N-CYCLOPENTYL-M-AMINOPHENOL.

Avoid CAS 104903-49-3 / HAIR DYEING

N-CYCLOPENTYL-M-AMINOPHENOL is an aminophenol derivative primarily utilized as an oxidative precursor in permanent hair dyeing. Its function involves reacting to create colored molecules within the hair shaft, a process distinct from direct skincare benefits.

Summary

Science

Mechanism of Action

This compound's mechanism of action is specific to hair dyeing. It acts as a dye precursor, undergoing oxidation by hydrogen peroxide to generate reactive species. These species then combine with coupling agents inside the hair shaft, forming large, stable colored molecules that impart permanent hair color. This process does not translate to direct benefits for skin physiology or health.

Safety

Safety Profile

CIR Status
Not reviewed
Sensitization risk Unknown

This specific compound lacks a dedicated Cosmetic Ingredient Review (CIR) safety assessment or Scientific Committee on Consumer Safety (SCCS) opinion for skincare use. Safety data for structurally similar aminophenol hair dye ingredients, such as m-Aminophenol and p-Aminophenol, indicate potential concerns. m-Aminophenol was assessed as safe up to 2.0% (1.0% after mixing) in hair dyes, with a cautionary note regarding sensitization risk. p-Aminophenol, used up to 1.8% (0.9% after mixing), demonstrated irritancy in animal studies. While N-CYCLOPENTYL-M-AMINOPHENOL is registered with the FDA, hair dye components typically operate under different regulatory frameworks than direct skincare ingredients. Therefore, its safety profile for topical skincare applications remains uncharacterized.
