Homosalate 10%

TL;DR. This ingredient is an oil-soluble UVB filter used in sunscreens and SPF cosmetics to absorb short-wave UV radiation and raise SPF. It is usually paired with UVA filters because it does not provide broad-spectrum coverage on its own.

What does Homosalate 10% do in a cosmetic formula?

This ingredient is an oil-soluble UVB filter used in sunscreens and SPF cosmetics to absorb short-wave UV radiation and raise SPF. It is usually paired with UVA filters because it does not provide broad-spectrum coverage on its own.

Is Homosalate 10% clean?

From a clean-beauty lens, this ingredient has significant restricted-list friction because of endocrine-activity screening signals and changing concentration limits in major markets. Skin irritation is not the main concern, regulatory uncertainty and high-exposure use are.

Is Homosalate 10% sustainable?

This material is synthetic and generally petrochemical-derived, not a renewable or minimally processed input. It is flagged for aquatic persistence and bioaccumulation potential, so its environmental profile is weaker than readily biodegradable cosmetic ingredients.

Is Homosalate 10% COSMOS-approved?

It is not permitted under COSMOS-natural or COSMOS-organic standards as a synthetic organic UV filter. Its Green Chemistry alignment is limited because it relies on synthetic feedstocks and has persistence concerns rather than ready biodegradability.

How does Homosalate 10% work chemically?

The molecule is an oil-soluble aromatic ester that mainly absorbs UVB energy in the roughly 295 to 315 nm range. A 10% level is within the current U.S. OTC sunscreen limit of 15%, but it exceeds the current EU limit of 7.34% for permitted face products, and it is typically combined with UVA filters for balanced protection.
