The panel is not optional on the drug side, and a 59 mL jar has very little panel.

How it happens

The container is chosen for how it looks and feels, artwork is designed, and then somebody establishes that the product is an antiperspirant and needs a Drug Facts panel with prescribed headings and typography.

What has to go on it

The active ingredient and its percentage, the Uses phrase, the four warnings, the direction to apply to underarms only, and the other elements the format requires. That is a lot of text in a fixed structure.

And the percentage is a calculated figure

The declared percentage of the active excludes water, buffer components and propellant, so it is not simply what is on your batch sheet. Getting that arithmetic right is part of the label, not part of the formula.

Small round containers are the hard case

A 59 mL jar or a 65 mL tube, which are exactly the formats this category uses. There is no version of the panel that fits comfortably, which is why the classification question belongs before the container choice.

An aerosol adds two more statements

The keep-away-from-face warning and the pressurized dispenser warning under 21 CFR 369.21. So the format that is hardest to label is also the one that needs the most text.

The cosmetic route avoids all of it

A deodorant that addresses odor and claims only that carries ordinary cosmetic labeling. For a small container that is a genuine design advantage, and for most natural deodorant it is also the accurate classification.

Decide, then choose the container

In that order. The container is the cheapest thing to change at the start and the most expensive to change once tooling, artwork and a case quantity are committed.

Lay the panel out before buying the container

A proof at actual size on the real container, before the case quantity is committed. It takes an afternoon and it is the only way to know whether the format you want can carry the label the product needs.

Written from the federal monograph, not from a formulation bench. Whether a given product is a cosmetic or a drug turns on its ingredients and its claims, and that is a determination with consequences; nothing here substitutes for getting it right for a specific formula and label.
