Mechanism of Action
As a non-ionic surfactant, Laureth-5 possesses a molecular structure with both hydrophilic and hydrophobic components. This dual nature allows it to accumulate at the interface between different phases, such as oil and water or dirt and skin. By reducing interfacial tension, it facilitates surface wetting, promoting the efficient removal and dispersion of impurities. Its emulsifying action helps combine and stabilize immiscible liquids like oil and water, and its solubilizing capacity allows for the incorporation of sparingly soluble ingredients into aqueous solutions.

Laureth-5 exhibits optimal stability and functionality within a pH range of 5.0 to 7.0, which corresponds to the pH observed in its 5% aqueous solution.
Safety
Safety Profile
The Cosmetic Ingredient Review (CIR) Expert Panel concluded that Laureth ingredients, including Laureth-5, are safe for use in cosmetic products when properly formulated to be non-irritating. Improper formulation, however, may lead to skin irritation. It is important to note that trace amounts of 1,4-dioxane, a by-product of the ethoxylation process, can be present; however, its levels are strictly controlled through purification steps during manufacturing to ensure safety.
