Child resistant closures

When a closure must be child resistant

By Dwight Davis, Founder

On this page9
The thresholds are specific and low enough that a real formula reaches them.

Methyl alcohol

Liquid containing 4 percent or more by weight of methyl alcohol. Four percent is not much, and methanol turns up in shellac thinners and in denatured alcohol blends.

Turpentine

Liquid containing 10 percent or more by weight of turpentine. Relevant to traditional varnishes and to wax finishes thinned the old way.

Ethylene glycol

Liquid containing 10 percent or more by weight of ethylene glycol.

The solvent entry

Liquid solvents containing 10 percent or more by weight of benzene, toluene, xylene, petroleum distillates or combinations of them, where the viscosity is under 100 Saybolt universal seconds at 100F. Two conditions, and both have to be met.

The low-viscosity hydrocarbon entries

Nonemulsion liquids containing 10 percent or more hydrocarbons by weight under the same viscosity test. Spray devices are excluded, and so are products in which the liquid cannot flow freely, paint markers being the example given.

Glue removers

A remover containing more than 500 mg of acetonitrile in a single container. Note that this one is a quantity per container rather than a concentration, so the package size is part of the test.

Which is the point worth carrying away

One of these entries depends on how much is in the container rather than what is in it. Offering the same formula in a larger size can create an obligation that the smaller size did not have.

Read the formula, not the category

There is no entry for "wood glue" or for "varnish". The determination is made against what is actually in the product at what weight percentage, which means two products on the same shelf can land differently.

16 CFR 1700.14(a), the household substances requiring special packaging. Those bearing on this craft include methyl alcohol at 4 percent or more by weight, turpentine at 10 percent or more, ethylene glycol at 10 percent or more, liquid solvents at 10 percent or more benzene, toluene, xylene or petroleum distillates with a viscosity under 100 Saybolt universal seconds at 100F, nonemulsion liquids at 10 percent or more hydrocarbons under the same viscosity test, and glue removers containing more than 500 mg of acetonitrile in a single container. law.cornell.edu
Written from 16 CFR 1500.14(b)(8), 1500.121 and 1700.14, and from the catalog as it stood on 17 October 2026. Whether a particular product is an art material, what its chronic hazard labeling should say, and whether its closure must be child resistant are determinations about a specific formula; the first of those is a question for a toxicologist by regulation, and nothing here substitutes for one.
