Ingredients

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

Cyclohexasiloxane

Low Risk

A volatile cyclic silicone also known as D6, used for slip and quick-drying texture. Normal topical exposure is expected to be limited, but exact-ingredient pregnancy evidence is limited and cyclic siloxanes have route-specific toxicology and regulatory considerations. MamaSkin therefore classifies it as low risk rather than a pregnancy contraindication.

Trimethylsiloxysilicate

Low Risk

A silicone resin used as a film former in long-wear makeup, sunscreen and hair products. Cosmetic safety reviewers concluded it is safe in current use when the finished product is not irritating or sensitizing to the respiratory tract. MamaSkin classifies it as low risk because the qualification depends on formulation and inhalation route rather than a known pregnancy-specific hazard from normal topical use.

Sources: CIR: Safety Assessment of Silylates and Surface-Modified Siloxysilicates; International Journal of Toxicology 32(Suppl. 1):5-24 (2013) https://cir-safety.org/ingredient/trimethylsiloxysilicate

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.

Show all (34)

Dipotassium Glycyrrhizate

Low Risk

A purified glycyrrhizic-acid salt used as a soothing and skin-conditioning ingredient. Cosmetic safety reviewers concluded that dipotassium glycyrrhizate is safe in current cosmetic use and noted poor dermal absorption. MamaSkin nevertheless applies a cautious low-risk classification for consistency with the existing licorice family because high oral glycyrrhizin exposure has pregnancy-related concerns; this is not a topical contraindication.

Ethyl Ferulate

Low Risk

Ethyl ferulate is an ester of ferulic acid used as an antioxidant/skin-protecting ingredient (often in photoprotection-support formulas). Available cosmetic literature describes it mainly as a topical antioxidant with low systemic concern at typical use; the main practical issue is potential irritation in sensitive skin at higher concentrations or in alcohol-heavy formulas. It is not a typical pregnancy-specific concern in topical cosmetic use.

Sources: Nazaré et al.: Topical ethyl ferulate formulation study https://pmc.ncbi.nlm.nih.gov/articles/PMC6271385/

Butyloctyl Salicylate

Low Risk

Butyloctyl salicylate is a salicylate ester that the CIR panel considered safe as used in cosmetics when formulated to be non-irritating. Available safety data support low dermal toxicity, and at typical cosmetic use levels the expected systemic salicylate exposure from topical application is far below oral salicylate exposure, which fits a low-risk classification.

Water

No Known Risks

Zinc Oxide

No Known Risks

Mineral ingredient used as a UV filter and skin protectant in many creams and mineral sunscreens. For typical topical use, systemic absorption is very low and it is generally considered acceptable in pregnancy and breastfeeding. If you prefer a cautious approach, avoid inhaling loose powders or spray formats.

Sources: General dermatology/obstetric guidance commonly lists mineral sunscreens (zinc oxide) as acceptable in pregnancy; exposure route considerations for powders/sprays.

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)

Dicaprylyl Carbonate

No Known Risks

Sources: CIR: Safety Assessment of Dialkyl Carbonates as Used in Cosmetics; EU CosIng / cosmetics regulatory inventory

Propylheptyl Caprylate

No Known Risks

A fatty-acid ester used mainly for emollience, slip and formula texture. Cosmetic safety reviewers concluded that the assessed alkyl esters are safe in current practices when formulated to be non-irritating. No pregnancy-specific concern was identified for normal topical cosmetic exposure.

Sources: CIR: Safety Assessment of Alkyl Esters as Used in Cosmetics https://cir-reports.cir-safety.org/view-attachment/?id=b34bc38f-8e74-ec11-8943-0022482f06a6

Disiloxane

No Known Risks

Disiloxane is a volatile silicone used as a solvent and texture aid. No reproductive or developmental hazard signal relevant to normal topical cosmetic exposure was identified in the reviewed cosmetic and substance information. Volatility and flammability are product-handling considerations rather than pregnancy-specific hazards.

Sources: European Commission CosIng ingredient inventory; ECHA substance information for disiloxane; CIR silicone ingredient safety assessments for related cosmetic-use materials. No ingredient-specific topical pregnancy studies were identified.

Pentylene Glycol

No Known Risks

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.
