Albumin

What is Albumin?

Albumin is a simple, water-soluble protein typically sourced from animal origins like egg whites, where it exists as ovalbumin, or from serum in milk and blood. In the cosmetic industry, it falls under protein-based ingredients and appears in products such as mascaras, shampoos, conditioners, and moisturizers. Its primary mechanism involves denaturing upon application to create a sheer, continuous sheath over skin or hair strands. This film boosts product staying power, shields against environmental factors, and imparts a smooth feel. Additionally, its humectant-like qualities help retain surface moisture, while its large molecular structure limits penetration, focusing effects on the outer layers for conditioning without deep absorption.
