Benzophenone-1 ●
TL;DR. This ingredient is primarily used as a UV absorber and light stabilizer, helping protect formulas, colors, and fragrances from sunlight-driven degradation.
What does Benzophenone-1 do in a cosmetic formula?
This ingredient is primarily used as a UV absorber and light stabilizer, helping protect formulas, colors, and fragrances from sunlight-driven degradation.
Is Benzophenone-1 clean?
From a clean-beauty perspective, it carries significant restricted-list friction because of endocrine-activity screening signals and sensitization concerns. It is more commonly treated as a flagged synthetic UV absorber than as a low-concern support ingredient.
Is Benzophenone-1 sustainable?
This material is typically made from petrochemical feedstocks and is not a strong fit for renewable-sourcing goals. It is associated with environmental persistence and aquatic-organism concern, which weakens its sustainability profile.
Is Benzophenone-1 COSMOS-approved?
It is not permitted under COSMOS natural or organic standards as a conventional synthetic UV absorber. Its petrochemical sourcing, limited biodegradability profile, and persistence concerns place it outside a strong Green Chemistry alignment.
How does Benzophenone-1 work chemically?
The molecule is an aromatic ketone with two phenolic hydroxyl groups, which lets it absorb ultraviolet light and dissipate that energy before it degrades the surrounding formula. It is poorly water-soluble, more compatible with alcohol or oil-phase systems, and is typically used at low formula-protection levels where allowed.
