  • Publication number: 20190327975
    Abstract: The present invention relates to an antimicrobial composition and more particularly an antimicrobial composition for cleansing applications that provides antimicrobial efficacy in relatively short contact times. Accordingly, the present invention provides an antimicrobial composition comprising: a) 0.1 to 100 ppm by weight of a silver compound; b) a salt of a sulphonic acid; and, c) 1 to 85% by weight of a salt of fatty acid wherein, the sulphonic acid is an aromatic sulphonic acid.

  • 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.

  • Patent number: 9756855
    Abstract: The invention relates to an antimicrobial particle and to a composition for use in personal or home care products comprising the same. The invention also relates to a process for preparing the antimicrobial particle. The antimicrobial particle comprises thymol and terpineol incorporated in a cage-forming inorganic silicate or aluminosilicate particle which is coated with a coating material selected from a water soluble alkali or alkaline earth metal salt.

  • Publication number: 20150086421
    Abstract: The present invention relates to a method of disinfecting a surface and to an antibacterial composition. Essential oils, which are used as antibacterial actives, are also known for their strong odour; using high amounts of these gives a strong smell to the product that is not always appreciated by the consumer. It is therefore an object of the invention to provide an antibacterial composition, having good anti-bacterial properties, at very low levels of essential oil actives. The present inventors have achieved this using a synergistic combination of select anti-bacterial actives, specific polymers and select hydrotropes.
