Science
Mechanism of Action
This copolymer is understood to function by creating a stable, continuous film upon application, which contributes to skin conditioning and can provide a barrier against moisture loss and external aggressors. Its polymeric nature also allows it to increase the thickness of liquid formulations, acting as a viscosity enhancer. Furthermore, it aids in dispersing and lubricating other ingredients and is utilized to stabilize complex emulsion systems, such as water-in-gelled oil or silicone-in-gelled oil, imparting water and sweat resistance.

Safety
Safety Profile
Specific safety data for Ethylenediamine/Stearyl Dimer Tallate Copolymer is currently limited. The Cosmetic Ingredient Review (CIR) Expert Panel has indicated 'insufficient data' for this ingredient and noted that 'significant data needs remain' for the broader 'Dimer Dilinoleates' category. While closely related Dialkyl Dimer Dilinoleates have been deemed safe by the CIR Panel when formulated to be non-irritating, and a related Ethylenediamine/stearyl dimer dilinoleate copolymer is rated with 'LOW' concern for cancer and immunotoxicity by EWG Skin Deep, direct safety data for the tallate form remains under review.
