Laureth-12

Laureth-12 is a non-ionic surfactant derived from lauryl alcohol and ethylene oxide. It belongs to the polyethylene glycol ether family of emulsifiers, commonly used in cosmetic formulations to blend water and oil-based ingredients that would otherwise separate.In skincare products, Laureth-12 serves primarily as an emulsifying agent and mild cleansing surfactant. It helps create stable, uniform textures in creams, lotions, and cleansing formulations whilst remaining relatively gentle on the skin barrier.

Surfactants like Laureth-12 have a dual chemical structure: one end is water-loving (hydrophilic) and the other is oil-loving (lipophilic). This allows the molecule to sit at the boundary between water and oil, holding them in stable suspension within a formulation.When used in cleansers, Laureth-12 works by surrounding oil and dirt particles on the skin surface, allowing them to be rinsed away with water. As a non-ionic surfactant, it is milder than many alternatives and less likely to disrupt the skin's natural barrier.

Laureth-12 is typically a background ingredient rather than an active component, so no special usage instructions are needed beyond following the product's general guidance. Its presence helps ensure your product maintains its intended texture and stability over time, so using it as directed will allow the formulation to work as designed.

Laureth-12 is generally well-tolerated and considered safe in cosmetic formulations. Those with very sensitive skin or known sensitivity to surfactants may want to patch-test products containing this ingredient first.
