What Is Sodium PPG-16/PEG-2 Lauryl Ether Sulfate?
Sodium PPG-16/PEG-2 Lauryl Ether Sulfate is a synthetic surfactant—a type of cleaning agent derived from petrochemical sources. It belongs to the sulfate family of cleansing ingredients and is commonly used in skincare formulations to remove oils and impurities from the skin's surface.
In addition to cleansing, this ingredient functions as an emulsifier, helping oil and water-based components blend smoothly within a product. This dual role makes it a practical addition to cleansers, body washes, and some face wash formulations.
How It Works
As a surfactant, this ingredient works by reducing the surface tension of water, allowing it to penetrate oil-based substances on the skin. This enables the removal of lipophilic (oil-loving) contaminants—such as sebum and makeup—that would otherwise resist water-based rinsing.
Its emulsifying properties help keep the oil and water phases of a product stable and evenly distributed, which is essential for consistent product performance and texture.
Clinical Evidence & References
Sodium PPG-16/PEG-2 Lauryl Ether Sulfate is widely used in commercial skincare and personal care products, with a long history of use in the industry. However, dedicated clinical studies specifically evaluating this ingredient's efficacy or safety profile in skincare are limited.
Sulfate-based surfactants in general are recognised as effective cleansers, though individual tolerance varies. As with other sulfates, it may be drying or irritating for some users, particularly those with sensitive or compromised skin barriers, but this is typically dependent on concentration and formulation context.
How to Use
This ingredient is most commonly encountered in rinse-off formulations such as cleansers and body washes. Apply to damp skin, massage gently, and rinse thoroughly with water. If used in a leave-on product, follow the product instructions. Those new to sulfate-based cleansers may wish to introduce it gradually and observe how their skin responds.
