CITRUS AURANTIFOLIA FIBER.

The Cosmetic Ingredient Review (CIR) Expert Panel currently classifies Citrus Aurantifolia Fiber as having 'insufficient data' for a comprehensive safety assessment. While general citrus fruit-derived ingredients have been deemed safe by CIR when formulated to be non-sensitizing and non-irritating (specifically, leave-on products should contain no more than 0.0015% or 15 ppm of 5-methoxypsoralen), this guidance is not specific to the isolated fiber. The U.S. FDA generally recognizes citrus fruits as GRAS (Generally Recognized As Safe) for food use, and general citrus fiber also holds a GRAS notice for food applications as a texturizer and moisture retention agent. However, specific dermatological safety and benefit data for Citrus Aurantifolia Fiber in skincare are limited, with some sources noting it as 'not rated' and having 'no known benefits' in a cosmetic context.
