Ethylene Distearamide
What is Ethylene Distearamide?
Ethylene Distearamide is a synthetic lipid derived from stearic acid, a saturated fatty acid often sourced from vegetable oils or animal fats, chemically bonded with ethylenediamine to form a diamide structure. This waxy solid functions mainly as a viscosity controller and opacifier in rinse-off and leave-on cosmetics like shampoos, conditioners, body washes, and moisturizers. In formulations, it increases thickness by creating a supportive matrix that suspends particles, prevents phase separation, and delivers a smooth, spreadable consistency. Its non-ionic nature allows compatibility across various pH levels and with other surfactants, while also imparting a subtle pearlescent sheen to products for aesthetic enhancement. Typically used at low levels, it supports overall formula integrity without contributing to greasiness or residue.
