Safety
Safety Profile
The Cosmetic Ingredient Review (CIR) has not yet assessed Dilaureth-4 Dimonium Chloride. Paula's Choice highlights a significant 'likelihood of irritation,' potentially leading to inflammation or dryness, especially when co-formulated with other concerning ingredients. The EWG lists broad concerns, including 'May cause cancer' and 'Known to cause reproductive toxicity (to females),' based on general hazard classifications (GHS, California Proposition 65); these are not specific assessments for cosmetic use concentrations. Furthermore, this ingredient is generally not permitted in EWG VERIFIED products without substantial additional data.

Verdict
