Detajet e produktit

Sulfat dodecil natriumi (SDS), also known as sodium polyoxyethylene sulfate, është një përbërje organike. It is a white crystalline solid with surfactant properties. Sulfat dodecil natriumi, with the formula C12H25SO4Na, is an anionic surfactant. Its molecular structure is composed of dodecyl chain and sulfate ion. In aqueous solution, sulfat kimik natriumi dodecil sulfat (solid) can form micellar structures with hydrophobic dodecyl chains facing inward and hydrophobic sulfate ions facing outward.
