Is it suitable during pregnancy?

MamaSkin rates the recorded formula for The Ordinary Azelaic Acid Suspension 10% as Low risk (71/100). Review the ingredient context and any manual-review explanation before deciding.

Why this rating?

The recorded formula includes 5 ingredient entries with risk flags: Dimethicone (Low risk), Azelaic Acid (Low risk), Polysilicone-11 (Low risk), plus others listed in the breakdown. These are ingredient-level flags; they do not replace the stored product assessment or account for every formulation detail.

17 of 17 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.

Ingredient ratings and evidence

Higher-risk flags first. Open an ingredient for evidence.

Triethanolamine

Low risk

Triethanolamine (TEA) is an alkanolamine used as a pH adjuster and surfactant in cosmetics. The main practical concerns are skin/eye irritation at higher concentrations and the potential formation of nitrosamines if formulated with nitrosating agents (a formulation/impurity-control issue). It is not a typical pregnancy-specific concern at cosmetic use levels; overall risk is primarily local irritation/sensitisation in susceptible users.

Phenoxyethanol

Low risk

Phenoxyethanol is a preservative permitted in EU cosmetics up to 1.0%. The SCCS concluded it is safe for cosmetic use at that level, including when considering higher cosmetic exposure scenarios in infants and young children. Main practical concern is irritation/stinging on very sensitive or compromised skin rather than a pregnancy- or breastfeeding-specific risk.

Dimethicone

Low risk

Dimethicone is a silicone polymer used as a skin protectant and slip/conditioning agent. It is considered inert with minimal dermal absorption; the main practical issues are cosmetic (feel) and occasional irritation in very sensitive users. It is not a pregnancy-specific concern in topical cosmetic use.

Azelaic Acid

Low risk

Azelaic acid is used topically for acne and pigmentation. MotherToBaby reports that ACOG lists OTC azelaic acid among ingredients that can be used during pregnancy if needed. Product information for 20% azelaic acid states that adequate controlled pregnancy studies are lacking, reports reassuring animal data and estimates about 3.6% absorption after a single topical dose. MamaSkin retains Low Risk while avoiding a categorical “pregnancy-safe” claim.

Polysilicone-11

Low risk

A crosslinked silicone elastomer used as a film former and texture ingredient. Cosmetic safety reviewers concluded that Polysilicone-11 is safe in current cosmetic use. MamaSkin classifies it as low risk for consistency with the existing silicone-polymer policy and because cosmetic-grade manufacturing should control residual starting materials, rather than because of a known pregnancy-specific contraindication.

Isodecyl Neopentanoate

No known risks

A fatty-acid ester used mainly for emollience, slip and formula texture. Cosmetic safety reviewers concluded that the assessed alkyl esters are safe in current practices when formulated to be non-irritating. No pregnancy-specific concern was identified for normal topical cosmetic exposure.

Dimethyl Isosorbide

No known risks

A solvent or preservative-support ingredient used to dissolve actives and stabilise a formula. No reproductive or pregnancy-specific signal was identified for the low concentrations used in finished topical cosmetics. Solvents can still increase local irritation or the delivery of other formula ingredients.

Hydroxyethyl Acrylate/Sodium Acryloyldimethyl Taurate Copolymer

No known risks

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.

Sources: CIR cosmetic ingredient safety references for acrylates copolymers; EU CosIng / cosmetics regulatory inventory

Isohexadecane

No known risks

Low-viscosity isoparaffin emollient used for slip and lightweight texture. Reviewed cosmetic safety sources support normal topical use, with no pregnancy- or breastfeeding-specific topical signal identified in the material reviewed.

Trisodium Ethylenediamine Disuccinate

No known risks

Chelating ingredient used to improve formula stability by binding trace metals. Reviewed cosmetic ingredient references do not identify a pregnancy- or breastfeeding-specific concern for normal topical use.

Isoceteth-20

No known risks

isoceteth-20 is used as a cosmetic surfactant, emulsifier or conditioning agent. Relevant cosmetic-safety assessments support use when formulated to be non-irritating and with appropriate impurity controls. Local skin or eye irritation is possible at higher concentrations, but no pregnancy-specific concern was identified for normal topical or rinse-off use.

Questions about this assessment

Why does The Ordinary Azelaic Acid Suspension 10% have a Low risk rating?

The recorded formula includes 5 ingredient entries with risk flags: Dimethicone (Low risk), Azelaic Acid (Low risk), Polysilicone-11 (Low risk), plus others listed in the breakdown. 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.

Is this assessment based only on the azelaic acid?

No. Azelaic Acid appears in the recorded ingredient list, but this page shows the finished product's stored assessment and the available ratings for its other ingredients too. An assessment of one headline ingredient does not establish the suitability of every formula containing it.

Has every ingredient in The Ordinary Azelaic Acid Suspension 10% been assessed?

17 of 17 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.

Does this assessment apply to my The Ordinary Azelaic Acid Suspension 10%?

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.

Does this pregnancy assessment also establish breastfeeding suitability?

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.
