Science
Mechanism of Action
As an azo chromophore, PIGMENT RED 112 functions by absorbing specific wavelengths of light within the visible spectrum through its -N=N- molecular structure. This absorption selectively reflects light, resulting in the perception of a vibrant red color.

Dusting Analysis
PIGMENT RED 112 is a well-defined colorant, and its role in cosmetic formulations is purely aesthetic. There are no known claims of skincare efficacy that would raise 'dusting' concerns.
The Formula
Formulation
Stability
This pigment demonstrates excellent stability against heat, acids, and alkalis, making it robust in diverse formulations. It maintains integrity in weak acidic solutions (pH 4-6) and withstands temperatures up to 140-180°C. It also exhibits good lightfastness. Although poorly soluble in water, it disperses effectively in both water-based and solvent-based systems.
Safety
Safety Profile
PIGMENT RED 112 (CI 12370) is recognized as a cosmetic colorant, though its use is subject to regional restrictions. In some areas, it is permitted only in products with brief skin contact and is explicitly forbidden in hair dyes. Notably, the EU imposes a strict concentration limit of 0.1% by weight for its use in tattoo inks and permanent make-up. There is a documented potential to cause an allergic skin reaction (H317).
