Nail

Two rules, and the container decides both

By Dwight Davis, Founder

Updated

On this page6
Methacrylic acid over 5 percent needs child-resistant packaging unless it is in a pen-like applicator with no free liquid inside, which is an exemption written as a description of a package. And a glue remover is caught at 500 mg of acetonitrile per container, which is a mass rather than a concentration, so the bottle size is the trigger.

Getting started

Before the first fill.
Is this for you at allFrom formula to bottle
