Science
Mechanism of Action
This ingredient primarily functions as a humectant, attracting and binding water molecules to the skin's surface, which enhances hydration and minimizes transepidermal water loss. Furthermore, it serves as a solvent to homogenize various components and as an emulsifying surfactant, facilitating the stable dispersion of immiscible oil and water phases within a product.

Stability
Generally stable under normal storage conditions but should be protected from extreme temperatures. Formulators should note that PEG solutions can exhibit a low pH (e.g., 3) due to oxidation products, which may necessitate pH adjustment.
Safety
Safety Profile
The Cosmetic Ingredient Review Expert Panel (CIR) concluded that PEG-14 Laurate is safe for use in cosmetics at concentrations up to 25%, provided the products are formulated to be non-irritating. It is crucial for raw materials to be purified to remove potential impurities like 1,4-dioxane and unreacted ethylene oxide residues. Additionally, PEGylated ingredients can enhance the dermal penetration of other active ingredients, requiring caution when formulating with components whose safety profiles are predicated on limited skin absorption.
