Science
Mechanism of Action
This ingredient functions by decreasing the surface tension of cosmetic formulations, which promotes even product distribution and aids in cleansing by effectively lifting dirt and oils. As an emulsifier, it is crucial for forming and stabilizing intimate mixtures of immiscible liquids like oil and water. Its skin conditioning properties are attributed to its ability to form hydrogen bonds with water molecules, thereby retaining moisture and reducing transepidermal water loss, particularly beneficial for dry skin.

Formulation
Stability
Polyethylene glycols and their derivatives are frequently utilized in cosmetic products due to their wide range of viscosity and solubility attributes, coupled with generally good skin tolerance and stability.
Safety
Safety Profile
The Cosmetic Ingredient Review (CIR) Expert Panel concluded that this ingredient, as part of the alkyl PEG/PPG ethers group, is safe under current practices of use and concentration when formulated to be non-irritating. While generally considered safe, manufacturers must diligently control potential impurities such as ethylene oxide and 1,4-dioxane, which are identified as potential human carcinogens. Additionally, this ingredient may function as a penetration enhancer. It is listed in the FDA's UNII database.
