Science
Mechanism of Action
This ingredient functions as an amphoteric surfactant, possessing both positively and negatively charged molecular components. This dual nature enables it to emulsify and lift dirt, oil, and other impurities from the skin's surface, allowing them to be easily rinsed away. It also acts as a foam booster, contributing to a rich, stable lather that optimizes the cleansing experience without inducing excessive dryness or irritation.

Safety Profile
The Cosmetic Ingredient Review (CIR) Expert Panel has not specifically evaluated Sodium Undecylenoamphopropionate, resulting in an 'insufficient data' status. However, related amphocarboxylates, such as Sodium Cocoamphoacetate and Disodium Cocoamphodipropionate, have generally been deemed safe for use in cosmetics. While Sodium Lauroamphoacetate was noted as non-irritating at a 0.5% aqueous solution, higher concentrations (40-50%) were associated with severe ocular irritation in studies. The absence of specific assessment for this exact ingredient suggests a need for dedicated safety research.

Verdict
While functioning as an effective cleansing and foam-boosting agent, specific safety and efficacy data for Sodium Undecylenoamphopropionate itself is currently insufficient to provide a definitive Moumoujus rating.
