A red or brown algae-derived ingredient used for skin conditioning, hydration or texture. Cosmetic safety reviewers concluded that Laminaria japonica extract and the assessed Chondrus crispus ingredients are safe in current practices of use and concentration. Seaweed allergy remains possible in a susceptible person.

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.

Phellodendron bark extract can contain biologically active alkaloids, with composition depending on extraction and source. Oral berberine cautions are not evidence of equivalent exposure from a topical cosmetic extract. No pregnancy-specific hazard was identified for normal topical cosmetic use.

A citrus fruit or peel extract used for skin conditioning and fragrance. Cosmetic safety reviewers concluded that these named citrus-derived ingredients are safe when formulated to be non-irritating and non-sensitising, and when leave-on products contain no more than 15 ppm 5-methoxypsoralen. Citrus sensitivity remains possible.

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.

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.

Hydrogenated emulsifier used to support skin barrier feel. Not associated with pregnancy-specific concerns.

Fatty alcohol used as an emollient and thickener. Not the same as drying alcohols and not associated with pregnancy-specific concerns.

Mineral absorbent and texture aid used to mattify and improve slip. Reviewed cosmetic safety sources support normal topical cosmetic use; this assessment does not cover deliberate inhalation of loose powder.

A terpene alcohol used for skin conditioning and soothing. Cosmetic safety reviewers reaffirmed bisabolol as safe at current cosmetic concentrations, and reproductive and developmental testing did not identify adverse effects. Bisabolol can increase skin penetration, so formulators should consider the safety of other ingredients in the same product.

An alkyl phosphate surfactant and emulsifier used to stabilise creams, sunscreens and makeup. Cosmetic safety reviewers concluded that the assessed alkyl phosphates, including potassium cetyl phosphate, are safe in current practices of use and concentration when formulated to be non-irritating. Dermal penetration is expected to be limited, and no pregnancy-specific concern is identified for normal topical cosmetic exposure.

A hydrolysed jojoba wax ester used for conditioning and texture. Cosmetic safety reviewers concluded that hydrolyzed jojoba esters are safe in current practices of use and concentration.

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.

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.

Large polymer thickener, stabilizer and texture ingredient used in gels, creams and sunscreens. Systemic exposure from topical cosmetic use is expected to be low, with no pregnancy- or breastfeeding-specific concern identified in reviewed cosmetic references.

A high-molecular-weight polymer used for film formation, texture or stabilisation. Meaningful dermal absorption is expected to be limited and no reproductive or developmental concern was identified for normal topical use.

Natural polysaccharide thickener used for stability and texture. Not associated with pregnancy-specific concerns.

A polyglycerin fatty-acid ester used as an emulsifier, dispersant or emollient. Cosmetic safety reviewers concluded that the assessed family of 274 polyglyceryl fatty acid esters is safe in current practices when formulated to be non-irritating.
