Egg
What is Egg?
Egg refers to powdered or extracted material from chicken eggs, rich in proteins such as ovalbumin and ovomucoid, along with yolk-derived lipids, lecithin, and vitamins. In cosmetics, it appears mainly in hair care formulations like shampoos, conditioners, and masks, as well as some skin creams and lotions. It works by forming a protective film on hair shafts and skin surfaces, which reduces friction, retains moisture, and imparts a smooth texture. The proteins mimic natural hair keratin for better manageability, while fats and emulsifiers nourish and hydrate, making it suitable for rinse-off products where it delivers conditioning without residue buildup.
