Driven by Ammonium Lauryl Sulfate (Caredermis editorial assessment)
Ingredients with a documented concern, from official datasets and our reviewed database.
surfactant
A strong anionic cleanser similar to SLS, appropriate only in well-formulated rinse-off products.
fragrance
An umbrella term that can hide dozens of undisclosed scent chemicals. Fragrance is the leading cause of allergic contact dermatitis from cosmetics, and dermatologists routinely advise fragrance-free products for eczema, babies and sensitive skin.
solvent
Plain ethanol — position on the label matters: near the top it is drying; near the bottom it is a harmless solvent trace.
humectant · solvent
A workhorse humectant and penetration enhancer that is fine for most, but a recurring culprit in eczema patients' patch tests.
surfactant
A mild coconut-derived surfactant in countless 'gentle' cleansers. Most allergy is caused by manufacturing impurities, so quality varies by brand.
preservative
A mild food-grade preservative usually paired with sodium benzoate; well tolerated by most skin types.
preservative
A food-grade preservative generally regarded as one of the gentler options; occasional non-immune stinging is its main drawback.
Ingredients rated likely to clog pores — relevant if your skin is acne-prone. This is a separate indicator and is not part of the safety score.
Indicative Fulton-scale ratings from published dermatology references — not a regulator classification; individual reactions vary.
Ingredients that are unflagged in our reviewed database, reviewed safe by the CIR panel, or on an EU permitted list.
Catalogued in official cosmetic-ingredient inventories (EU CosIng and others) with no safety flag on record. Being recognized isn't a safety guarantee — it means the ingredient is on record but no authority has published a concern.
This report is informational, not medical advice. Assessments summarize published findings (EU CosIng, IARC, ECHA, CIR, SCCS and others) about ingredients — not clinical testing of this specific product. Exposure, concentration and individual sensitivity all matter. Consult a dermatologist for medical concerns.
