Ingredients

Ingredients with a higher risk flag appear first, followed by the rest of the formula.

Phenoxyethanol

Low Risk

Phenoxyethanol is a preservative permitted in EU cosmetics up to 1.0%. The SCCS concluded it is safe for cosmetic use at that level, including when considering higher cosmetic exposure scenarios in infants and young children. Main practical concern is irritation/stinging on very sensitive or compromised skin rather than a pregnancy- or breastfeeding-specific risk.

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.

How to use this assessment

The risk band is the primary conclusion. The score adds detail within that band and should not be used to compare products as if a one-point difference were clinically meaningful.

MamaSkin provides pregnancy-focused information, not medical advice. Your midwife, GP, pharmacist or dermatologist should take priority when your circumstances differ from typical cosmetic use.
