  • Complex salt for anti-spotting detergents
    Publication number: 20040048764
    Abstract: Provided is a complex salt for anti-spotting detergents, the complex salt being formed by the reaction of a photo-bleaching component having a water-soluble anionic substituent and a cationic surfactant. The complex salt is water insoluble in a stationary state, such as hand washing or pre-soaking for machine washing, so it effectively suppress the spotting of the photo-bleaching component into the interwoven webs of fabric. In addition, the complex salt can uniformly and rapidly dissolve in an agitating state, such as when machine washing, to allow the photo-bleaching component to absorb into fabric for effective bleaching and enhanced detergency.
