ETHANOL-FREE MICROEMULSION PERFUMING COMPOSITIONS |
| 摘要 |
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. |

1. A perfuming composition in the form of a transparent and EtOH-free microemulsion comprising:
0.5% to 50% of a fragrance oil; 1.0% to 36% of a solvent; a surfactant system comprising:
a) at least a non-ionic surfactant present in an amount of 1.0% to 35%; andb) at least a ionic surfactant present in an amount of 0% to 12%; 0.01% to 12% of at least a cooling hydrotrope; and water;wherein the perfuming composition remains stable during freeze-thaw cycles from −25° C. to 50° C., and wherein all concentrations are based on the weight of the composition. |
