Ingredients

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

Polyisobutene

No Known Risks

A large, mostly insoluble polymer used as a binder, film former and texture ingredient. Cosmetic safety reviewers concluded that polyisobutene is safe in current cosmetic use; slow absorption and reproductive data on related polybutene do not indicate a pregnancy-specific concern from normal topical exposure.

Phytosteryl/Isostearyl/Cetyl/Stearyl/Behenyl Dimer Dilinoleate

No Known Risks

A high-molecular-weight lipid ester used for emollience, adhesion and formula texture. Cosmetic safety reviewers concluded that the assessed dialkyl dimer dilinoleates are safe in current practices of use and concentration. Absorption of the intact ester is expected to be low.

Butyrospermum Parkii Butter

No Known Risks

Butyrospermum parkii (shea) butter is an emollient/occlusive that supports the skin barrier; topical use is considered low concern with no known pregnancy or breastfeeding risks.

Sources: CIR; EU/UK Cosmetics Regulation

Microcrystalline Wax

No Known Risks

Highly refined mineral wax used to thicken and stabilise formulas. Cosmetic-grade microcrystalline wax has minimal skin absorption and no known pregnancy-specific concerns in topical use as intended. Concerns raised online typically relate to unrefined mineral oil impurities or dietary exposure, not cosmetic-grade topical use.

Sources: Cosmetic Ingredient Review (CIR) ingredient dossier for Microcrystalline Wax + CIR wax safety assessment materials. ; Petry et al. (2017) dermal penetration review (includes mineral oils/waxes). ; BfR, Highly refined mineral oils in cosmetics (context on refined mineral oil fractions/waxes in cosmetics) (2018).

Sorbitan Sesquioleate

No Known Risks

A sorbitan fatty-acid ester used as an emulsifier and surfactant. Cosmetic safety reviewers concluded that sorbitan esters are safe in current cosmetic practices of use. Sorbitan sesquioleate can occasionally cause contact allergy and has produced reactions in a small proportion of people investigated for dermatitis, so this classification does not mean that sensitive skin cannot react. No pregnancy-specific concern was identified for normal topical cosmetic exposure.

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

Butylene/Ethylene/Styrene Copolymer

No Known Risks

A high-molecular-weight hydrocarbon copolymer used for film formation, texture and viscosity. Cosmetic safety reviewers concluded that butylene/ethylene/styrene copolymer is safe in current practices. Absorption of the intact polymer is expected to be limited.

Sources: CIR: Butylene/Ethylene/Styrene Copolymer final report, September 2014; CIR December 2025 Quick Reference Table https://cir-safety.org/sites/default/files/QRT-Update-Dec2025.pdf

Sources: CIR: Safety Assessment of Soy-Derived Ingredients as Used in Cosmetics; EU CosIng / cosmetics regulatory inventory

Eclipta Prostrata Extract

No Known Risks

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.

Bixa Orellana Seed Oil

No Known Risks

bixa orellana seed oil is a fixed plant oil used mainly as an emollient. CIR's plant-derived oil assessment supports cosmetic use, with refining, oxidation control and possible residual allergenic proteins remaining relevant. No pregnancy-specific concern was identified for normal topical exposure; this does not extend to concentrated essential oils or ingestion.

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.
