Frequently asked questions

Is sodium trideceth sulfate safe during pregnancy?
No harmonised CLP reproductive classification (ECHA Annex VI) or SCCS/CIR reproductive restriction is known for sodium trideceth sulfate; available authoritative cosmetic safety assessments (CIR/SCCS) have focused on related anionic surfactants (e.g., SLES/SLS) without reproductive flags. Peer‑reviewed/reprotoxic evidence specific to sodium trideceth sulfate is not available. Dermal absorption of ethoxylated sulfate surfactants is generally low but measurable for topical use, so exposure is scored as low (ECHA dossiers / PubChem list physicochemical properties consistent with low systemic uptake).
Is sodium trideceth sulfate safe while breastfeeding?
No data indicating reproductive or lactation-specific toxicity; no harmonised classification for reproductive effects. Maternal dermal systemic absorption from cosmetics is expected to be low but measurable, so potential for minimal transfer via breastmilk is low (consistent with general surfactant data in PubChem and ECHA registration dossiers).
Is sodium trideceth sulfate safe for baby skin?
No infant‑specific reproductive or developmental hazards identified. However, because infant (0–3 yr) skin has a higher surface‑area‑to‑weight ratio and immature barrier function, absorption potential is increased versus adults; therefore exposure score is increased by +1 relative to adult topical use. Primary concerns for infants would come from manufacturing impurities (e.g., 1,4‑dioxane) rather than the sulfate surfactant itself.
How does VeriMom score sodium trideceth sulfate?
VeriMom scores sodium trideceth sulfate at 93/100 (no known risks) based on EU CosIng status, ECHA hazard classifications, and peer-reviewed PubMed studies. Our scoring pipeline is fully transparent.
