Science
Mechanism of Action
Acting as a non-ionic surfactant, Laureth-2 reduces the surface tension between different phases, allowing it to effectively emulsify lipids and impurities on the skin's surface, making them soluble in water for removal. As an emulsifier, it creates stable dispersions of immiscible liquids, ensuring consistent product texture and ingredient distribution. Furthermore, it can modify a formulation's rheology, acting as a thickening agent, and enhances the solubility of various active compounds and fragrances within a matrix.

Stability
Laureth-2 demonstrates robust chemical stability across a wide pH spectrum, with product quality maintained above a pH value of 4.0. It is effective in oxidizing, reducing, and hard water environments. While poorly soluble in water, forming cloudy solutions, it dissolves readily in low aliphatic alcohols such as methanol or ethanol.
Conflicts
- Requires stringent purification to remove trace amounts of 1,4-dioxane, a potential byproduct of the ethoxylation process.
Safety
Safety Profile
The Cosmetic Ingredient Review (CIR) Expert Panel concluded that Laureth ingredients, including Laureth-2, are safe for use in cosmetic products when formulated to be non-irritating. Developmental and reproductive toxicity studies, as well as mutagenicity data, were all negative. Small amounts of 1,4-dioxane may be present as a manufacturing byproduct; its presence is manageable and can be controlled through purification steps prior to blending into cosmetic formulations, a standard for precision skincare.
