Science
Mechanism of Action
This ingredient reduces surface tension between oil and water, enabling the formation and stabilization of emulsions. As a surfactant, it aids in mixing water with oil and dirt for efficient rinsing during cleansing. Additionally, PEG-20 DILAURATE acts as a humectant to attract moisture, conditions the skin, and can enhance the penetration of other active ingredients.

The Formula
Formulation
Stability
Generally stable across a pH range of 4.5 to 7.5. For optimal formulation, ensuring the removal of impurities such as 1,4-dioxane and unreacted ethylene oxide residues is crucial.
Safety
Safety Profile
The CIR Expert Panel has concluded PEG-20 DILAURATE is safe for use in cosmetics up to 25%. While generally non-toxic to intact skin, concerns exist regarding moderate potential for allergies and immunotoxicity. Irritation and sensitization have been documented in individuals with compromised skin, such as burn patients. Trace amounts of 1,4-dioxane, a byproduct of the ethoxylation process, can be controlled through purification.
