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.

Dimethicone

Low Risk

Dimethicone is a silicone polymer used as a skin protectant and slip/conditioning agent. It is considered inert with minimal dermal absorption; the main practical issues are cosmetic (feel) and occasional irritation in very sensitive users. It is not a pregnancy-specific concern in topical cosmetic use.

Water

No Known Risks
Show all (16)

Panthenol

No Known Risks

Panthenol (pro-vitamin B5) is used for soothing and barrier support and is generally well tolerated, with no known pregnancy or breastfeeding concerns in topical cosmetic use.

Sources: CIR; EU/UK Cosmetics Regulation

Glycerin

No Known Risks

Glycerin is a widely used humectant that supports hydration and the skin barrier, with a long safety record and no known pregnancy or breastfeeding concerns in topical cosmetic use.

Sources: CIR; EU/UK Cosmetics Regulation

Alcohol Denat.

No Known Risks

Volatile solvent used to improve texture, drying time, and penetration in some formulas. Reviewed cosmetic safety sources support current cosmetic use, with no pregnancy- or breastfeeding-specific topical concern identified in the material reviewed; the main practical issue is dryness, stinging, or barrier disruption in some users.

Hydroxyethylpiperazine Ethane Sulfonic Acid

No Known Risks

HEPES is a zwitterionic pH buffer. Its function and expected topical exposure do not indicate a reproductive or developmental concern in normal cosmetic use.

Sources: European Commission CosIng; peer-reviewed biochemical literature on HEPES.

PEG-20 Methyl Glucose Sesquistearate

No Known Risks

peg-20 methyl glucose sesquistearate is used as a cosmetic surfactant, emulsifier or conditioning agent. Relevant cosmetic-safety assessments support use when formulated to be non-irritating and with appropriate impurity controls. Local skin or eye irritation is possible at higher concentrations, but no pregnancy-specific concern was identified for normal topical or rinse-off use.

Sodium Hyaluronate

No Known Risks

Sodium hyaluronate (hyaluronic acid salt) is used for hydration and cushioning, with very low systemic absorption from topical use and no known pregnancy or breastfeeding concerns at cosmetic concentrations.

Sources: CIR; EU/UK Cosmetics Regulation

Ammonium Polyacryloyldimethyl Taurate

No Known Risks

A high-molecular-weight polymer used to thicken and stabilise formulas. Cosmetic safety reviewers concluded that acryloyldimethyltaurate polymers are safe in current cosmetic practices. Absorption of the finished polymer is expected to be limited, with residual monomers controlled during manufacture.

Caprylyl Glycol

No Known Risks

Humectant and preservative booster used to support product stability. Low systemic exposure expected from topical cosmetic use.

Sources: Scientific Committee on Consumer Safety (EU); Cosmetic Ingredient Review (US)

Vitreoscilla Ferment

No Known Risks

vitreoscilla ferment is a fermentation-derived or microbial lysate cosmetic conditioning material. The assessment applies to the defined non-live cosmetic ingredient rather than live organisms or oral supplements. No pregnancy-specific concern was identified for normal topical use; formulation purity and sensitivity remain relevant.

Citric Acid

No Known Risks

pH adjuster used in small amounts to maintain product stability. Not associated with pregnancy-specific concerns.

Sources: Scientific Committee on Consumer Safety (EU); European cosmetics regulatory framework

Xanthan Gum

No Known Risks

Natural polysaccharide thickener used for stability and texture. Not associated with pregnancy-specific concerns.

Sources: European cosmetics regulatory framework

Octyldodecanol

No Known Risks

Fatty alcohol emollient used to improve spreadability and reduce drag. Reviewed cosmetic safety sources support normal topical use, with no pregnancy- or breastfeeding-specific topical signal identified in the material reviewed.

Sources: CIR ingredient status / report data sheet for Octyldodecanol; EU CosIng / cosmetics regulatory inventory

Tocopherol

No Known Risks

Vitamin E antioxidant used to protect oils and support the skin barrier. Not associated with pregnancy-specific concerns at 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.
