Ingredient ratings and evidence
Higher-risk flags first. Open an ingredient for evidence.
Fragrance (Parfum)
Low risk
An exact label variant for an undisclosed fragrance blend. Fragrance is not usually a pregnancy-specific concern at normal cosmetic levels, but the precise components and concentrations are not fully disclosed, so MamaSkin scores the umbrella term conservatively. People sensitive to fragrance may prefer fragrance-free 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.

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.

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 (Corn) Oil
No known risks
Zea Mays (Corn) Oil: A plant-derived fixed fatty oil assessed for cosmetic emollient use, not a volatile essential oil or whole-plant extract. Refining, oxidation control, source allergy and possible residual allergenic proteins remain relevant. This assessment does not establish safety of ingestion or medicinal doses. No pregnancy-specific harm has been identified for ordinary topical cosmetic use; direct human pregnancy data are limited.

Beta-Carotene
No known risks

Helianthus Annuus (Sunflower) 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/Aqua/Eau
No known risks
Purified water, distilled water and Aqua are names or grades of water used as a cosmetic solvent. No pregnancy-specific risk is identified from ordinary topical use.

Morinda Citrifolia Fruit Extract
No known risks
morinda citrifolia fruit extract is a botanical-derived cosmetic conditioning ingredient. The reviewed identity is not an essential oil or an oral herbal preparation. Available cosmetic evidence and expected topical exposure did not identify a pregnancy-specific contraindication, although botanical irritation or allergy remains possible.

18 of 21 ingredient entries on this page have a recorded score, evidence summary and source text. 3 entries do not have all of those fields. Unmatched or unrated entries are marked Not assessed in grey; missing evidence does not establish safety.
Does this assessment apply to my Olaplex No.7 Bonding Oil?
Only if the ingredient list on your packaging matches the recorded formula shown here. Formulas can differ by market and change over time. Compare the full list, not just the product name; report a mismatch if it differs.
Does this pregnancy assessment also establish breastfeeding suitability?
