Lauramide DEA
Low risk
A diethanolamide surfactant and foam booster closely related to Cocamide DEA. Historical concerns centre on residual free diethanolamine and formation of N-nitrosodiethanolamine when DEA amides are combined with nitrosating agents; concentrated material can also irritate skin or eyes. CIR has reviewed Lauramide DEA within the DEA-amide group, with manufacturing and formulation restrictions intended to control these concerns. No human pregnancy contraindication from normal topical cosmetic use was identified, but MamaSkin assigns a precautionary low-risk band for consistency with its existing Cocamide DEA policy.

Salicylic Acid
Low risk
Salicylic acid is a beta-hydroxy acid (BHA) used for acne, exfoliation and preservation. Common over-the-counter acne strengths are 0.5-2%, including 0.5%, 1% and 2%; the FDA lists this acne-treatment range. Pregnancy guidance distinguishes these topical products from oral salicylates and strong peels. MotherToBaby reports that ACOG allows over-the-counter topical salicylic acid during pregnancy when needed. Only a small amount of topical acne treatment usually reaches the bloodstream through intact skin; exposure can increase with damaged skin, frequent use or treatment of large areas. Direct salicylic-acid-specific pregnancy data remain limited. MamaSkin's Low Risk rating is a dose-and-use precaution, not evidence that ordinary low-strength skincare causes fetal harm or a recommendation to avoid every BHA product. Use as directed on limited areas of intact skin. Discuss strengths above 2%, chemical peels, wart/corn removers, large-area treatment or use under occlusion with your clinician before use during pregnancy. The American Academy of Dermatology specifically advises discussing and limiting higher-strength salicylic acid above 2%. Percentage alone does not establish safety: formulation, area, frequency and skin condition also matter. General cosmetic-use limits are not pregnancy-specific safety thresholds.

Myristic Acid
No known risks
This naturally occurring fatty acid is used for emolliency, cleansing support or texture. The Cosmetic Ingredient Review concluded that assessed fatty acids are safe in current cosmetic use when formulated to be non-irritating and non-sensitizing; some can increase penetration of other formula ingredients.

PEG-32
No known risks
A polyethylene glycol used as a humectant, solvent or texture aid. Cosmetic safety reviewers concluded that PEG-32 is safe in current practices of use and concentration. Manufacturing controls should limit residual ethylene oxide and 1,4-dioxane.

Potassium Hydroxide
No known risks
A strongly alkaline raw material used mainly in small amounts to adjust pH or during soap manufacture. Concentrated potassium hydroxide is corrosive, but that raw-material hazard is not representative of a correctly formulated finished cosmetic. Cosmetic safety reviewers concluded that inorganic hydroxides are safe in current cosmetic uses when products are formulated to be non-irritating, with special handling conditions for depilatories and hair straighteners. No pregnancy-specific concern is identified for normal use of a compliant finished product.

Lavandula Hybrida Oil
No known risks
Lavandin oil, a volatile fragrance oil that may irritate or sensitise susceptible skin. Available cosmetic and fragrance information focuses on irritation, sensitisation and constituent quality. No pregnancy-specific hazard was identified for normal topical exposure to a compliant finished cosmetic.
Sources: European Commission CosIng ingredient inventory; Cosmetic Ingredient Review botanical safety-assessment framework and relevant ingredient-family assessments. No ingredient-specific human pregnancy study of normal topical cosmetic use was identified.
Linalool

Asiaticoside
No known risks
A triterpene glycoside associated with Centella asiatica and used in soothing and skin-conditioning formulas. Pregnancy-specific evidence for isolated topical asiaticoside is limited. Cosmetic safety reviewers considered Centella-derived ingredients acceptable at current cosmetic exposure but noted that asiaticoside and related triterpenes may contribute to sensitisation. No pregnancy-specific topical contraindication was identified in the reviewed material.

Questions about this assessment
Why does COSRX AC Collection Calming Foam Cleanser have a Low risk rating?
The recorded formula includes 2 ingredient entries with risk flags: Lauramide DEA (Low risk), Salicylic Acid (Low risk). 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.
Has every ingredient in COSRX AC Collection Calming Foam Cleanser been assessed?
24 of 24 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 COSRX AC Collection Calming Foam Cleanser?
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.
