Animal developmental findings occurred at high doses that also caused maternal toxicity, while CIR concluded that normal cosmetic use is safe. This is a cautious classification, not a known human pregnancy contraindication.

Ingredient ratings and evidence

Higher-risk flags first. Open an ingredient for evidence.

Ethyl Hexanediol

Low risk

Ethyl Hexanediol is an aliphatic alcohol used mainly as a cosmetic solvent. It can be absorbed through skin. Animal studies reported developmental effects after high oral and dermal doses, but those effects occurred at doses that also caused substantial maternal toxicity. CIR concluded that the ingredient is safe as cosmetically used and later reaffirmed that conclusion. MamaSkin nevertheless classifies it as low risk under its precautionary pregnancy-screening policy; this is not a known human pregnancy contraindication at normal cosmetic exposure.

Questions about this assessment

Why does COSRX Centella Water Alcohol-Free Toner have a Low risk rating?

Manual review 2026-07-22: the formula contains Ethyl Hexanediol, classified as Low Risk under MamaSkin's precautionary pregnancy policy. Animal developmental findings occurred at high doses that also caused maternal toxicity, while CIR concluded that normal cosmetic use is safe. This is a cautious classification, not a known human pregnancy contraindication. The product score is a stored assessment, not a clinical safety guarantee.

Does a barrier-care product name establish pregnancy suitability?

No. This recorded formula contains Panthenol or Madecassoside, but a barrier-care claim does not establish the assessment of all its other ingredients. Read the individual ingredient evidence and any manual-review explanation, and compare the recorded list with your packaging.

Has every ingredient in COSRX Centella Water Alcohol-Free Toner been assessed?

9 of 9 ingredient entries on this page have a recorded score, evidence summary and source text. That describes documentation coverage, not proof that the finished formula has been clinically tested during pregnancy.

Does this assessment apply to my COSRX Centella Water Alcohol-Free Toner?

Only if the ingredient list on your packaging matches the recorded formula shown here. Formulas can differ by market and change over time. Compare the full list, not just the product name; report a mismatch if it differs.

Does this pregnancy assessment also establish breastfeeding suitability?

No. This page presents a pregnancy-focused product assessment. Do not infer a breastfeeding conclusion from its score or label; breastfeeding requires a separate assessment of the formula and how it is used.
