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.

No Known Risks

Palmitoyl Tetrapeptide-10

No Known Risks

Zingiber Officinale Root Extract

No Known Risks

A ginger root extract used mainly for skin conditioning and fragrance support. Cosmetic safety reviewers concluded that the assessed Zingiber officinale root-derived ingredients are safe in current practices when formulated to be non-sensitising. This topical cosmetic conclusion should not be read as advice about ingesting concentrated ginger supplements.

Astrocaryum Murumuru Seed Butter

No Known Risks

A plant-derived fatty oil or butter used mainly as an emollient, conditioning ingredient or texture agent. Cosmetic safety reviewers concluded that the assessed plant-derived fatty acid oils are safe in current practices of use and concentration. This conclusion applies to cosmetic-grade fixed oils rather than similarly named volatile essential oils. Seed or food allergy may still matter for a susceptible person.

No Known Risks

Bisabolol

No Known Risks

A terpene alcohol used for skin conditioning and soothing. Cosmetic safety reviewers reaffirmed bisabolol as safe at current cosmetic concentrations, and reproductive and developmental testing did not identify adverse effects. Bisabolol can increase skin penetration, so formulators should consider the safety of other ingredients in the same product.

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.
