Chemical Safety Requirements for Silicone Toys

Silicone toys for infants and children must meet strict chemical safety standards to ensure non-toxicity, with global limits on heavy metals, phthalates, residual monomers, and migration. Below is a comprehensive guide to compliance requirements and testing protocols.

Heavy Metal Migration Limits (mg/kg)

Key elements restricted by EU EN 71-3, US CPSIA/ASTM F633, and China GB 6755:

ElementEU EN 71-3US CPSIA/ASTM F633China GB 6755
Lead (Pb)≤23≤100 (≤90 in paint)≤90
Cadmium (Cd)≤17≤75≤75
Arsenic (As)≤77≤25≤25
Mercury (Hg)≤77≤10≤10
Chromium (VI)≤0.033≤0.03≤0.03

Test method: ICP-OES/ICP-MS with 4% acetic acid extraction (70°C/2hr for EN 71-3).

Phthalate Limits (6 High-Risk Types)

Global standard: All 6 phthalates ≤0.1% (1,000 ppm) by weight for children’s products ≤12 years:

• DEHP, DBP, BBP (banned in all toys; ≤0.1% in all components)

• DINP, DIDP, DNOP (≤0.1% in mouthable toys; stricter for infants<3 years)

Test method: GC-MS for quantitative analysis of each phthalate.

Banned Additives & Residual Monomers

Zero tolerance: BPA, PVC, formaldehyde, nitrosamines, organotins (TBT/DBT)

• Residual monomers: Vinyl siloxane ≤0.1%; D4/D5/D6 siloxanes ≤0.1% (EU REACH SVHC)

• Platinum catalyst residues: ≤5 ppm (medical-grade silicone); peroxide curing byproducts banned

• VOCs: Total volatile organic compounds ≤0.5% (5,000 ppm) (EU REACH/China GB 8806.16)

Food-Contact & Migration Requirements

US FDA 21 CFR 177.6600: No migration of BPA/phthalates/heavy metals; stable at 200°C; non-toxic/non-irritating

EU LFGB (Germany): Stricter migration limits; no odor/taste transfer; nitrosamine/VOC testing

China GB 8806.16-2025: Lead ≤0.01 mg/kg, arsenic ≤0.002 mg/kg (10× stricter); migration test (4% acetic acid, 77°C/24h)

Regional Compliance Mandates

US: CPSIA + ASTM F633; CPC certification required (test reports from accredited labs)

EU: EN 71-3 + REACH; CE marking required (SVHC reporting for D4/D5/D6 siloxanes)

China: GB 6755 + GB 8806.16; CCC certification required (lead ≤90 ppm; phthalates ≤0.1%)

Compliance Checklist for Manufacturers

  • Use only platinum-cured food-grade/medical-grade silicone (avoid peroxide curing)

  • Test heavy metal migration via ICP-OES/ICP-MS (meet EN 71-3/CPSIA limits)

  • Verify 6 phthalates ≤0.1% with GC-MS; ban BPA/PVC/formaldehyde

  • Check residual monomers (VSM/D4/D5/D6 ≤0.1%) and VOCs ≤0.5%

  • Obtain FDA/LFGB certification for mouthable toys; retain test reports for 5+ years

  • Label with CE (EU) or CPC (US) marks; include material grade and compliance statements
