Science
Mechanism of Action
This ingredient operates as an effective surfactant, meticulously reducing interfacial tension to create stable oil-in-water emulsions. Its molecular architecture, comprising both lipophilic and hydrophilic segments, is crucial for its emulsifying capabilities. Furthermore, as a polyethylene glycol derivative, it can contribute to skin hydration by forming hydrogen bonds with water molecules, thus aiding in moisture retention and mitigating transepidermal water loss. Glycerin-based fatty acid esters are also known to improve skin's moisture equilibrium.

Stability
Polyethylene glycols and their derivatives exhibit robust stability and are generally not prone to microbiological degradation, which can lessen the necessity for additional preservatives. This ingredient maintains stability across a pH range of 4.0 to 9.0.
Safety
Safety Profile
The CIR Expert Panel has determined that PEG diesters are safe for cosmetic use when formulated to be non-irritating. Clinical studies on related PEG Stearates, at concentrations up to 25%, showed them to be non-irritating and non-sensitizing. The FDA also recognizes 'Peg 15 Glyceryl Isostearate' as safe for specific, limited food applications.
