Laureth-2 Benzoate
What is Laureth-2 Benzoate?
Laureth-2 Benzoate is a clear, synthetic ester created by reacting Laureth-2—a polyethylene glycol ether of lauryl alcohol with two ethylene oxide units—with benzoic acid. Derived from petrochemical sources, it belongs to the class of ethoxylated benzoates commonly used in rinse-off and leave-on cosmetics like shampoos, conditioners, lotions, and cleansers. In formulations, it acts as an emollient, providing a smooth, slippery feel by temporarily filling skin irregularities and enhancing spreadability. It also functions as a solubilizer, enabling the incorporation of hydrophobic fragrances and oils into water-based products, which improves stability and sensory experience without altering the formula's clarity or viscosity significantly.
