Children's art supplies (paints, markers, glues, clay, craft sets) — child safety profile

What is this product?

Children's art supplies — including paints (finger paint, poster paint, acrylic), markers, crayons, colored pencils, glue sticks and liquid glue, modeling clay, polymer clay, and craft sets — encompass a wide range of chemical formulations with varying concern levels. The category matters because children use these products in ways that maximize chemical exposure: hand-to-mouth transfer during use, dermal contact with open pigment systems, inhalation of marker and paint solvents during close application, and accidental ingestion of clay and paint especially in young children. Lead in pigments is the historical dominant concern and remains a real risk in imported craft products. Toluene and other aromatic solvents in permanent markers and model glue represent a significant inhalation concern in enclosed spaces. Formaldehyde as a preservative in water-based paints and glues is a sensitization and carcinogen concern. Polymer clays (Fimo, Sculpey) require oven baking and release plasticizer vapors (phthalates, potentially DINP) at baking temperatures. The ACMI (Art and Craft Materials Institute) AP (Approved Product) certification provides the most meaningful third-party assessment of art supply safety for children's products.

Who's most at risk

• Infants — Developing organ systems, higher exposure per body weight, oral exploration behavior
• Children — Developing endocrine and neurological systems, higher exposure per body weight

How to use it more safely

• Use only under adult supervision appropriate to child's age
• Ensure adequate ventilation, especially with markers and paints
• Wash hands thoroughly after use to prevent ingestion of materials
• Use on washable surfaces away from skin, eyes, and mouth

Red flags — when to walk away

• Imported art supply sets with no ACMI AP certification, especially from dollar stores or unbranded online sellers — Non-ACMI-certified imported art sets are the primary source of heavy metal contamination in children's art supplies. Testing consistently finds lead, cadmium, and other heavy metal pigments above safety thresholds in these products. The absence of AP certification for products marketed to children is a significant red flag.
• Permanent markers or solvent-based glue used by children in enclosed spaces — Permanent markers emit toluene and xylene vapors — the distinctive 'permanent marker smell' is the solvent system off-gassing. Use in an enclosed bedroom or classroom with windows closed creates elevated solvent concentrations in breathing air. Children's markers and washable paints should be the only art products used in enclosed spaces by children.

Green flags — what to look for

• ACMI AP certification on product packaging with current certification year — AP certification from the Art and Craft Materials Institute is the industry standard for children's art supply safety — requires toxicological review by a board-certified toxicologist, prohibits heavy metal pigments above background, and certifies safe-even-if-ingested for children's products. This certification is the clearest available signal that the product has been assessed for the specific exposure patterns of children.

Safer alternatives

• ASTM D4236 certified art supplies — Independently tested for safety; labeled with age-appropriate warnings
• Natural plant-based paints and dyes — Lower chemical content reduces toxicity risk for young users
• Playdough and air-dry clay — Moldable alternative with minimal chemical exposure compared to craft paints
