Baby Safety / Compounds / 1,1,2,2-Tetrachloroethane

Is 1,1,2,2-Tetrachloroethane safe for babies and kids?

High risk for kids

Infants are more vulnerable to 1,1,2,2-Tetrachloroethane than children or adults due to immature hepatic/renal clearance, higher intake-to-body-weight ratio, rapid organ development, and increased gastrointestinal absorption.

Risk for babies

High risk

Infants are more vulnerable to 1,1,2,2-Tetrachloroethane 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.

What to do: Minimize infant exposure through source control. For breastfeeding mothers: reduce maternal exposure. For formula-fed infants: use certified low-migration bottles and verified water sources. Consult pediatrician regarding any concerns.

Risk for pregnant and nursing people

Context-dependent

Pregnancy alters the metabolism and distribution of 1,1,2,2-Tetrachloroethane, 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.

What to do: Minimize exposure during pregnancy and lactation. Consult healthcare provider regarding specific risks. Consider alternative products with lower hazard profiles.

Regulatory consensus

1 regulatory bodyhas classified 1,1,2,2-Tetrachloroethane.

AgencyYearClassificationNotes
Unknown

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 1,1,2,2-tetrachloroethane

  • Consumer Productspharmaceutical/industrial use

Safer alternatives

Lower-risk approaches that achieve a similar outcome to 1,1,2,2-Tetrachloroethane:

  • Point-of-use filtration; Alternative disinfection (UV, ozone)
    Trade-offs: Powerful oxidant; effective for taste/odor and micropollutants; decomposes to oxygen (no residual); forms bromate in bromide-containing water; capital cost moderate; operational complexity higher than chlorination.
    Relative cost: 1.2-2×
