Science
Mechanism of Action
This ingredient operates by leveraging its amphiphilic molecular structure, possessing both lipophilic (oil-attracting) and hydrophilic (water-attracting) components. This dual nature allows it to significantly reduce the interfacial tension between immiscible liquids, thereby creating stable emulsions. As an emollient, it contributes to skin conditioning and moisture retention. Additionally, its surfactant properties facilitate the encapsulation and removal of dirt and oils from the skin surface. Polyethylene glycol (PEG) components are generally known to attract and bind water, forming hydrogen bonds that help maintain skin hydration and potentially enhance ingredient penetration by reducing transepidermal water loss.

Stability
As an effective emulsifier, it plays a crucial role in stabilizing formulations by creating a uniform dispersion of aqueous and oily phases, preventing separation.
Safety
Safety Profile
The Cosmetic Ingredient Review (CIR) Expert Panel has concluded that PEG-60 Glyceryl Triisostearate, within the broader category of 60 PEGylated alkyl glycerides, is safe for use in cosmetic practices and concentrations, provided formulations are non-irritating. The FDA has also recognized related PEGylated Glyceryl Isostearates as safe for certain food applications. While some similar PEGylated oils have been cleared for concentrations up to 100%, a precise maximum usage level for PEG-60 Glyceryl Triisostearate specifically was not identified in the provided CIR documentation.
