Maltose

What is Maltose?

Maltose is a disaccharide carbohydrate formed by two glucose molecules linked via an alpha-1,4 glycosidic bond, typically obtained through enzymatic hydrolysis of starches from grains like barley or corn. In cosmetics, it appears in moisturizers, cleansers, shampoos, and oral care items. Functioning as a humectant, it binds water molecules to the skin's outer layer, supporting moisture retention without greasiness. As a skin conditioning agent, it helps preserve the skin's natural barrier, fostering a supple texture. Its inherent mild sweetness allows it to impart a pleasant taste in lip products and toothpastes, while also neutralizing off-notes for better sensory appeal. Maltose integrates seamlessly into water-based formulas, aiding viscosity and stability due to its hygroscopic properties.
