HOMOSALATE 4.0% ●
TL;DR. This ingredient is an oil-soluble UVB filter used in sunscreens and SPF cosmetics to absorb UV radiation and help raise labeled sun-protection performance.
What does HOMOSALATE 4.0% do in a cosmetic formula?
This ingredient is an oil-soluble UVB filter used in sunscreens and SPF cosmetics to absorb UV radiation and help raise labeled sun-protection performance.
Is HOMOSALATE 4.0% clean?
It has notable clean-standard friction because regulators have reviewed endocrine-activity signals and set concentration limits in some markets. It is not typically treated as a low-concern mineral-style sunscreen filter.
Is HOMOSALATE 4.0% sustainable?
This material is synthetic and generally petroleum-derived. It is not a strong biodegradability fit and has aquatic-environment scrutiny, so its sustainability profile is weaker than readily biodegradable bio-based ingredients.
Is HOMOSALATE 4.0% COSMOS-approved?
It is not permitted under COSMOS natural or organic standards for certified products. Its synthetic petrochemical route and persistence concerns make it a weak fit with Green Chemistry preferences for renewable feedstocks, ready biodegradation, and lower ecological burden.
How does HOMOSALATE 4.0% work chemically?
The molecule is an oil-soluble aromatic ester UVB filter that absorbs mainly in the roughly 295 to 315 nm range and is usually paired with other filters for broader-spectrum coverage. Formulators use it within local regulatory caps, with this 4.0% level below the U.S. OTC maximum of 15% and below the EU reduced maximum of 7.34%.
