Shellac (E904) is one of the markers Open Food Facts uses to classify a food as ultra-processed (NOVA group 4).

What it is and why it counts

Shellac is a resin secreted by lac insects, used as a glazing agent on sweets, coated chocolates and fruit.

Cosmetic additives

NOVA calls these additives "cosmetic": they change how a product looks, feels or tastes rather than keeping it safe to eat. Their presence is one of the two defining signs of an ultra-processed food.
