Science
Mechanism of Action
This ingredient operates by significantly reducing the surface tension between immiscible liquids, allowing for the stable formation of emulsions. In cleansing applications, it effectively binds to oil-based impurities and dirt, enabling their dispersion in water for efficient rinsing from the skin and hair.

Stability
PEGs, including PEG-150 DILAURATE, are susceptible to oxidative degradation when exposed to air, particularly at elevated temperatures. Minimizing oxygen exposure or incorporating antioxidants can help preserve stability. For effective dissolution and incorporation into formulas, it is typically heated to 60°C (140°F), with its solubility often enhanced in the presence of other surfactants. It does not hydrolyze or promote mold growth during storage.

Safety Profile
The Cosmetic Ingredient Review (CIR) Expert Panel has concluded that PEG-150 DILAURATE, along with related PEG Dilaurate ingredients, is safe for use in cosmetics and personal care products at concentrations up to 25%. The FDA approves its use in cosmetics, but advises against application on broken skin. As a byproduct of ethoxylation, trace amounts of 1,4-dioxane may be present, necessitating stringent purification steps during manufacturing to ensure product safety.
