Avobenzone 3% ●
TL;DR. This ingredient is an oil-soluble UV filter used primarily for broad UVA coverage in sunscreens, daily moisturizers, and makeup with SPF. At the stated level, it helps absorb long-wave UV before it reaches skin.
What does Avobenzone 3% do in a cosmetic formula?
This ingredient is an oil-soluble UV filter used primarily for broad UVA coverage in sunscreens, daily moisturizers, and makeup with SPF. At the stated level, it helps absorb long-wave UV before it reaches skin.
Is Avobenzone 3% clean?
From a clean-beauty perspective, this ingredient has friction because some standards and retailers restrict synthetic organic UV filters, especially those with photostability and aquatic-environment questions. It can be well tolerated for many users, but formulas usually need stabilizers because the molecule can degrade under sunlight.
Is Avobenzone 3% sustainable?
This material is typically petroleum-derived and synthetically produced, rather than sourced from renewable plant or mineral feedstocks. It is not a strong fit for biodegradability-led standards because environmental fate data raise persistence and aquatic-exposure questions.
Is Avobenzone 3% COSMOS-approved?
It is not permitted in COSMOS-natural or COSMOS-organic products as a sunscreen active. Its fit with Green Chemistry is weak because it relies on synthetic petrochemical feedstocks and needs photostabilizing co-formulation rather than simple, readily biodegradable design.
How does Avobenzone 3% work chemically?
The molecule is a lipophilic beta-diketone UVA absorber that shifts between keto and enol forms, with the enol form responsible for strong absorption across roughly 320 to 400 nm. In the U.S., 3% is the OTC maximum use level, while some other regions allow higher levels, and formulators commonly pair it with photostabilizers and compatible oil phases to limit light-driven breakdown.
