Science
Mechanism of Action
This ingredient functions primarily by lowering the surface tension of liquids, which allows for thorough cleansing and removal of dirt, oil, and makeup. It supports product formulation by enhancing lather for a luxurious feel, stabilizing oil-and-water mixtures as an emulsifier, and contributing to desired product viscosity. As a polyethylene glycol (PEG) derivative, PEG-3 Lauramine Oxide further supports skin health by attracting and retaining moisture, helping to reduce transepidermal water loss. In acidic conditions, it can exhibit mild cationic properties.

Safety
Safety Profile
The Cosmetic Ingredient Review (CIR) Expert Panel deemed PEGs cocamine and related compounds, including close analogs like PEG-3 Lauramine Oxide, safe for cosmetic use when properly formulated to be non-irritating. For its non-PEGylated form, Lauramine Oxide, concentrations in leave-on products are generally limited to 3.7%. Individuals with sensitive skin should perform a patch test. The Environmental Working Group (EWG) flags higher concern for this ingredient in inhalable product forms due to potential respiratory concerns.
