Egg Yolk Extract

What is Egg Yolk Extract?

Egg Yolk Extract is derived from the yolks of chicken eggs, a natural source abundant in lecithin—a phospholipid complex—along with proteins, lipids, cholesterol, and fat-soluble vitamins like A, D, and E. Primarily featured in skincare emulsions, lotions, creams, shampoos, and conditioners, it functions as a surfactant and emulsifier. Lecithin lowers surface tension between oil and water phases, stabilizing mixtures for uniform product textures and aiding dispersion in cleansing formulations. Its lipid and protein components deposit on skin and hair cuticles, forming emollient films that enhance smoothness and flexibility. This biocompatible ingredient supports product efficacy in rinse-off and leave-on cosmetics by promoting even application and mild interaction with biological surfaces.
