  • Patent number: 6346648
    Abstract: The present invention deals with novel compounds their applications and a process their preparation. The compounds are novel amphoteric surfactants that contain a hydroxyl group and two carboxylic groups per hydroxyl group. The compounds have a unique structure, having multiple carboxyl groups on each amino group. The utility for these novel polymers is as softening, anti-tangle, and conditioning agents for use in personal care, textile and related applications.

  • Patent number: 6315835
    Abstract: Cleaning formulations and methods are provided by which solid deposition is inhibited on hydrophobic hard surfaces typically encountered in bathroom and outdoor environments without detrimentally affecting the appearance of such surfaces. The formulations most preferably include an aqueous mixture of an organically solvated nonionic copolymer, a polyacrylic acid homopolymer and a nonionic surfactant. Optionally, a hydrotrope may also be present in the formulation. Most preferably, the formulations of this invention have a pH between about 4.0 to about 7.0, most preferably around neutral (i.e., about 7.0).
