Is The Ordinary Natural Moisturizing Factors + HA suitable during pregnancy?

MamaSkin currently classifies The Ordinary Natural Moisturizing Factors + HA as Low risk, with a stored score of 75/100. This is a precautionary classification, not an unqualified pregnancy-safe recommendation. Read the ingredient context and any manual-review explanation below.

What does the ingredient evidence show?

The recorded formula includes 2 ingredient entries with risk flags: Triethanolamine (Low risk), Phenoxyethanol (Low risk). These are ingredient-level flags; they do not replace the stored product assessment or account for every formulation detail.

45 of 46 ingredient entries on this page have a recorded score, evidence summary and source text. 1 entry does not have all of those fields. Unmatched entries retain the default No known risks label but are not independently assessed here; missing evidence does not establish safety.

Ingredients

Ingredients with a higher risk flag appear first, followed by the rest of the formula.

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.

Sources: CIR: Triethanolamine ingredient safety information https://www.cir-safety.org/ingredient/triethanolamine

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.

Sources: SCCS/1575/16: Phenoxyethanol opinion https://health.ec.europa.eu/publications/phenoxyethanol_en

Water

No Known Risks

Water (aqua) is the purified solvent used as the base of many cosmetics. MamaSkin classifies plain water as No known risks for normal topical use. Cosmetic water quality must be controlled to prevent contamination; this entry does not cover botanical waters or establish the safety of the finished formula.

Questions about this assessment

Has every ingredient in The Ordinary Natural Moisturizing Factors + HA been assessed?

45 of 46 ingredient entries on this page have a recorded score, evidence summary and source text. 1 entry does not have all of those fields. Unmatched entries retain the default No known risks label but are not independently assessed here; missing evidence does not establish safety.

Does this assessment apply to the The Ordinary Natural Moisturizing Factors + HA I have?

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.

How to use this assessment

The risk band is the primary conclusion. The score adds detail within that band and should not be used to compare products as if a one-point difference were clinically meaningful.

MamaSkin provides pregnancy-focused information, not medical advice. Your midwife, GP, pharmacist or dermatologist should take priority when your circumstances differ from typical cosmetic use.
