Homosalate ●
TL;DR. This ingredient is an oil-soluble UVB filter used as a sunscreen active to raise SPF and absorb rays mainly in the UVB range.
What does Homosalate do in a cosmetic formula?
This ingredient is an oil-soluble UVB filter used as a sunscreen active to raise SPF and absorb rays mainly in the UVB range.
Is Homosalate clean?
From a clean beauty perspective, this ingredient has significant friction because of endocrine-activity questions, skin-sensitization potential in some users, and tightening regulatory limits. It is commonly flagged or excluded by stricter retailer and brand standards.
Is Homosalate sustainable?
This material is typically synthetic and petrochemical-derived. It is not considered readily biodegradable and raises aquatic-exposure concerns because sunscreen filters can enter waterways during use.
Is Homosalate COSMOS-approved?
This ingredient is not permitted under COSMOS-natural or COSMOS-organic standards. Its fit with Green Chemistry is weak because it relies on nonrenewable feedstocks and has persistence concerns rather than a strong biodegradability profile.
How does Homosalate work chemically?
The molecule is an oil-soluble aromatic ester that absorbs UVB light, with peak absorption commonly cited around 306 nm. It is used under regional sunscreen-active limits, historically up to 15% in the U.S., and is usually combined with other filters because it does not provide broad UVA coverage on its own.
