Подробности за продукта

Натриев додецил сулфат (SDS), also known as sodium polyoxyethylene sulfate, е органично съединение. It is a white crystalline solid with surfactant properties. Натриев додецил сулфат, with the formula C12H25SO4Na, is an anionic surfactant. Its molecular structure is composed of dodecyl chain and sulfate ion. In aqueous solution, химически натриев додецил сулфат (твърд) can form micellar structures with hydrophobic dodecyl chains facing inward and hydrophobic sulfate ions facing outward.
