Decyl β-D-maltopyranoside is widely used in biochemical research as a non-ionic detergent. It is particularly effective in solubilizing membrane proteins while maintaining their native structure and function, making it valuable for protein purification and crystallization studies. In the field of biotechnology, it aids in the study of protein-lipid interactions and the reconstitution of membrane proteins into lipid bilayers. Additionally, it is utilized in the formulation of cosmetics and personal care products, where it acts as a mild surfactant, enhancing the stability and texture of emulsions. Its ability to form micelles also makes it useful in drug delivery systems, where it helps improve the solubility and bioavailability of hydrophobic drugs.
