  • Process for preparing an antimicrobial particulate composition
    Patent number: 10682298
    Abstract: The present invention relates to a process for preparing an antimicrobial particulate composition. The invention also relates to personal care or hygiene composition comprising an antimicrobial particulate composition obtainable by the process in accordance with this invention. The invention more particularly relates to a process for preparing an antimicrobial metal nanoparticles immobilized in an inorganic porous material and also incorporating these particles in personal care or hygiene compositions. The antimicrobial particulate composition comprises 0.05% to 3% by weight of antimicrobial metal particles and 97 to 99.95% by weight of immobilizer comprising an inorganic porous material selected from zinc oxide, magnesium hydroxide or calcium carbonate.
    Type: Grant
    Filed: July 16, 2015
    Date of Patent: June 16, 2020
    Assignee: CONOPCO, INC.
    Inventors: Somnath Das, Satyaranjan Gupta, Rupak Mitra, Girish Muralidharan, Amitava Pramanik

  • Antimicrobial cleansing composition
    Patent number: 9994691
    Abstract: The present invention relates to an antimicrobial cleansing composition and a method of cleaning or disinfecting a surface. The invention more particularly relates to an antimicrobial cleansing composition that provides antimicrobial efficacy in cleaning applications having relatively short contact times. An object of the present invention is to provide an antimicrobial cleansing composition that exhibits biocidal activity in relatively short contact times of 1 minute to 10 seconds. Another object of the present invention is to provide an antimicrobial cleansing composition which exhibits antimicrobial activity at very low concentration of silver compound. A further object of the present invention is to provide an antimicrobial cleansing composition which has consumer-acceptable aesthetic properties. A still further object of the present invention is to provide an antimicrobial composition that is highly efficacious against a broad spectrum of gram positive and gram negative bacteria.
