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).
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.

No higher-risk ingredient flags are shown in the assessed entries. Ingredients without a matched rating are marked Not assessed, not No known risks. The product score is a stored assessment, not a clinical safety guarantee.
30 of 30 ingredient entries on this page have a recorded score, evidence summary and source text. That describes documentation coverage, not proof that the finished formula has been clinically tested during pregnancy.
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.
No. This page presents a pregnancy-focused product assessment. Do not infer a breastfeeding conclusion from its score or label; breastfeeding requires a separate assessment of the formula and how it is used.
