Summary

Humectant Skin Conditioning Antioxidant

Science

Mechanism of Action

This extract primarily operates as a humectant, significantly reducing transepidermal water loss and preventing dehydration by attracting and retaining moisture within the stratum corneum. Furthermore, it acts as a skin conditioning agent, helping to ameliorate the appearance of damaged or dry skin by diminishing flakiness and enhancing elasticity. Its composition, rich in compounds such as flavonoids, terpenes, linalool, and vitamin C, also endows it with notable antioxidant capabilities.

Conflicts

  • Formulation must ensure the final product is non-irritating and non-sensitizing to the skin.
  • For leave-on formulations, the concentration of 5-methoxypsoralen (5-MOP) must be strictly controlled not to exceed 0.0015% (15 ppm) to mitigate potential phototoxicity.

Sensitization risk Unknown

The Cosmetic Ingredient Review (CIR) Expert Panel affirms the safety of Citrus fruit-derived ingredients, including Citrus Tankan Fruit Extract, for use in both rinse-off and leave-on cosmetic products, provided they are formulated to be non-irritating and non-sensitizing. For leave-on applications, strict adherence to a maximum 5-methoxypsoralen (5-MOP) concentration of 0.0015% (15 ppm) is critical to prevent phototoxic reactions. The U.S. FDA also generally regards Citrus fruits as safe (GRAS) for direct food consumption.
