Abstract
The invention concerns a transparent perfume composition substantially free of volatile organic solvents and in the form of an oil-in-water emulsion. The oil phase contains perfume ingredients, and the difference between the refractive indices of the oil phase and the aqueous phase is less than 0.003. This is achieved by adding agents with certain refractive indices to each of said phases.

Perfuming composition in the form of a oil-in-water or water-in-oil emulsion having an oil phase containing 15% to 60% by weight of one or more perfuming ingredients, said composition containing from 5 to 50% by weight of a dispersed phase and from 50 to 95% by weight of a continuous phase, with the difference between the refractive index n of the dispersed phase and the continuous phase being less than or equal to 0.003.
Perfuming composition in the form of a transparent oil-in-water emulsion having a viscosity which is below than 10 Pa.s and comprising:
- 5 to 50% by weight of a dispersed oily phase containing 15% to 60% by weight of one or more perfuming ingredients, and from 50 to 95% by weight of a continuous aqueous phase, with the difference between the refractive index n of the dispersed phase and the continuous phase being less than or equal to 0.003.
Perfuming composition in the form of a transparent water-in-oil emulsion having a viscosity which is below than 10 Pa.s and comprising:
- 5 to 50% by weight of a dispersed aqueous phase containing 15% to 60% by weight of one or more perfuming ingredients, and from 50 to 95% by weight of a continuous oily phase, with the difference between the refractive index n of the dispersed phase and the continuous phase being less than or equal to 0.003.
