Homosalate 7% ●
TL;DR. At 7%, this ingredient functions as an oil-soluble UVB filter in sunscreen and SPF makeup. It helps absorb UVB wavelengths and is usually paired with other filters for broader UVA and UVB coverage.
What does Homosalate 7% do in a cosmetic formula?
At 7%, this ingredient functions as an oil-soluble UVB filter in sunscreen and SPF makeup. It helps absorb UVB wavelengths and is usually paired with other filters for broader UVA and UVB coverage.
Is Homosalate 7% clean?
This ingredient has significant clean-standard friction because of endocrine-screening data, dermal absorption, and changing regional concentration limits. Many clean-beauty frameworks flag or exclude it, especially in leave-on sun-care products.
Is Homosalate 7% sustainable?
This material is synthetic and typically derived from petrochemical feedstocks. It has low water solubility and is not considered readily biodegradable, so wastewater release and environmental persistence are common concerns.
Is Homosalate 7% COSMOS-approved?
It 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 limited biodegradability.
How does Homosalate 7% work chemically?
The molecule is a lipophilic aromatic ester with a UVB-absorbing chromophore, with peak absorption around 306 nm. It is used at several-percent levels where regulations allow, needs oil-phase solubilization, and is commonly combined with UVA filters and photostabilizing systems for broad-spectrum performance.
