Homosalate 9% ●
TL;DR. This ingredient is an oil-soluble UVB filter used in sunscreens and SPF makeup to absorb short-wave UV radiation and help raise the labeled SPF. At 9%, it is being used as a primary sunscreen active rather than a background support ingredient.
What does Homosalate 9% do in a cosmetic formula?
This ingredient is an oil-soluble UVB filter used in sunscreens and SPF makeup to absorb short-wave UV radiation and help raise the labeled SPF. At 9%, it is being used as a primary sunscreen active rather than a background support ingredient.
Is Homosalate 9% clean?
From a clean-beauty perspective, this ingredient has significant standards friction because of regulatory concentration limits, endocrine-screening scrutiny, and frequent restricted-list placement. A 9% level is allowed in some markets, but it exceeds the newer EU cap for many finished products.
Is Homosalate 9% sustainable?
This material is synthetic and typically petrochemical-derived, with limited alignment to renewable sourcing. It is lipophilic and has environmental persistence and aquatic bioaccumulation concerns compared with more readily biodegradable cosmetic ingredients.
Is Homosalate 9% COSMOS-approved?
It is not permitted under COSMOS-natural or COSMOS-organic standards as a sunscreen active. Its synthetic origin, limited biodegradability, and aquatic persistence concerns make it a poor fit with Green Chemistry preferences.
How does Homosalate 9% work chemically?
The molecule is an oil-soluble aromatic ester that absorbs mainly in the UVB range, with peak absorbance around 306 nm, so it is usually paired with UVA filters and film formers for broad-spectrum performance. It is used up to 15% in the United States, while newer EU rules set a lower maximum of 7.34% for eligible face products, making a 9% use level region-sensitive.
