Melaleuca Alternifolia Leaf Oil
Low risk
An exact label variant for tea tree essential oil. The SCCS concluded that tea tree oil is safe only in specific defended adult dermal product types and concentrations, excluded aerosolised and sprayable formats, and identified it as a moderate skin sensitiser. MamaSkin therefore classifies it as low risk because safety is formulation- and route-dependent, not because it is a pregnancy contraindication.

Betaine Salicylate
Low risk
Ester form of salicylic acid; hydrolyses to SA, low-strength topical use shows negligible systemic absorption - chemical peels ≥30 % should be avoided.
Sources: MotherToBaby: Topical acne treatments including salicylic acid https://www.ncbi.nlm.nih.gov/books/NBK582985/
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.

Cocamidopropyl Betaine
No known risks
Mild amphoteric surfactant used in cleansers and shampoos to boost foam and reduce harshness.

Has every ingredient in COSRX Low pH Good Morning Gel Cleanser been assessed?
24 of 25 ingredient entries on this page have a recorded score, evidence summary and source text. 1 entry does not have all of those fields. Unmatched or unrated entries are marked Not assessed in grey; missing evidence does not establish safety.
Does this assessment apply to my COSRX Low pH Good Morning 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.
