The label
On this page9
What has to be on it
The California ingredient disclosure with its toll-free number and website address, the manufacture date or a code for it, the net contents, and whatever directions and cautions the product needs.
Plus a space for the variable mark
Which is the part people forget. A clear, flat area that a coder, a stamp or a sticker can reach, designed in rather than found afterwards.
The sprayer eats the bottle
A fine mist pump with an overcap occupies a real fraction of the height, and the label cannot run under the shoulder. The usable panel is smaller than the bottle suggests.
Which argues for a back label
Front for the brand and the scent name, back for the disclosure, the directions and the date area. On a clear bottle a back label is read through the liquid, which is legible if the type is sized for it.
Alcohol runs down the outside
Every time it is used. The adhesive and the face stock have to survive that, which is the same lesson the grooming and spirits properties reach from different directions.
Scent name is not a claim
Calling something Fresh Linen is fine. Saying it eliminates bacteria is not, and the two sit three inches apart on the same label, which is how the second one gets added.
Proof it on the filled bottle
With the sprayer fitted, the liquid in and the date code applied. The flat artwork cannot show you what the curve hides or what the liquid does to the back label.
A clear bottle means the back label is read through the liquid
Which changes the type size you need and the colour that works. Tinted or coloured product shifts it again, so proof it with the actual liquid rather than against white.
