Is Polydimethylsiloxane (PDMS) safe for babies and kids?
Moderate risk for kidsInfants are more vulnerable to Polydimethylsiloxane (PDMS) than children or adults due to immature hepatic/renal clearance, higher intake-to-body-weight ratio, rapid organ development, and increased gastrointestinal absorption.
What is polydimethylsiloxane (pdms)?
Also known as: Siloxanes and Silicones, di-Me, dimetil polissiloxano, poli(dimetylosiloksan), polydiméthylsiloxane.

- 63148-62-9
Risk for babies
Moderate riskInfants are more vulnerable to Polydimethylsiloxane (PDMS) than children or adults due to immature hepatic/renal clearance, higher intake-to-body-weight ratio, rapid organ development, and increased gastrointestinal absorption.
Neonates and infants up to 12 months have incomplete blood-brain barrier development, immature Phase I/II metabolic enzymes (particularly CYP3A4, UGT1A1), and higher gastrointestinal permeability. Equivalent doses produce higher internal concentrations and longer residence times.
Risk for pregnant and nursing people
Context-dependentPregnancy alters the metabolism and distribution of Polydimethylsiloxane (PDMS), potentially increasing fetal exposure. The developing embryo/fetus is vulnerable during organogenesis (weeks 3-8) and neurological development. Placental transfer should be assumed.
No specific reproductive toxicity data identified, but pregnancy-specific safety data is limited for most chemicals. Precautionary minimization of exposure is recommended.
Regulatory consensus
1 regulatory bodyhas classified Polydimethylsiloxane (PDMS).
| Agency | Year | Classification | Notes |
|---|---|---|---|
| EPA CTX / Genetox | — | Genotoxicity: positive (Ames: positive, 3 positive / 1 negative reports) |
Regulators apply different standards of evidence — animal-data weighting, exposure-pattern assumptions, epidemiological power thresholds — which is why two scientific bodies can review the same data and reach different conclusions. The disagreement is the data.
Where kids encounter polydimethylsiloxane (pdms)
- Consumer Products — Silicone cookware, Silicone sealants, Cosmetics, Medical devices, Food processing
Safer alternatives
Lower-risk approaches that achieve a similar outcome to Polydimethylsiloxane (PDMS):
-
Fragrance-free formulations
Trade-offs: Consumer preference for scented productsRelative cost: Lower (ingredient elimination)
-
Essential oil-based fragrances (with disclosure)
Trade-offs: Natural does not mean safe — many essential oils are skin sensitizersRelative cost: 2-5× conventional
