Expert Verdict

Critical: Free formaldehyde testing is mandatory. EU 2022/1181 sets 10 ppm labeling threshold for released formaldehyde. Products tested by Denmark's EPA found 75โ€“637 ppm free formaldehyde in nail products containing such resins. Melamine component raises additional concerns (triazine derivative). This ingredient is a prime candidate for reformulation away from formaldehyde-based resins. IARC Group 1 carcinogen (formaldehyde).
