Is it suitable during pregnancy?

MamaSkin rates the recorded formula for Tatcha The Water Cream 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), Diphenylsiloxy Phenyl Trimethicone (Low risk), Dimethicone/PEG-10/15 Crosspolymer (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.

34 of 35 ingredient entries on this page have a recorded score, evidence summary and source text. 1 entry does not have all of those fields. Unmatched or unrated entries are marked Not assessed in grey; missing evidence does not establish safety.

Ingredient ratings and evidence

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

Parfum

Low risk

Umbrella term for an undisclosed fragrance blend. It’s not usually a pregnancy-specific concern at normal cosmetic use levels, but the exact components and concentrations aren’t fully disclosed on the label, so we score it more conservatively. If you prefer maximum transparency (or you’re sensitive to fragrance compounds), choose fragrance-free/unscented products.

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

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.

Diphenylsiloxy Phenyl Trimethicone

Low risk

A phenyl-substituted silicone used for shine, conditioning and film formation. Cosmetic safety reviewers concluded it is safe in current cosmetic use but found insufficient evidence for products that may be incidentally inhaled. MamaSkin classifies it as low risk because of that route-specific evidence gap, not because of a known pregnancy-specific concern from ordinary topical use.

Sources: CIR: Safety Assessment of Phenyl-Substituted Methicones (Final Report 2023) https://www.cir-safety.org/sites/default/files/QRT-Update-Dec2025.pdf

Dimethicone/PEG-10/15 Crosspolymer

Low risk

A high-molecular-weight silicone polyether used for emulsification, texture and film formation. Cosmetic safety reviewers concluded that dimethicone crosspolymers are safe in current cosmetic use, and absorption of the intact polymer is expected to be limited. MamaSkin classifies this ingredient as low risk for consistency with its established dimethicone-family policy and because cosmetic-grade manufacturing should control residual starting materials, not because of a known pregnancy-specific contraindication.

CI 77891

No known risks

Colour Index name for titanium dioxide. Used as a pigment and (in some products) a mineral UV filter. For typical topical use in creams, lotions and makeup, systemic absorption is expected to be very low. Most concerns discussed in the literature relate to ingestion (E171) or inhalation from fine powders/sprays, and to nanoparticle characterisation. For routine topical cosmetic use, it is generally considered acceptable in pregnancy and breastfeeding; if you prefer a cautious approach, avoid inhaling loose powders or sprays.

The recorded formula includes 5 ingredient entries with risk flags: Dimethicone (Low risk), Diphenylsiloxy Phenyl Trimethicone (Low risk), Dimethicone/PEG-10/15 Crosspolymer (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. Incomplete ingredient documentation does not establish safety; see the coverage answer and grey entries below.

Has every ingredient in Tatcha The Water Cream been assessed?

34 of 35 ingredient entries on this page have a recorded score, evidence summary and source text. 1 entry does not have all of those fields. Unmatched or unrated entries are marked Not assessed in grey; missing evidence does not establish safety.

Does this assessment apply to my Tatcha The Water Cream?

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.
