LAURETH-2 BENZOATE.

Valuable / SKIN CONDITIONING - EMOLLIENT

Laureth-2 Benzoate is a multi-functional ester prized for its skin conditioning and emollient properties, which contribute to a softer, smoother skin texture. It also functions as a non-ionic surfactant and emulsifier, crucial for stabilizing cosmetic formulations and enhancing the solubility of various active compounds.

Skin conditioning Emollient Surfactant Emulsifier Solubilizer

Science

Mechanism of Action

This ingredient primarily operates as a skin conditioning agent, enhancing the feel and appearance of the skin, and as an emollient, which smooths and softens the epidermal surface. Its surfactant capabilities allow it to effectively lower surface tension, facilitating the miscibility of water with oils, sebum, and impurities, thus aiding in cleansing. As an emulsifier, it stabilizes formulations by enabling the uniform dispersion of immiscible liquids, preventing phase separation. Furthermore, it acts as a solubilizer, ensuring a wide range of hydrophobic perfumes and active ingredients are evenly distributed within a product.

Stability

Laureth-2 Benzoate is generally considered oil-soluble, with its emulsifying properties making it adept at blending oil and water phases within a formulation. Its Laureth-2 component exhibits chemical stability across a wide pH range, maintaining product quality optimally above pH 4.0. While Laureth-2 itself shows poor water solubility and better dissolves in low aliphatic alcohols like methanol or ethanol, its role as an emulsifier enables its integration into diverse product types.

Safety

Safety Profile

CIR Status
Safe with restrictions
Sensitization risk Low

The Cosmetic Ingredient Review (CIR) Expert Panel concluded that Laureth ingredients, including Laureth-2 (a constituent of Laureth-2 Benzoate), are safe for use in cosmetics when formulated to be non-irritating. Developmental, reproductive toxicity, and mutagenicity studies for these compounds yielded negative results. However, there is a recognized potential for skin irritation if not properly formulated, which necessitates the 'non-irritating' restriction. Additionally, trace amounts of 1,4-dioxane and ethylene oxide, by-products of ethoxylation, may be present, but their levels can be controlled through rigorous purification steps.
