Sodium dodecyl sulphate (SDS), also known as sodium polyoxyethylene sulfate, ndi organic pawiri. It is a white crystalline solid with surfactant properties. Sodium dodecyl sulphate, with the formula C12H25SO4Na, is an anionic surfactant. Its molecular structure is composed of dodecyl chain and sulfate ion. In aqueous solution, mankhwala sodium dodecyl sulfate (cholimba) can form micellar structures with hydrophobic dodecyl chains facing inward and hydrophobic sulfate ions facing outward.
