CPGShield resources · Federal cosmetic labeling
Most cosmetic founders learn one ingredient-labeling rule first:
List the ingredients from highest concentration to lowest.
That is a useful starting point.
It is not the complete rule.
Under FDA's cosmetic ingredient-labeling framework in 21 CFR 701.3, brands can use an important exception for ingredients present at 1% or less.
That means a cosmetic ingredient list does not always have to be one perfectly descending sequence from the first ingredient to the last.
Cosmetic ingredients generally must be declared in descending order of predominance.
If water is the largest component, it typically appears before an ingredient used at 10%.
That 10% ingredient appears before one used at 5%.
Straightforward so far.
But FDA's rules allow a different treatment once you reach certain low-concentration ingredients.
FDA's Cosmetic Labeling Guide describes an option under 21 CFR 701.3(f):
This is why the last portion of an ingredient declaration may not mirror the exact concentration ranking of the formula.
A consumer-or even a founder-can look at the label and assume ingredient number 17 is definitely present at more than ingredient number 18.
That is not always a safe assumption once the declaration reaches the 1%-or-less group.
Imagine a hypothetical face cream containing:
The ingredients above 1% would generally appear in descending order.
But the three ingredients at 1% or less may be declared after that group without maintaining strict concentration order.
So the label could show:
Panthenol, Tocopherol, Xanthan Gum
even though xanthan gum is present at a higher concentration than tocopherol in this hypothetical formula.
The rule does not mean you can randomly reorder the entire ingredient list.
It means the low-concentration portion has more flexibility.
Color cosmetics create additional complexity.
Under FDA's framework, color additives may be declared after the other ingredients without regard to predominance.
For certain color cosmetics sold in multiple shades, FDA also allows special “may contain” or “+/-” style approaches under the applicable regulation.
That makes a lipstick, eyeshadow palette, or foundation range a different labeling problem from a simple single-formula moisturizer.
FDA permits fragrance and flavor compounds to be declared generally as:
rather than requiring every component of the fragrance mixture to be individually named under the ordinary ingredient declaration rule.
That means ingredient review needs to understand regulatory categories, not just compare a formula spreadsheet line-by-line against the package.
Correct order does not fix an incorrect name.
FDA states that cosmetic ingredients must be identified using names established or adopted under the applicable nomenclature rules.
Common problems can include:
The ingredient panel is therefore both a data problem and a formatting problem.
Manual ingredient-list creation looks easy when the formula contains ten ingredients.
It becomes more fragile when a product contains:
Every formulation change can affect the declaration.
And because the 1% rule creates flexibility, a simple “sort descending by percentage” script is not necessarily a complete regulatory solution either.
A serious ingredient review should evaluate:
That final point is important.
A perfectly ordered ingredient list can still contain a substance that creates another compliance problem. An ingredient list can look normal and still hide a compliance problem explains that screening.
Generally yes, but FDA provides exceptions, including for certain ingredients present at 1% or less and for color additives.
Under the FDA framework described in 21 CFR 701.3(f), ingredients other than colors present at 1% or less may be listed after the greater-than-1% ingredients without regard to predominance.
No. It does not allow brands to reorder ingredients present above 1% arbitrarily.
FDA provides specific rules allowing color additives to be listed after other ingredients under the applicable conditions.
No. Ingredient order is only one issue. Ingredient restrictions, hazard matches, state rules, retailer standards, and other requirements may still apply.
This is exactly the kind of detail that is tedious to inspect manually and expensive to discover after packaging is printed.
