Homosalate 15.0% ●
TL;DR. This ingredient is an oil-soluble UVB filter used in sunscreens and SPF makeup to absorb short-wave ultraviolet radiation. It mainly supports the UVB portion of a broader filter system rather than providing full broad-spectrum coverage on its own.
What does Homosalate 15.0% do in a cosmetic formula?
This ingredient is an oil-soluble UVB filter used in sunscreens and SPF makeup to absorb short-wave ultraviolet radiation. It mainly supports the UVB portion of a broader filter system rather than providing full broad-spectrum coverage on its own.
Is Homosalate 15.0% clean?
This ingredient has clean-standard friction because of endocrine-activity screening signals and tighter concentration limits in some regions. It can also contribute to eye or skin stinging in sensitive users, especially in high-load sunscreen systems.
Is Homosalate 15.0% sustainable?
This material is synthetically made, typically from petrochemical-derived inputs. Its biodegradability profile is not a strong point, and organic UV filters in rinse-off or beach-use contexts can raise aquatic exposure concerns.
Is Homosalate 15.0% COSMOS-approved?
It is not permitted in COSMOS-natural or COSMOS-organic certified formulas as a synthetic organic UV filter. Its Green Chemistry fit is weak because it relies on conventional synthesis, has limited biodegradability support, and is used at relatively high levels for performance.
How does Homosalate 15.0% work chemically?
The molecule is a lipophilic aromatic ester that absorbs mainly in the UVB range, with peak absorption around 306 nm, and it is commonly used up to 15% in U.S. OTC sunscreen products while lower regional caps apply elsewhere. It is oil-phase soluble, generally paired with other filters for broad-spectrum coverage, and can increase formula oiliness at high levels.
