The ingredient list
On this page10
The basic rule
Each ingredient, by name, in descending order of predominance. For a beard oil that is the carrier oils first, largest to smallest, and the fragrance or essential oils after them.
The grouping alternative
Ingredients other than color additives present above 1 percent in descending order; then ingredients at not more than 1 percent without respect to order; then color additives without respect to order. This is an allowance in the regulation, not a shortcut.
Why that matters at this scale
It means the handful of things dosed at a fraction of a percent, which are exactly the ones whose relative order you are least certain of, do not have to be ranked against each other.
Fragrance and flavor
May be declared as "fragrance" and "flavor" rather than broken out into their components. That is how a proprietary scent blend is handled, and it is in the regulation rather than being an industry habit.
Allergens are a separate question
MoCRA requires FDA to issue regulations on fragrance allergen labeling. Those rules were not final when this page was written, so this is a part of the label worth re-checking rather than setting and forgetting.
Prominence is part of the requirement
The declaration has to be likely to be read and understood by ordinary individuals under normal conditions of purchase. Five point type wrapped around the back of a 30 mL bottle is a compliance question, not just a design one.
Common or usual names
FDA tells small makers to use common or usual names without additional description. The place to be creative is the front panel.
Order is a statement about the formula
Descending order of predominance means the list discloses your formula in outline to anybody who reads it, which is true of every cosmetic on every shelf and is not a reason to get the order wrong. The 1 percent rule is the only latitude the regulation gives, and it is latitude about ordering rather than about disclosure.
Write it once, for the range
Four products sharing a scent share part of an ingredient list. Building those lists together, from the same batch sheet, is how they stay consistent, and inconsistency between two of your own labels is the kind of thing a careful customer notices and a regulator reads as sloppiness.
