Egg Powder

Egg powder is produced by spray-drying or freeze-drying whole eggs, retaining the protein content and amino acids of fresh eggs in a stable, shelf-stable form. It contains both albumin (from egg white) and lipoproteins (from egg yolk), which contribute to its conditioning properties.In skincare formulations, egg powder functions primarily as a hair conditioning agent, though it may also be incorporated into face masks and topical products for its protein content. The ingredient is water-soluble when dispersed and can form a protective film on the skin or hair surface.

Egg powder works through two primary mechanisms. First, its high protein content (approximately 13% protein by weight in powdered form) can adhere to the hair shaft or skin surface, forming a protective film. This film reduces transepidermal water loss and can improve the feel and manageability of hair. Second, the amino acids and lipids present may interact with the outer layers of skin and hair, temporarily smoothing the cuticle layer and enhancing shine or softness.

Egg powder is most commonly found in rinse-off formulations such as hair masks and conditioning treatments, where it can be mixed into a paste and applied to damp hair or skin. In leave-on products, concentrations are typically low to avoid a heavy or sticky feel. For masks, apply to clean, damp hair or skin, leave for 10–15 minutes, and rinse thoroughly with lukewarm water.

Egg powder is generally well-tolerated and has a long history of use in cosmetics. However, individuals with egg allergies should avoid products containing egg powder, as processing does not guarantee complete removal of allergenic proteins.
