Toy and child-safe finishes

Overview

This entry covers what the US rules say about finishes on toys and children's furniture, and what to do about it in a small workshop. Three federal texts matter: 16 CFR 1303 bans lead-containing paint and similar surface coatings on toys and other articles for children and on furniture; 16 CFR 1500.91 sets out when a material is determined not to exceed the lead limits without testing; and 16 CFR 1250 makes the ASTM F963 toy standard mandatory for toys. This is a regulatory summary for a woodworker, not legal advice. If you sell toys, you are a manufacturer and the Consumer Product Safety Commission's testing and certification rules apply; I could not open the CPSC pages, so those requirements are not described here and you should read them directly.

Pros

• Untreated or unadulterated wood is the one case 16 CFR 1500.91 treats as not exceeding the lead limits without testing, so leaving a toy bare, or only oiled with a single-ingredient oil, is the simplest route.
• Finishes with a published ingredient list and a stated cure time make the question answerable.
• Oils and waxes are easy to renew as the toy wears.

Cons

• Once you add stain, paint or a coloured finish, the lead and other-element question becomes yours to answer.
• A finish that is "food safe" is not automatically "toy safe", and the reverse is also true. The rules are separate (21 CFR 175.300 for food-contact coatings, 16 CFR 1250 for toys).
• I could not open ASTM F963 (it is paywalled), so this entry quotes no heavy-element limits.

Suitability

Good: wooden blocks, pull-toys and rattles in dense hardwoods such as Hard maple and European beech, oiled or waxed. Not suited: very porous or splintery woods for anything mouthed, and any mixed-use object, such as a play kitchen with hot-glued parts, where the finish is only one of the risks.

Mouthing is the case that drives the guidance. The Forest Products Laboratory's finishing note on bowls, butcher blocks and toys lists drying oils (linseed, tung), non-drying oils and paraffin wax as options, says "baby oil" should not be used, and says to let treated items dry for several weeks and to check with the manufacturer or FDA if uncertain. Osmo's UK site has a page on finishes for toys; it is a manufacturer's statement, and the product and test details sit on that maker's data sheets, not in a regulation.

Coats and application

1. Sand to 180 to 220 (Sanding schedule) and round every edge.
2. Apply thin coats by rag or brush (Wipe-on application).
3. Wait out the cure. Drying oils harden over days to weeks; the FPL says several weeks, and a product label may give its own time. Do not hand over a toy that still smells of oil.

Compatibility

Do not add commercial paints or stains to a toy unless the maker states they meet the children's-product lead limit; paint on salvaged wood is of unknown composition (16 CFR 1303 exists because lead paint was once common), and a clear finish does not change that, so avoid salvaged painted wood for toys. See Milk paint for a pigment-based option, and note that its suitability depends on the pigments and maker, which you must check.

Care and repair

Wipe with a damp cloth, not a soaking one. Re-oil sparingly. Sand out rough spots. Discard anything with a flaking film.

Safety and environment

Heavy-metal driers: some boiled oils contain metallic driers; Tried & True (a manufacturer) says cobalt and manganese driers are carcinogens and makes polymerized linseed without them. I could not verify the health claim independently. Safer practice is to pick a product with a data sheet that states its driers. Oily rags still self-heat: Oily rag safety. For items that go in the mouth or on a plate see Food-safe finishes.
