Science
Mechanism of Action
Operating as a non-ionic surfactant, Laureth-30 functions by significantly lowering the interfacial tension between disparate phases, such as oil and water. This action facilitates the formation and stability of emulsions, ensuring a consistent product texture. Additionally, it enhances the dissolution of lipid-soluble components within aqueous systems and exhibits mild cleansing properties.

Stability
This ingredient is robust within a pH range of 5.0 to 7.5, which aligns with the typical pH of its 5% aqueous solution. As a Laureth compound with a high ethoxylation number, Laureth-30 presents as a white, waxy solid; its solubility in water and hygroscopic nature diminish proportionally with increasing molar mass.
Safety
Safety Profile
The Cosmetic Ingredient Review (CIR) Expert Panel has affirmed the safety of Laureth ingredients, including Laureth-30, provided formulations are non-irritating. Studies on developmental, reproductive toxicity, and mutagenicity have yielded negative results. While 1,4-dioxane, an ethoxylation byproduct, may be present in trace amounts, these levels are controlled through stringent purification. For topical applications, Laureth-30 is restricted to a maximum concentration of 0.3% to ensure non-irritating properties.
