Baby Silicone Safety Guide: Materials and Standards for Teethers, Spoons and Plates

Short answer: for baby silicone that goes in the mouth, safety comes down to exactly two things — a food-contact grade and a third-party test report for your target market. Colour, softness, smell and price prove nothing; and a "food-grade" claim that exists only as a sales sentence is no claim at all.

Why baby parts face stricter rules than adult food-contact parts

Three factors stack up: sustained mouth contact (a teether gets chewed for hours), repeated high-temperature cycles (bottles and bowls go through steam or boiling water again and again), and population differences — infants tolerate lower migration levels, and the regulatory limits themselves are tighter. So "usable" and "compliant" are two separate lines, each needing its own verification.

Which standards apply: one table by market

Choosing the material: why platinum cure is the default for baby parts

Same silicone, different cure systems, different byproducts. Peroxide cure leaves decomposition residues that must be driven off by post-curing; platinum addition cure produces none of these, with markedly lower odour and extractables — which is why food-contact and infant applications default to platinum. The cost is higher material prices and sensitivity to contaminants (sulphur or amines can poison the catalyst). For the full comparison see platinum cure vs peroxide cure.

Four common myths

Myth 1: light colours mean safe

Colour comes from the masterbatch and has nothing to do with compliance. A clear or pastel part can still be an industrial-grade compound. The only valid evidence is grade plus report.

Myth 2: no smell means good rubber

Odour is a rough indicator at best, and masking grows with time. Peroxide residues smell strongest right out of the box and fade within days — but the residue itself has not gone anywhere.

Myth 3: expensive means compliant

Price reflects material and processing cost, not verification. The real red flag is a quote far below market that still claims food grade — and the correct response is to ask for the grade and the report.

Myth 4: a raw-material report covers the finished part

No. A raw-material report applies only to the samples submitted, while the finished part passes through mixing, curing, printing and packing — where release agents and cross-contamination can change the outcome. Material compliance is necessary but not sufficient; finished parts are tested separately for the target market.

Sourcing checklist

• Get the compound grade — do not accept a vague "food grade"
• Check the report subject: raw material or finished part, and who commissioned it
• Match test items to your target market (GB 4806 / LFGB / FDA / CPSIA / EN 14350)
• Treat "food contact" and "baby-specific" as two separate requirements — both are needed
• Confirm the cure system (platinum preferred for baby parts) and whether post-curing is required
• Confirm inks and masterbatches also meet food-contact requirements
• Request batch traceability records and AQL sampling standards
• Sample first, then scale — on the first cooperation especially

FAQ

Do teethers have to be platinum-cured?

Not a legal mandate, but it is industry practice. Infant items face the tightest volatile and extractable limits, and platinum systems start with an advantage; peroxide systems can in principle comply but rely on post-curing and thorough testing to get there. Put the cure system in your RFQ as an explicit field rather than leaving it to the supplier’s default.

What is the difference between food-grade and medical-grade silicone?

Two different frameworks. Food grade is assessed against food-contact rules (migration, sensory, volatiles); medical grade against biocompatibility (ISO 10993 series) and sterilization compatibility. A part can satisfy both, but a food-contact report cannot substitute for medical validation, or vice versa.

Do you make baby silicone parts?

Yes. We mould teethers, feeding spoons, divided plates, bibs and sippy cups — see the baby silicone range for the full list. Our silicone raw materials are covered by SGS reports spanning 12 regulations (including GB 4806.16-2025, FDA 21 CFR 177.2600, LFGB and EN 71-3), all Pass or Not Detected, with report numbers and PDFs on the compliance page. Finished parts can be submitted for separate testing per your market.

LXYSILICONE moulds baby silicone parts to order — standard ranges start at 50 pieces with 5–7 working day sampling. Put your target market and required test items in the enquiry, and we will come back with a process and quote against the matching product range.
