Dibutyl Adipate

No known risks

A diester used as an emollient, solvent and plasticizer. After reviewing additional dermal, reproductive, developmental and genotoxicity data, cosmetic safety reviewers concluded that dibutyl adipate is safe in current cosmetic use and concentration. No pregnancy-specific concern is identified for normal topical cosmetic exposure.

Propanediol

No known risks

Solvent and humectant used to improve texture and ingredient solubility. Low systemic exposure expected from topical cosmetic use.

Sources: Cosmetic Ingredient Review (US); Scientific Committee on Consumer Safety (EU)

Diethylamino Hydroxybenzoyl Hexyl Benzoate

No known risks

Modern UVA filter (often called Uvinul A+ or DHHB). Regulatory assessments have repeatedly evaluated this filter as safe in cosmetic products at concentrations up to 10%. The most recent SCCS advice focuses on controlling a manufacturing impurity (DnHexP) rather than on new toxicity of DHHB itself. Human biomonitoring data indicate low systemic exposure from normal sunscreen use, and current reviews do not identify specific reproductive or developmental toxicity signals at approved concentrations.

Sources: SCCP opinion referenced in Directive 2008/123/EC: concludes that Diethylamino Hydroxybenzoyl Hexyl Benzoate used at a maximum of 10% in cosmetic (including sunscreen) products does not pose a risk to the consumer. Regulatory summaries (e.g. CosLaw and CIRS Group updates, 2025) reviewing the SCCS DHHB opinion and reiterating that DHHB remains permitted up to 10% in EU cosmetics when impurity limits are respected.

Polymethylsilsesquioxane

No known risks

A silicone resin used as a film former, texture enhancer and opacifying ingredient in makeup, sunscreen and skin care. The Cosmetic Ingredient Review concluded that polysilsesquioxanes including Polymethylsilsesquioxane are safe in current cosmetic use. Available evidence does not identify a pregnancy- or breastfeeding-specific concern for normal topical cosmetic exposure.

Ethylhexyl Triazone

No known risks

UV filter used in sunscreens and day products to help absorb UVB radiation. Reviewed cosmetic safety and regulatory sources support current cosmetic use within applicable concentration limits, with no pregnancy- or breastfeeding-specific topical concern identified in the material reviewed.

Sources: EU CosIng Annex VI / UV filters; EU scientific opinion on Ethylhexyl Triazone (Uvinul T 150)

Niacinamide

No known risks

Sources: CIR; EU/UK Cosmetics Regulation

Methylene Bis-Benzotriazolyl Tetramethylbutylphenol

No known risks

Hybrid particulate UV filter (often referred to as Tinosorb M or Bisoctrizole). It behaves more like an inorganic, microfine filter, forming a film on the skin surface with minimal percutaneous absorption. EU Scientific Committee on Consumer Safety (SCCS) opinions on both conventional and nano forms support its safe use in dermally applied cosmetic products up to 10% under current conditions of use, with main caution relating to inhalation of spray products rather than systemic toxicity from normal topical application.

Sources: SCCS opinions on Methylene Bis-Benzotriazolyl Tetramethylbutylphenol (MBBT), including SCCS/1460/11 and SCCS/1546/15: conclude that MBBT used as a UV filter up to 10% in dermal cosmetic products is safe under the evaluated conditions of use. European Commission, revision opinion on Methylene Bis-Benzotriazolyl Tetramethylbutylphenol (nano form), 2015: confirms safety of nano MBBT up to 10% in dermally applied cosmetics when used according to specified conditions

Coco-Caprylate/Caprate

Macrocystis Pyrifera Extract

No known risks

A brown-algae-derived extract used for skin conditioning and hydration. Cosmetic safety reviewers specifically included this ingredient in the small subset of brown algae extracts found safe in current practices of use and concentration. Manufacturers should control naturally occurring iodine, arsenic and heavy-metal impurities.

Panax Ginseng Root Extract

No known risks

A botanical root extract used as a skin-conditioning and antioxidant ingredient. Cosmetic safety reviewers concluded that Panax root-derived ingredients are safe in current practices of use and concentration.

Monascus/Rice Ferment

No known risks

No pregnancy-specific harm has been identified from ordinary finished topical cosmetics containing Monascus/Rice Ferment; direct pregnancy and breastfeeding studies are limited. This rating applies to ordinary cosmetic use, not oral red-yeast-rice supplements, medicinal use or concentrated raw material. Fermentation constituents can vary, and some raw materials sold under this ingredient name are standardised to monacolins, including the statin-like compound monacolin K. The ingredient name alone does not show that a cosmetic contains such a preparation or receives an equivalent drug dose. A product documented to contain a monacolin-standardised preparation needs a separate composition-and-exposure assessment and may warrant Low Risk or a higher product-specific precaution. There is no validated topical pregnancy-safe percentage for this ferment. No Known Risks means no identified risk for the stated cosmetic use, not proof of safety for every preparation.

Questions about this assessment

Why does Beauty of Joseon Relief Sun : Rice + Probiotics SPF 50+ PA++++ have a No known risks rating?

No higher-risk ingredient flags are shown in the assessed entries. Ingredients without a matched rating are marked Not assessed, not No known risks. The product score is a stored assessment, not a clinical safety guarantee.

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 Beauty of Joseon Relief Sun : Rice + Probiotics SPF 50+ PA++++ been assessed?

42 of 42 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 Beauty of Joseon Relief Sun : Rice + Probiotics 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.
