Corn Syrup

What is Corn Syrup?

Corn syrup is a thick, sweet syrup produced by breaking down corn starch with enzymes or acids, yielding a mix of glucose, maltose, and higher saccharides. Originating from corn (Zea mays), it serves as a plant-based ingredient in cosmetics, appearing in moisturizers, cleansers, shampoos, and pressed powders. Functionally, it draws water from the environment into the skin's outer layer, promoting moisture retention without greasiness. In formulations, it binds particles for durable solids, adjusts flow for smooth application, and imparts a soft feel by conditioning the skin surface. Its natural hygroscopic nature and mild profile make it ideal for everyday products, enhancing usability across lotions, gels, and hair treatments while supporting overall product integrity.
