What does Homosalate 10.0% do in a cosmetic formula?
This ingredient is a synthetic organic UV filter used mainly for UVB coverage in sunscreens, moisturizers, and makeup with SPF.
Is Homosalate 10.0% clean?
From a clean-beauty perspective, it has significant friction because it has been reviewed for endocrine activity and is subject to tighter concentration limits in some regions. At 10%, it is within the U.S. OTC sunscreen limit, but it is above the newer EU cap for face products and is not broadly accepted by stricter clean standards.
Is Homosalate 10.0% sustainable?
This material is generally synthesized from petrochemical-derived feedstocks and is oil-soluble rather than water-soluble. It is not considered readily biodegradable, and aquatic persistence plus bioaccumulation concerns are the main environmental issues.
Is Homosalate 10.0% COSMOS-approved?
It is not permitted under COSMOS-natural or COSMOS-organic standards as a synthetic UV filter. Its Green Chemistry alignment is weak because it relies on nonrenewable feedstocks and has limited biodegradability.
How does Homosalate 10.0% work chemically?
The molecule is a small, oil-soluble aromatic ester that absorbs primarily in the UVB range, with peak absorbance around the low 300 nm region. It is typically used around 5% to 15% where allowed, needs oil-phase solubilization, and is usually paired with other filters for broader, more stable SPF coverage.
