An algae-derived skin-conditioning ingredient. Cosmetic safety reviewers concluded that Fucus vesiculosus extract is safe in current practices, and available cosmetic use information does not identify a pregnancy-specific concern for Chlorella vulgaris extract. Algae allergy remains possible; this entry assesses topical cosmetics rather than concentrated oral seaweed supplements.

Bergamot essential oil used mainly for fragrance. No pregnancy-specific hazard is established for normal topical cosmetic exposure. Expressed bergamot oil can be phototoxic unless furocoumarins are controlled, so sun-exposed use should follow the finished product directions and applicable fragrance standards.

An exact label variant for lemon peel oil used mainly as a fragrance ingredient. At typical cosmetic concentrations there is no established pregnancy-specific concern. The main issues are oxidation, sensitisation and possible phototoxicity depending on composition, processing and use level.

Orange peel essential oil used mainly for fragrance. Normal topical cosmetic use has no established pregnancy-specific concern. The practical concerns are oxidation, irritation, sensitisation and, depending on composition and processing, light-related skin reactions.

A botanical extract, juice or water used primarily for skin conditioning, moisturising, soothing or antioxidant support. Direct pregnancy studies of the named cosmetic material were not identified. No reproductive or developmental hazard was identified for normal topical exposure to a compliant finished cosmetic; oral herbal or medicinal use is outside this classification.

An evening-primrose flower extract used for skin conditioning. No pregnancy- or breastfeeding-specific hazard was identified for normal topical cosmetic exposure. Direct ingredient-specific pregnancy studies were not identified, so this assessment does not extend to oral supplements or medicinal use.

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.

A Japanese elm root extract used as a skin-conditioning botanical. No pregnancy- or breastfeeding-specific hazard was identified for normal topical cosmetic exposure. Direct ingredient-specific pregnancy studies were not identified, so this assessment does not extend to oral supplements or medicinal use.

A botanical extract, juice or water used primarily for skin conditioning, moisturising, soothing or antioxidant support. Direct pregnancy studies of the named cosmetic material were not identified. No reproductive or developmental hazard was identified for normal topical exposure to a compliant finished cosmetic; oral herbal or medicinal use is outside this classification.

A grape fruit or seed extract used for skin conditioning and antioxidant support. Cosmetic safety reviewers concluded that the assessed Vitis vinifera-derived ingredients are safe in current practices when formulated to be non-irritating and non-sensitising. Botanical sensitivity remains possible.

A fruit, seed or food-plant extract used for skin conditioning and antioxidant support. No pregnancy-specific signal was identified for the low topical exposure expected from a finished cosmetic. Direct pregnancy studies are generally unavailable, and botanical allergy remains possible.

Camellia sinensis (green tea) leaf extract is used as an antioxidant botanical; topical cosmetic use is considered low concern with no known pregnancy or breastfeeding risks, though rare sensitivities are possible.

Chelating agent used to stabilise formulations; minimal dermal absorption and no known pregnancy or breastfeeding risks at typical cosmetic concentrations.

A mineral silicate used to thicken and suspend ingredients. Cosmetic safety reviewers concluded that silicates are safe in current practices when formulated to be non-irritating, but naturally sourced silicates lack enough evidence for products that may be incidentally inhaled. It is not expected to be meaningfully absorbed through skin.

Humectant and preservative booster used to support product stability. Low systemic exposure expected from topical cosmetic use.

This cellulose or modified-cellulose polymer is used as a thickener, film former or stabilizer. Cosmetic Ingredient Review data indicate that cellulose polymers do not appreciably penetrate skin and are safe in current cosmetic use, with at most minimal irritation reported.

Simple sugar used as a humectant and skin-conditioning support ingredient. Reviewed cosmetic ingredient references do not identify a pregnancy- or breastfeeding-specific concern for normal topical cosmetic use.

Solvent and humectant commonly used in leave-on products. Not associated with pregnancy-specific concerns at cosmetic exposure levels.

Allantoin is a soothing skin protectant commonly used to help reduce irritation and support comfort, with no known pregnancy or breastfeeding concerns in topical cosmetic use.

Short plant-derived carbohydrate chains used for skin conditioning and formula support. Cosmetic safety reviewers assessed fructooligosaccharides with plant polysaccharide gums and concluded that the group is safe in current practices. No pregnancy-specific concern was identified for normal topical cosmetic exposure.

This sugar or sugar alcohol is used as a humectant and skin-conditioning ingredient. Cosmetic Ingredient Review assessments support these saccharides in current cosmetic use, with no pregnancy- or breastfeeding-specific concern identified for normal topical exposure.

Preservative booster and skin-conditioning agent. Considered safe for cosmetic use with low systemic exposure when used as intended.

Chelating agent used to improve formula stability. Used at low levels and not associated with pregnancy-specific concerns.

Vitamin E antioxidant used to protect oils and support the skin barrier. Not associated with pregnancy-specific concerns at cosmetic exposure.

Humectant and preservative booster. Considered safe for cosmetic use with low systemic exposure.

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.
