Science
Mechanism of Action
This dendrimer actively functions as an antioxidant, impeding oxygen-induced reactions that can lead to ingredient deterioration and cellular damage. On the skin, it acts as a conditioning agent, contributing to the maintenance of a healthy skin appearance. Its distinct molecular architecture, characterized by radial symmetry from an ethylenediamine core, also enables it to stabilize emulsions and serve as a binding agent for powdered components, ensuring product integrity.

Formulation
Stability
As a PAMAM dendrimer with an ethylenediamine core, this ingredient exhibits pH-dependent behavior. Its peripheral amino groups possess pKa values around 6.9, while internal tertiary amines have pKa values near 3.9, indicating that its charge and potential structural conformation are subject to changes based on the formulation's pH.
Safety
Safety Profile
The Cosmetic Ingredient Review (CIR) Expert Panel has concluded that acrylate copolymers, including this dendrimer, are safe for cosmetic use provided they are formulated to prevent irritation. A crucial consideration is the presence of ethylenediamine as a core component; as ethylenediamine is a potent sensitizer, meticulous formulation is essential to minimize potential skin irritation or sensitization.
