Homosalate 7.0% ●
TL;DR. This ingredient is an oil-soluble organic UVB filter used in sunscreens and SPF moisturizers to absorb short-wave UV radiation and contribute to SPF. It is often paired with other filters because its coverage is narrow and its absorbance is modest on its own.
What does Homosalate 7.0% do in a cosmetic formula?
This ingredient is an oil-soluble organic UVB filter used in sunscreens and SPF moisturizers to absorb short-wave UV radiation and contribute to SPF. It is often paired with other filters because its coverage is narrow and its absorbance is modest on its own.
Is Homosalate 7.0% clean?
From a clean-beauty perspective, this ingredient is heavily scrutinized because of endocrine-screening signals and changing regulatory concentration limits. Many stricter retailer standards restrict it or do not accept it, especially in formulas positioned around mineral-only sun protection.
Is Homosalate 7.0% sustainable?
This material is synthetic and petrochemical-derived, with limited biodegradability compared with many bio-based cosmetic ingredients. It has been detected in aquatic environments, which gives it a weaker sustainability profile than readily biodegradable alternatives.
Is Homosalate 7.0% COSMOS-approved?
It is not permitted under COSMOS organic or natural standards as a synthetic organic sunscreen filter. Its Green Chemistry fit is limited by petrochemical sourcing, low biodegradability, and environmental persistence concerns.
How does Homosalate 7.0% work chemically?
The molecule is a lipophilic aromatic ester that absorbs mainly in the UVB range, so formulators use it in the oil phase and combine it with broader UVA and UVB filters for balanced protection. Regulatory maximums vary by market, with use up to 15% in U.S. OTC sunscreens and lower, product-type-specific limits in the EU around 7.34%.
