  • Mixed salts of hydroxyalkane sulfinic acid
    Patent number: 11053193
    Abstract: The preparation and use of mixed salts of hydroxyalkane sulfinic acids and optionally hydroxyalkane sulfonic acids as a reducing agent are disclosed. The reducing power of the salts is significantly higher than the reducing power of the corresponding zinc salt. The storage stability of the salts as solids and as aqueous solution is significantly higher than one of the corresponding sodium salts.
    Type: Grant
    Filed: December 12, 2017
    Date of Patent: July 6, 2021
    Assignee: L. BRÜGGEMANN GMBH & CO. KG
    Inventors: Josef Berghofer, Stefan Mark, Tamara Bittlingmayer, Jessica Schreiweis
  • Sulfonic acid salt composition and use thereof for color stabilization
    Patent number: 10662150
    Abstract: A sulfonic acid salt composition includes compounds of formula (I), wherein n is 1 or 2, R1 is H or C1-C6 alkyl, R2 is COOM, SO3M or CH(OH)SO2—OM, each M is an equivalent of a multivalent metal, preferably magnesium, calcium, aluminum, zinc and combinations thereof. The molar ratio of a compound wherein n is 1 to a compound wherein n is 2 is below 0.1. The sulfonic acid salt composition is useful for color stabilization of non-living organic matter such as from lacquers, paints, powder-coatings, and polymers in particular water-absorbent polymers.
