PEG-4 POLYGLYCERYL-2 DISTEARATE.

Valuable CAS 86360-24-9 / SURFACTANT - EMULSIFYING

PEG-4 POLYGLYCERYL-2 DISTEARATE is a versatile ingredient functioning as an emulsifier, surfactant, and skin conditioning agent. It is crucial for stabilizing oil-in-water emulsions, enhancing product texture, and improving spreadability on the skin.

Science

Mechanism of Action

This ingredient primarily acts as a surfactant, effectively reducing the surface tension to facilitate the formation of stable, finely dispersed oil-in-water (O/W) emulsions. As a co-emulsifier, it contributes to the creation of complex three-phase emulsions involving water, a dispersed fluid, and a liquid crystalline gel network, which significantly boosts emulsion stability and increases viscosity. Furthermore, it functions as an emollient, providing skin conditioning benefits and imparting a less greasy feel to formulations.

Stability

Polyglyceryl emulsifiers, including this compound, demonstrate robust stability across a broad pH range and good tolerance to electrolytes. Its capacity to form liquid crystalline gel networks is pivotal for enhancing emulsion stability and controlling viscosity. For optimal emulsion integrity, it should be paired with a co-emulsifier having a melting point significantly higher than room temperature. This ingredient is suitable for cold-process manufacturing, promoting energy efficiency.

Synergies

  • Functions optimally as a co-emulsifier when combined with other emulsifiers possessing higher melting points, which aids in forming stable liquid crystalline gel networks for oil-in-water emulsions.

Safety

Safety Profile

CIR Status
Safe as used
Sensitization risk Low

The Cosmetic Ingredient Review (CIR) Expert Panel has determined that PEG-4 POLYGLYCERYL-2 DISTEARATE, as part of the PEG distearates group, is safe for cosmetic application. It presents a low risk of irritation or sensitization and is listed in the US FDA Voluntary Cosmetic Registration Program (VCRP) database. The Environmental Working Group (EWG) also assigns low concern ratings for cancer, allergies & immunotoxicity, and developmental & reproductive toxicity. However, EWG notes that its risk score may increase if used in inhalable product forms (e.g., sprays, powders) due to potential respiratory concerns, or in cases of contamination from toxic impurities.
