Science
Mechanism of Action
This polyesteramine functions as a film-forming and skin conditioning agent. Its inherent cationic activity, coupled with high hydrophobicity, delivers a lubricious feel. In cleansing systems, POLYESTER-11 interacts electrostatically and hydrophobically with surfactant molecules, thereby mitigating their engagement with the skin's lipid bilayers and significantly enhancing formula mildness.

The Formula
Formulation
Stability
Optimal water solubility is observed below pH 6.0 and is substantially improved in the presence of surfactants. This ingredient is pH-responsive, acquiring transient cationic charges in acidic environments. As a pourable liquid, it is highly formulator-friendly, suitable for cold processing, and ideal for creating clear formulas.
