an oil-soluble UV filter used to absorb mainly UVB and short UVA radiation in sunscreen and SPF cosmetics. At 9%, it is present near common regulatory maximums for leave-on sun-care formulas.
Is Octocrylene 9%. Inactive: Water clean?
From a clean-beauty perspective, this ingredient has notable restricted-list friction because it is associated with sensitization reports and can contain or form trace degradation impurities over time. Many stricter standards treat it less favorably than mineral UV filters.
Is Octocrylene 9%. Inactive: Water sustainable?
This material is synthetic and typically petroleum-derived. It is not readily biodegradable and has raised environmental persistence and aquatic-life concerns, which weighs against strong sustainability alignment.
Is Octocrylene 9%. Inactive: Water COSMOS-approved?
It is not permitted for COSMOS-natural or COSMOS-organic certification as a UV filter. Its fossil-derived feedstocks, limited biodegradability, and persistence profile make it a weak fit with Green Chemistry priorities.
How does Octocrylene 9%. Inactive: Water work chemically?
The molecule is a lipophilic aromatic ester with conjugated double-bond chemistry that dissipates absorbed UV energy and can help stabilize certain less photostable filters in the oil phase. It is commonly used up to about 10% depending on jurisdiction, needs antioxidant and packaging support for long-term stability, and is best monitored for impurity formation during shelf life.
