Contact sensitization to p-tertiary butylphenol (PTBP) Resin in plastic nail adhesive

Abstract

Nail dystrophy and dermatitis of the nail folds and finger tips are reported in three women using the same brand of adhesive (Eylure® Nailfix®) to affix plastic nails (Eylure®). Contact sensitization to p‐tertiary butylphenol (PTBP) resin was demonstrated in ail patients. The subcontractor responsible for supplying the adhesive had changed just prior to the outbreak of symptoms. The new subcontractor subsequently confirmed that there was PTBP resin in their formulation. The subcontract has since reverted to the original company.
