Common emollient derived from fatty acids and glycerin. Used to soften skin and improve texture without pregnancy-specific concerns.
Sources: Cosmetic Ingredient Review (US); Scientific Committee on Consumer Safety (EU)
1,2-Hexanediol is commonly used as a solvent and preservative booster; topical exposure is low and it has no known pregnancy or breastfeeding concerns at cosmetic concentrations, though very sensitive skin may occasionally react.
Sources: CIR; EU/UK Cosmetics Regulation
A naturally sourced clay used as an absorbent, bulking agent or texture aid. CIR concluded that Hectorite, Illite and Montmorillonite are safe in current cosmetic practices, except that available data are insufficient for products that may be incidentally inhaled. No pregnancy-specific systemic concern was identified for topical use; cosmetic-grade sourcing should control crystalline silica, heavy metals and microbial contamination.

Fatty alcohol used to improve texture and skin feel. Considered safe for cosmetic use without pregnancy-specific concerns.
Sources: Cosmetic Ingredient Review (US); Scientific Committee on Consumer Safety (EU)
Self-emulsifying form of glyceryl stearate used to stabilize creams and lotions. Reviewed cosmetic safety sources support normal topical use, with no pregnancy- or breastfeeding-specific concern identified.

Emollient ester/emulsifier used to improve skin feel and stabilise emulsions. Reviewed cosmetic safety sources support topical cosmetic use; the relevant practical caveat is formulation irritation potential rather than a pregnancy-specific concern.
Sources: CIR: Amended Safety Assessment of Alkyl Esters as Used in Cosmetics; CIR Quick Reference Table (Cetearyl Olivate); EU CosIng / cosmetics regulatory inventory
Olive-derived sorbitan ester used as an emulsifier and skin-conditioning ingredient. Reviewed cosmetic safety references do not identify a pregnancy- or breastfeeding-specific concern for normal topical use.

No pregnancy-specific harm has been identified for ordinary, correctly formulated topical cosmetic use of phaseolus angularis seed extract. This is a bounded botanical/extract assessment; direct pregnancy studies of the exact material are limited and oral, medicinal, damaged-skin or aerosol exposure is not included.
Pigment used to add blue/violet tones in makeup. In typical topical use it has very low dermal absorption and is generally considered acceptable in pregnancy and breastfeeding. If you prefer a cautious approach, avoid inhaling loose powders or sprays.
Sources: General cosmetic ingredient safety references for pigments; exposure route considerations for powders/sprays.
A botanical extract, plant water or plant juice used for conditioning, soothing or antioxidant support. Direct pregnancy studies of this exact cosmetic material were not identified, but no reproductive or developmental hazard was identified for normal topical exposure. Oral herbal or medicinal use is outside this classification.
Sources: European Commission CosIng ingredient inventory; CIR botanical safety framework and relevant plant-derived ingredient assessments; no ingredient-specific human pregnancy study of normal topical cosmetic use was identified.
Preservative booster and skin-conditioning agent. Considered safe for cosmetic use with low systemic exposure when used as intended.
Sources: Scientific Committee on Consumer Safety (EU); Cosmetic Ingredient Review (US)
A large synthetic polymer used to thicken and stabilise cosmetic emulsions. Related acrylate copolymers have low dermal absorption because of their molecular size, and cosmetic safety reviewers concluded that this polymer family is safe when formulas avoid irritation and residual monomers are appropriately controlled. Exact pregnancy-specific topical studies are limited, but no pregnancy-specific concern was identified for normal exposure to the finished polymer in a compliant cosmetic.

A botanical extract or plant water used for conditioning, soothing or antioxidant support. Direct pregnancy studies of this exact cosmetic material were not identified, but no reproductive or developmental hazard was identified for normal topical exposure. Oral herbal or medicinal use is outside this classification.
Sources: European Commission CosIng; CIR botanical safety framework and relevant plant-family assessments; no ingredient-specific human pregnancy study of normal topical cosmetic use was identified.
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.
