An emulsifier built from polyglycerin, methyl glucose and stearic-acid components, used to stabilise creams and improve texture. Exact pregnancy-specific data are limited. Cosmetic safety reviewers concluded that related methyl glucose esters and polyglyceryl fatty-acid esters are safe in current cosmetic use when formulated to be non-irritating. No pregnancy-specific topical concern was identified by applying those related-group assessments to ordinary cosmetic exposure.

Stearic acid is a fatty acid used to stabilise emulsions and improve texture; it is considered low concern in topical cosmetics with no known pregnancy or breastfeeding risks at typical concentrations.
Sources: CIR; EU/UK Cosmetics Regulation
This naturally occurring fatty acid is used for emolliency, cleansing support or texture. The Cosmetic Ingredient Review concluded that assessed fatty acids are safe in current cosmetic use when formulated to be non-irritating and non-sensitizing; some can increase penetration of other formula ingredients.

Ingredient ratings refreshed 1 October 2026. Formulas vary by market and can change. Always compare with your packaging.
The recorded formula includes 1 ingredient entry with a risk flag: Lactic Acid (Low risk). These are ingredient-level flags; they do not replace the stored product assessment or account for every formulation detail. The product score is a stored assessment, not a clinical safety guarantee.
No. Niacinamide appears in the recorded formula, but its individual rating applies to that ingredient, not automatically to the whole product. Check the other ingredient ratings, any grey Not assessed entries and the stored product assessment. A niacinamide percentage or a product name is not a substitute for checking the full list.
19 of 19 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.
