Ethylhexyl Methoxycinnamate

Medium risk

Ethylhexyl methoxycinnamate (EHMC) is a UV-B filter (also called octinoxate/octyl methoxycinnamate). SCCS characterised EHMC as endocrine-active (oestrogenic activity and weak anti-androgenic activity in vitro and in vivo) and reviewed genotoxicity/reproductive toxicity datasets in its re-evaluation. Pregnancy-specific human outcome data for topical exposure are limited; the medium-risk signal is endocrine activity plus systemic exposure uncertainty with frequent, large-area use.

Benzyl Salicylate

Medium risk

Benzyl salicylate is a fragrance ingredient that is also evaluated for potential endocrine activity and sensitisation. SCCS notes some indications for endocrine mode of action, and fragrance allergens are relevant for contact allergy risk; pregnancy-specific human outcome data for topical exposure are limited. The medium-risk signal is endocrine-related uncertainty and sensitisation potential rather than a defined pregnancy-specific toxicity dataset.

Sources: SCCS/1656/23: Benzyl salicylate https://health.ec.europa.eu/publications/benzyl-salicylate-cas-no-118-58-1-ec-no-204-262-9_en

Phenylbenzimidazole Sulfonic Acid

Low risk

Phenylbenzimidazole sulfonic acid (ensulizole/PBSA) is a water-soluble UV-B filter used in sunscreens and UV-protective skincare. Key consumer-relevant risks are local irritation and photoreactivity/photosensitisation potential in a small subset of users; systemic toxicity signals are generally low in the cosmetic context. It is not a typical pregnancy-specific concern at topical cosmetic use levels; overall risk is mainly local sensitivity.

Sources: TGA: Sunscreen review including phenylbenzimidazole sulfonic acid https://www.tga.gov.au/resources/publication/corporate-reports/safety-review-seven-active-sunscreen-ingredients

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

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.

Sources: CIR: Amended Safety Assessment of Dimethicone, Methicone, and Substituted-Methicone Polymers as Used in Cosmetics https://cir-safety.org/supplementaldoc/amended-safety-assessment-dimethicone-methicone-and-substituted-methicone-polymers-2

Dimethicone/Vinyl Dimethicone Crosspolymer

Low risk

A crosslinked silicone elastomer used for texture and oil absorption. Cosmetic safety reviewers concluded that dimethicone crosspolymers are safe in current cosmetic use. MamaSkin classifies the exact polymer as low risk for consistency with the existing dimethicone-family policy and because manufacturing controls are needed for residual monomers, rather than because of a known pregnancy-specific contraindication.

Sources: CIR: Safety Assessment of Dimethicone Crosspolymers as Used in Cosmetics https://www.cir-safety.org/sites/default/files/dimethcross_blue_092012.pdf

Dipotassium Glycyrrhizate

Low risk

A purified glycyrrhizic-acid salt used as a soothing and skin-conditioning ingredient. Cosmetic safety reviewers concluded that dipotassium glycyrrhizate is safe in current cosmetic use and noted poor dermal absorption. MamaSkin nevertheless applies a cautious low-risk classification for consistency with the existing licorice family because high oral glycyrrhizin exposure has pregnancy-related concerns; this is not a topical contraindication.

Incomplete ingredient documentation does not establish safety; see the coverage answer and grey entries below.

Is the MamaSkin score a measure of SPF or sun protection?

No. The score and risk band describe MamaSkin's pregnancy-focused ingredient screening of this recorded formula. They do not measure SPF, UVA protection, water resistance or whether you have applied enough sunscreen. Use the protection and application instructions on your exact packaging, and review the ingredient flags separately.

Has every ingredient in COSRX Aloe Soothing Sun Cream SPF 50 PA+++ been assessed?

44 of 45 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 COSRX Aloe Soothing Sun Cream SPF 50 PA+++?

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.
