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.

The antiseptic and fragrance-free soap includes about 5% to 30% percent by weight of deionized water, about 3% to 10% by weight of caustic soda, about 25% to 90% by weight of vegetable fat, and about 0.1% to 1% by weight of antibacterial nanoparticles. The vegetable fat can be selected from the group consisting of olive oil, coconut oil, palm oil, almond oil, jojoba oil, shea butter, or a combination thereof. The antibacterial nanoparticles are preferably silver nanoparticles made by any conventional method.

A multi-purpose cleaner system for providing a composition for cleaning at least one surface. The multi-purpose cleaner composition is all natural and cleans a variety of surfaces like flooring, glass, counter tops, porcelain, grout, and many more. At least one essential oil is included in the multi-purpose cleaner composition to provide aromatherapy benefits. The multi-purpose cleaner system is intended for continuous use in order to deliver healthier and aesthetically pleasing surfaces.
