    Product Description

    Docusate is a surfactant.1 It forms reverse micelles in oils and increases the solubility of water in oil by forming microemulsions. Docusate has been used in protein extraction, cryo-enzymology, the preparation of ceramic nanoparticles and gelatin-based nanopallets, and as a charge control agent in particle migration imaging.

    WARNING This product is not for human or veterinary use.
