Carnauba wax and shellac
Definition
What it is
Wax or insect-derived coating agent: carnauba wax is plant-derived; shellac is derived from the lac bug and is unsuitable for vegans. Neither is a food ingredient; they exist solely to create a glossy surface on candy, pills, and produce.

Explainer
In plain language
Carnauba wax and shellac are glazing agents that add shine and a protective coating to foods and pills. Carnauba wax comes from the leaves of a Brazilian palm tree and is plant-based. Shellac, sometimes called confectioner's glaze or lac resin, is a resin secreted by the lac insect, so it is not suitable for vegans. Neither adds flavor or nutrition; their job is the glossy surface.
Assessment
Why it is flagged
Both are long-established coatings that regulators consider safe at the small amounts used, and the FDA and EFSA authorize them. Clear Label flags them at low severity mainly for transparency, since many people do not realize their shiny candies or apples carry an added coating, and since shellac is animal-derived and matters to vegans. Carnauba wax is also used in cosmetics and car wax, which sometimes surprises people, but food-grade use is at far lower amounts. There is no strong evidence of harm at dietary levels. This is an information flag rather than a safety warning.

Practical
Reading the label
Look for carnauba wax, shellac, confectioner's glaze, lac resin, E903 (carnauba), or E904 (shellac). 'Confectioner's glaze' is the wording most likely to hide shellac's insect origin on candy labels.
Alternatives
If you want to avoid it
Vegans who want to avoid shellac can look for products glazed with carnauba wax or left uncoated, and many candy brands note this on the label. Unwaxed produce is often available and can be rinsed and used the same way.
FAQ
Common questions
Is shellac vegan?
No. Shellac is made from a resin secreted by the lac insect, so it is not considered vegan. Carnauba wax, by contrast, is plant-derived.
Is it safe to eat wax coatings?
Regulators including the FDA and EFSA authorize both carnauba wax and shellac as food glazing agents at the small amounts used, and there is no strong evidence of harm at those levels.
Why is there wax on my apple?
A thin food-grade wax coating helps produce retain moisture and stay shiny during shipping and storage. Some stores sell unwaxed produce if you prefer to skip it.
