Chlorphenesin

6.5

Ingredient Info

Chlorphenesin is a synthetic preservative used in skincare products to prevent bacterial and fungal growth, extending shelf life. It's a broad-spectrum antimicrobial agent that helps keep products safe from contamination during storage and use.



Benefits

  • Prevents microbial contamination in skincare formulations
  • Extends product shelf life
  • Allows formulas to remain stable without refrigeration

Potential concerns

  • May cause irritation to sensitive eyes and eye area when present in eye products
  • Degrades under UV exposure, potentially creating more harmful breakdown products
  • Limited long-term safety data in peer-reviewed literature

Science: Research shows chlorphenesin can be toxic to eye tissue cells at approved concentrations, particularly affecting meibomian glands. When exposed to sunlight, it breaks down into compounds like 4-chlorophenol that may be more ecotoxic than the original ingredient, though systemic absorption in skincare is typically minimal.
