What this ingredient generally does

Not reviewed yet

No reviewed note yet.

SPF Scout publishes a plain-language note on what an ingredient generally does only after a person has reviewed it. This one has not been reviewed yet, so this page shows only the recorded label facts: the INCI name, the CAS number, the function on record, and the published formulations that list it.

Published formulations that list this ingredient

These are the formulations currently published in the SPF Scout catalog whose stored ingredient declaration includes this ingredient. It is not a list of every product on the market, and the order carries no meaning.

Checking this against your own list

You can select this ingredient in the SPF Scout app as one to flag. The app compares your selections against a product's stored declaration on your device; your list never reaches this website.

This comparison does not predict whether your skin will react.

Where this information comes from

Ingredient names, CAS numbers and recorded functions come from SPF Scout’s curated ingredient dictionary, grounded in CosIng, the European Commission’s Cosmetic Ingredient Database. Content © European Union, reused with acknowledgement.
