Ingredient ratings and evidence
Higher-risk flags first. Open an ingredient for evidence.
Parfum
Low risk
Umbrella term for an undisclosed fragrance blend. It’s not usually a pregnancy-specific concern at normal cosmetic use levels, but the exact components and concentrations aren’t fully disclosed on the label, so we score it more conservatively. If you prefer maximum transparency (or you’re sensitive to fragrance compounds), choose fragrance-free/unscented products.

Disodium Laureth Sulfosuccinate
No known risks
An anionic surfactant used mainly in gentle cleansers and shampoos. Cosmetic safety reviewers concluded that alkyl PEG sulfosuccinates, including disodium laureth sulfosuccinate, are safe in current practices when formulated to be non-irritating and manufactured with appropriate impurity controls.

Sodium Cocoyl Isethionate
No known risks
Sodium cocoyl isethionate is a cleansing surfactant. The Cosmetic Ingredient Review concluded that isethionate salts are safe in current cosmetic use when formulated to be non-irritating, and reviewed reproductive and developmental data did not identify a pregnancy-specific signal.

1,2-Hexanediol
No known risks
1,2-Hexanediol is commonly used as a solvent and preservative booster; topical exposure is low and it has no known pregnancy or breastfeeding concerns at cosmetic concentrations, though very sensitive skin may occasionally react.
Sources: CIR; EU/UK Cosmetics Regulation
Coco-Glucoside
No known risks
This glucose-derived nonionic surfactant or emulsifier is used in cleansers and emulsions. The Cosmetic Ingredient Review concluded that alkyl glucosides are safe in current cosmetic use when formulated to be non-irritating; sensitive skin can still react to surfactants.

Snail Secretion Filtrate
No known risks
An animal-derived protein, peptide or secretion filtrate used for hydration and skin conditioning. These large components are expected to have low systemic absorption through intact skin. No pregnancy-specific hazard signal was identified for normal topical cosmetic use. Cosmetic-grade materials should be processed to control microorganisms, infectious agents and source-derived impurities, and protein allergy remains possible.

Questions about this assessment
Why does COSRX Advanced Snail Mucin Gel Cleanser have a Low risk rating?
The recorded formula includes 1 ingredient entry with a risk flag: Parfum (Low risk). These are ingredient-level flags; they do not replace the stored product assessment or account for every formulation detail. The product score is a stored assessment, not a clinical safety guarantee.
Has every ingredient in COSRX Advanced Snail Mucin Gel Cleanser been assessed?
20 of 20 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 Advanced Snail Mucin Gel Cleanser?
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.
