The present invention is in the field of antimicrobial compositions, e.g. for personal care. In particular, the invention relates to antimicrobial compositions for oral care, such as toothpastes, comprising antimicrobial particles and a nonionic triblock copolymer. Accordingly, the present invention relates to antimicrobial compositions comprising a modified clay particle, the particle comprising an antimicrobial compound and a clay particle, and at least one a nonionic triblock copolymer. The invention further relates to the uses and methods of the antimicrobial compositions of the invention.

Antimicrobial compositions comprising modified clay and nonionic triblock copolymers

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. We have determined that antibacterial activity in relatively short contact times against gram positive and gram negative microorganisms in a soap based cleansing composition having silver compound enhances considerably in presence of a further salt of carboxylic acid. It has been additionally found that the antibacterial activity is enhanced even at very low concentrations of silver compound.

Antimicrobial cleansing composition

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.
