Rosmarinus Officinalis Leaf Oil

High Risk

Rosmarinus officinalis (rosemary) leaf oil is a concentrated fragrance essential oil with chemotype-dependent constituents (often including camphor/1,8-cineole). Pregnancy-specific evidence for topical cosmetic exposure is limited, and camphor-rich oils are commonly advised to avoid in pregnancy; combined with irritation/sensitisation potential, this supports a precautionary high-risk classification—especially in leave-on products.

Salvia Hispanica Seed Oil

No Known Risks

A triglyceride-rich plant oil or oil fraction used as an emollient and skin conditioner. Plant-derived fatty oils have low systemic toxicity and cosmetic review focuses mainly on irritation, sensitisation and source allergy. No pregnancy-specific hazard was identified for normal topical exposure.

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.

Lavandula Angustifolia Oil

No Known Risks

Lavender oil is used in cosmetics mainly as a fragrance ingredient. For normal diluted topical cosmetic use, current evidence does not establish a pregnancy-specific concern. This assessment does not cover ingestion, concentrated essential-oil use, or aromatherapy-style exposure. The more relevant practical issues in skincare are irritation or sensitisation in some users, so within this methodology it remains in no known risks.

Anthemis Nobilis Flower Oil

No Known Risks

A Roman chamomile flower extract or oil used for skin conditioning and fragrance. Cosmetic safety reviewers concluded that Anthemis nobilis-derived ingredients are safe in current practices when formulated to be non-sensitising.

Pogostemon Cablin Leaf Oil

No Known Risks

Patchouli leaf oil is a volatile botanical oil used mainly as a fragrance ingredient. Available cosmetic safety and fragrance standards focus on irritation, sensitisation and constituent quality.

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.
