  • Zinc salt of a hydrolyzed tricarboxylic acid from ene-adducts of maleic anhydride to undecylenic acid
    Patent number: 4454153
    Abstract: The zinc salt of the hydrolyzed tricarboxylic acid from Diels-Alder adducts or ene-adducts of maleic anhydride to undecylenic acid, preferably in a molar ratio of from 0.8 to 1.2, are described as skin-compatible bactericides and fungicides. They are preferably used in cosmetic preparations. They are more active and less toxic than the substances previously known and used for said purposes.
    Type: Grant
    Filed: July 21, 1982
    Date of Patent: June 12, 1984
    Assignee: Grillo-Werke Aktiengesellschaft
    Inventors: Norbert Lowicki, Natvarlal B. Desai
  • Surfactants which are polyhydric alcohol partial esters of adducts of maleic anhydride with an unsaturated carboxylic acid
    Patent number: 4376789
    Abstract: Disclosed are novel polyhydric alcohol partial esters of polycarboxylic acids from Diels-Alder adducts of maleic anhydride and a straight chain unsaturated carboxylic acid having ten to twenty-five carbon atoms. The partial esters can be subsequently sulfated.The polyhydric alcohol can be a mono- or disaccharide such as sucrose or mannose.The partial esters are surfactants which are dermatologially acceptable and useful in personal products and skin-care products.

  • Method of preventing incrustation on heated surfaces, and composition for the practice of the method
    Patent number: 4087371
    Abstract: Method of preventing deposits of dissolved inorganic salts on heated surfaces, such as tubular heat exchangers, is carried out by adding a deposit-preventing agent to the water before contact with the heated surfaces. Compounds complexing with cations are combined with anionic substances which are capable of salt formation with complex bound cations to form additive compositions which are added to the water in the zone near the walls of vessels or tubular heat exchangers subject to deposit incrustation.
