What size
Updated
On this page6
A short page with an unusual consequence attached, because in this category the container size can change what the label is allowed to be.
The standard sizes
The category runs small. A conventional twist tube holds a small fraction of an ounce, and the common sizes cluster tightly around that.
Pots and tins offer more range, from a sample size up to something that is really a salve.
Standardizing on one or two is the right call: caps, shrink bands, labels, trays and cartons all key to the size, and a second size doubles every one of those lines.
Net quantity is a weight
The declaration is a net weight, and the tube is specified by volume. The two meet only through the density of your formula, which changes with the wax and butter you chose.
So establish the fill by filling and weighing, across a batch, and declare what you can consistently hold. Do not take the number off the supplier's specification for the tube.
What the size decides
How much label there is, which is the binding constraint on a product this small.
Perceived value, and the price point. The category has strong price anchors and a larger tube does not command a proportionally larger price.
And how quickly a customer finishes it, which sets how often they come back and how long the oils have to survive.
The drug-side constraint
If the product is a lip protectant drug, the Drug Facts panel may use the modified small-package format only where it would otherwise need more than 60 percent of the total surface area available to bear labeling.
That makes the size a compliance variable. Work out the panel, measure the label the tube actually gives you, and let those decide the size, rather than choosing the tube and discovering the panel will not fit.
