Makeup Labels: Why Colors Are Listed Differently and What “May Contain” Means

The usual rule, and the exception

Under US rules (21 CFR 701.3), ingredients above 1% are declared in descending order of weight. The list is a ranking, not a measurement: it says which ingredient outweighs which, never by how much. At 1% or less, ingredients may be listed in any order.

Color additives are exempt from that rule. They may be listed at the end regardless of how much is present.

What “may contain” means

Products sold in shade ranges commonly declare every colorant used across the whole range, prefixed “may contain”. The list you are reading may not describe the item in your hand. This is normal and legal, and it means the position-in-the-list question cannot be applied to colorants in a shade-range product at all.

Certified and exempt colors

Certified colors, mostly synthetic FD&C and D&C dyes, are batch-tested by the FDA before each batch is sold. Exempt colors, typically mineral-derived pigments such as iron oxides, titanium dioxide or mica, are approved by regulation but are not batch-tested. Both are exempt from the ordering rule.

A color can be approved for one use and not another

A color additive’s approval is scoped to specific uses, and the scope is not printed on the pack. D&C Red No. 27, for example, is approved “for coloring cosmetics generally”, but its listing does not extend to the eye area. Under the FDA’s general rule it can sit in a lipstick or a blush, and it cannot legally sit in a mascara or an eyeshadow.

“Cruelty-free”

According to the FDA’s own published position, there is no legal definition of the term and its use is unrestricted. A third-party certification audits against a defined standard. The bare word on a pack, without a certifying logo, commits a manufacturer to nothing in particular.

When you compare prices

Compare per gram for solids and per milliliter for liquids, and never mix the two. Pick one precise product type, such as one shade of matte liquid lipstick, list ten widely available options, and take the median.

Materials behind these labels

• D&C Red No. 27 — A certified colorant, and the clearest example of approval scoped to specific uses.
• Iron Oxides — Mineral-derived exempt colors, approved by regulation but not batch-tested.
• Titanium Dioxide — A white colorant and opacifier used for coverage.
