Science
Mechanism of Action
This compound acts as a non-ionic surfactant, effectively lowering surface tension to facilitate the creation of stable oil-in-water emulsions, crucial for creams and lotions. Its surfactant properties also enable mild cleansing by lifting impurities. Additionally, it serves as a skin conditioning agent and emollient, promoting a smoother skin feel, and aids in the solubilization of water-insoluble active ingredients. It can also modulate the rheological properties, specifically viscosity, of cosmetic formulations.

Stability
PPG-3-LAURETH-12 exhibits good solubility in water and low aliphatic alcohols, demonstrating its dual hydrophilic and lipophilic nature. It remains active across a wide range of conditions, including oxidizing, reducing, acidic, and neutral environments. However, it is susceptible to hydrolysis and potential decomposition at elevated pH levels.

Safety
Safety Profile
The Cosmetic Ingredient Review (CIR) Expert Panel has determined that Laureth ingredients, including Laureth-12, and polypropylene glycols (PPGs ≥3) are safe when formulated to be non-irritating. PPG-3-LAURETH-12, as an alkyl PEG/PPG ether, falls within this safety assessment. Formulators must ensure the final product is non-irritating, as Laureth-12 can be a potential moderate skin and eye irritant. Careful purification steps are necessary to minimize potential trace amounts of 1,4-dioxane, a by-product of its manufacturing process.
