  • Cleaning composition containing an organic acid and a spore forming microbial composition
    Patent number: 6387874
    Abstract: Described is an aqueous cleaning composition comprising: an effective mineral dissolving amount of an organic acid of at least 5% by weight of the cleaning compositions; an effective amount of a spore forming microbial composition; an effective cleaning amount of a blend of wetting agents, the first wetting agent having a hydrophobic/lipophobic number (HLB) of about 10 and higher and a second wetting agent having an HLB number of about 5 or less; an effective amount of a thickening agent and water. The composition is also available in powder form without the thickening agent.
    Type: Grant

  • Aqueous disinfectant and hard surface cleaning composition and method of use
    Patent number: 6180585
    Abstract: Described is An aqueous disinfectant and hard surface cleaning composition comprising: an effective disinfecting amount of a quaternary ammonium compound; an effective amount of a spore forming microbial composition; and an effective water dispersing amount of a surfactant. The composition is used to clean a hard surface containing a diverse microbial flora. The composition cleans and disinfects by killing off undesirable microorganisms which may be causing offensive odors and leaves behind Bacillus spores which will then germinate and degrade any remaining ongoing residues without creating offensive odors.
