Abstract: The present invention provides a perfuming composition that is free of ethanol and that is in the form of a transparent, clear microemulsion that contains a fragrance at a concentration of 0.5 to 50% by weight; a solvent at a concentration of 1 to 36% by weight; a non-ionic surfactant at a concentration of 1 to 35% by weight; an ionic surfactant at a concentration of 0 to 12% by weight, a cooling hydrotrope at a concentration of 0.01 to 12% by weight and water. Said microemulsions benefit from the presence of a cooling hydrotrope which allows lowering the amount of surfactant needed and provides a cooling effect.
