Ingredients

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

Ethylhexyl Methoxycinnamate

Medium Risk

Ethylhexyl methoxycinnamate (EHMC) is a UV-B filter (also called octinoxate/octyl methoxycinnamate). SCCS characterised EHMC as endocrine-active (oestrogenic activity and weak anti-androgenic activity in vitro and in vivo) and reviewed genotoxicity/reproductive toxicity datasets in its re-evaluation. Pregnancy-specific human outcome data for topical exposure are limited; the medium-risk signal is endocrine activity plus systemic exposure uncertainty with frequent, large-area use.

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.

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.

Isohexadecane

No Known Risks

Low-viscosity isoparaffin emollient used for slip and lightweight texture. Reviewed cosmetic safety sources support normal topical use, with no pregnancy- or breastfeeding-specific topical signal identified in the material reviewed.

Sources: CIR: Safety Assessment of Isoparaffins as Used in Cosmetics / CIR Quick Reference Table (Isohexadecane); EU CosIng / cosmetics regulatory inventory

C13-14 Isoparaffin

No Known Risks

A purified branched hydrocarbon used as an emollient, solvent and texture agent. Cosmetic safety reviewers concluded that the assessed isoparaffins, including C13-14 isoparaffin, are safe in current practices of use and concentration.

Sources: CIR: Isoparaffins conclusion, IJT 31(Suppl. 3), 2012; December 2025 Quick Reference Table https://cir-safety.org/sites/default/files/QRT-Update-Dec2025.pdf

Coco-Caprylate

No Known Risks

A coconut-fatty-alcohol and caprylic-acid ester used as a lightweight emollient. Cosmetic safety reviewers included coco-caprylate in the alkyl ester group and concluded that the group is safe in current practices when formulated to be non-irritating. No pregnancy-specific concern was identified for normal topical use.

Phenyl Trimethicone

No Known Risks

Silicone emollient used to improve slip, gloss, and water resistance. Reviewed cosmetic safety sources support normal topical use, with no pregnancy- or breastfeeding-specific topical signal identified in the material reviewed.

Bis-Aminopropyl Diglycol Dimaleate

No Known Risks

Propanediol

No Known Risks

Solvent and humectant used to improve texture and ingredient solubility. Low systemic exposure expected from topical cosmetic use.

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

Zea Mays Oil

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.

Beta-Carotene

No Known Risks

A colour additive used in cosmetics. FDA lists caramel and beta-carotene as permitted cosmetic colour additives, including for eye-area and general cosmetic use, subject to applicable identity, purity and manufacturing requirements. No pregnancy-specific concern was identified from normal topical cosmetic exposure.

Sources: FDA: Color Additives Permitted for Use in Cosmetics https://www.fda.gov/cosmetics/cosmetic-ingredient-names/color-additives-permitted-use-cosmetics; 21 CFR Part 73.

Helianthus Annuus Seed Oil

No Known Risks

Helianthus annuus (sunflower) seed oil is a common emollient rich in fatty acids and is generally well tolerated, with no known pregnancy or breastfeeding concerns in topical cosmetic use.

Sources: CIR; EU/UK Cosmetics Regulation

Moringa Oleifera Seed Oil

No Known Risks

This plant-derived fatty oil or butter is used as an emollient and skin-conditioning ingredient. The Cosmetic Ingredient Review concluded that assessed plant-derived fatty acid oils are safe as used in cosmetics; individual plant allergy and ingredient purity remain practical considerations.

Sources: CIR: Safety Assessment of Plant-Derived Fatty Acid Oils https://cir-reports.cir-safety.org/view-attachment/?id=ad62ac6b-8e74-ec11-8943-0022482f06a6

Punica Granatum Seed Oil

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.

Water

No Known Risks

Morinda Citrifolia Seed Powder

No Known Risks

Hexyl Cinnamal

No Known Risks

A synthetic floral fragrance ingredient. Its main consumer-relevant concern is skin sensitisation in susceptible users; no pregnancy-specific hazard is identified for normal topical cosmetic exposure.

Eclipta Prostrata Extract

No Known Risks

A plant-part extract used for skin conditioning, soothing, fragrance or antioxidant support. No pregnancy-specific systemic signal was identified for normal topical cosmetic exposure. This assessment does not extend to essential oils, oral herbal products or medicinal doses, and botanical sensitivity remains possible.

Limonene

No Known Risks

Limonene is a common fragrance component used at low levels in cosmetics; it is not a pregnancy-specific concern in topical use, but it is a recognised fragrance allergen and may trigger irritation or sensitisation in some people, especially if the product oxidises over time.

Sources: EU/UK cosmetics (fragrance allergen labelling); IFRA; toxicology reviews

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.

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

Citral

No Known Risks

A lemon-scented mixture of the aldehydes geranial and neral used in fragrance. Citral is a recognised skin sensitiser, but current cosmetic concerns relate to allergy and concentration rather than a pregnancy-specific hazard from normal topical use.

Sources: European Commission: Fragrance allergens labelling https://single-market-economy.ec.europa.eu/sectors/cosmetics/cosmetic-products-specific-topics/fragrance-allergens-labelling_en; SCCS fragrance-allergen opinions

Linalool

No Known Risks

Sources: EU/UK cosmetics (fragrance allergen labelling); IFRA; toxicology reviews

Melia Azadirachta Leaf Extract

No Known Risks

Neem leaf extract is used topically for skin conditioning and antimicrobial support. Reproductive concerns reported for concentrated neem seed preparations, intrauterine exposure, or high oral doses do not establish a hazard from normal topical cosmetic exposure to a leaf extract.

Sources: PubMed: oral purified neem seed extracts in primates https://pubmed.ncbi.nlm.nih.gov/8773426/; PubMed: intrauterine neem oil in primates https://pubmed.ncbi.nlm.nih.gov/8143455/; European Commission CosIng ingredient inventory. No human pregnancy study of normal topical cosmetic leaf-extract use was identified.

Citronellol

No Known Risks

A rose-like fragrance ingredient that occurs naturally in many essential oils and may also be manufactured. Its main cosmetic concern is contact allergy in susceptible users; no pregnancy-specific hazard is identified for normal topical cosmetic exposure.

Sources: European Commission: Fragrance allergens labelling https://single-market-economy.ec.europa.eu/sectors/cosmetics/cosmetic-products-specific-topics/fragrance-allergens-labelling_en; SCCS fragrance-allergen opinions

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.
