Homosalate 5.0% ●
TL;DR. This ingredient is an oil-soluble UV filter used primarily to absorb UVB radiation and help build SPF in sunscreen and SPF cosmetics.
What does Homosalate 5.0% do in a cosmetic formula?
This ingredient is an oil-soluble UV filter used primarily to absorb UVB radiation and help build SPF in sunscreen and SPF cosmetics.
Is Homosalate 5.0% clean?
From a clean-beauty perspective, it has meaningful friction because several standards flag it for endocrine-activity questions and regulatory concentration limits. It is used in conventional SPF systems, but many stricter clean programs restrict or exclude it.
Is Homosalate 5.0% sustainable?
This material is a petrochemical-derived synthetic molecule and is not considered readily biodegradable. Monitoring studies have reported it in aquatic environments, so persistence and bioaccumulation potential are the main sustainability concerns.
Is Homosalate 5.0% COSMOS-approved?
It is not permitted under COSMOS-natural or COSMOS-organic standards. Its synthetic origin, limited biodegradability, and aquatic persistence concerns make it a poor fit with Green Chemistry preferences for renewable inputs and readily biodegradable materials.
How does Homosalate 5.0% work chemically?
The molecule is an aromatic ester that absorbs mainly in the UVB range, with peak absorption around 306 nm, and it is typically used in the low to mid single digits, with higher regional caps depending on regulation. It is oil-soluble, generally photostable enough for sunscreen use, and is commonly paired with other filters to broaden UVA and UVB coverage.
