Science
Mechanism of Action
This ingredient functions as an emulsifier, stabilizing oil and water components to achieve homogeneous product formulations. As a conditioning agent, it is believed to form a protective film or improve surface characteristics, contributing to enhanced smoothness and manageability of skin and hair. It also acts as a surfactant and a non-aqueous viscosity increasing agent.

Stability
Displays excellent stability across a wide range of pH values. Water solubility is extremely low at 9.0 x 10^-4 g/L at 23 °C, while solubility in n-octanol is high, ranging from 652–702 g/L at 20 °C.
Conflicts
- Must not be used in cosmetic products where the formation of N-nitroso compounds is possible.
- May be incompatible with strong oxidizing agents (e.g., hydrogen peroxide) in certain hair treatment formulations, potentially leading to decomposition.
