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.
