The invention relates to a transparent/translucent liquid antimicrobial composition which comprises disinfectants of natural origin. It is a challenge to incorporate these disinfectants in aqueous composition while maintaining high transparency/ translucency. Further, these compositions are sold in concentrate forms and it is required for the consumer to dilute the compositions with water before use. It is advantageous to provide a visual cue of turbidity on dilution to indicate to the consumer that the desired dilution has been carried out. The present invention provides a solution to the above problem by way of incorporating the antimicrobial agents in a specific microemulsion composition that ensures a transparent appearance when stored and transported and gives a turbid/ cloudy appearance when diluted with water. The turbidity is enabled in short time span after the composition is diluted with water.
