Science
Mechanism of Action
This ingredient functions by forming a substantive film on the surface of skin and hair, acting as both an emollient and a conditioning agent. Its polymeric structure, derived from soya, ensures superior adhesion, contributing to improved skin hydration, softening, and smoothing. For hair, it reduces friction, making strands easier to comb, while imparting a supple, soft, and shiny finish.

The Formula
Formulation
Stability
DI-PEG-2 SOYAMINE IPDI, as a component of the Polyderm polyurethane series, exhibits excellent thermolytic stability and resistance to hydrolysis across a broad pH spectrum, encompassing both high and low pH conditions. Polyethylene glycols and their derivatives typically offer diverse viscosity and solubility characteristics with good dermal tolerance.
Safety
Safety Profile
While DI-PEG-2 SOYAMINE IPDI has not undergone a formal safety review by the Cosmetic Ingredient Review (CIR) Expert Panel, a chemically related compound, PEG-2 Soyamine, was deemed safe for cosmetic application when formulated to prevent irritation. Data from the European Chemicals Agency (ECHA), referenced by EWG Skin Deep, indicates limited evidence of dermal toxicity or allergic reactions. However, caution is advised for products containing this ingredient if intended for inhalable forms (e.g., sprays), due to potential respiratory concerns, or in cases where there is a risk of contamination from toxic impurities.
