Lauramide DEA (Diethanolamine Lauramide) and Propylene Glycol blend is a common formulation aid used in personal care products. Lauramide DEA functions as a foam booster, thickener, and viscosity modifier in surfactant-based systems, while Propylene Glycol acts as a humectant and solvent. Together, they improve the texture, stability, and performance of shampoos, body washes, facial cleansers, and other cleansing formulations. This blend enhances foaming while maintaining mildness and skin compatibility.
