Di-HEMA TMHDC in Nail Products — Is It Safe?

Also known as: Di-HEMA Trimethylhexyl Dicarbamate

About Di-HEMA TMHDC

Di-HEMA TMHDC (Di-HEMA Trimethylhexyl Dicarbamate) was introduced as a 'safer' alternative to HEMA. However, studies show it is cross-reactive with HEMA and can trigger reactions in individuals already sensitized to HEMA. Many products labeled 'HEMA-free' contain Di-HEMA TMHDC — which is technically accurate but misleading. Our checker flags both ingredients.

Quick Answer

  • A product can be HEMA-free and still contain Di-HEMA TMHDC.
  • Di-HEMA TMHDC is not the same molecule as HEMA, but it remains relevant for acrylate allergy screening.
  • People with confirmed methacrylate allergy should not assume Di-HEMA formulas are tolerable.
